I’ve coached many runners and want to key on one individual who has agreed to share his training data. I’ve actually coached this runner personally for the last 20 years and he had some pretty terrific coaches previously with some strong results. That’s the background and here are my observations about the athlete who is dealing with a glute injury that shortens his stride. The runner intends to keep volume relatively high (~35 mpw), while he flosses, rolls and stretches his glutes. On a Wednesday session, I suggested cutting the 9M @ 7:19/M pace to ~ 6M at 7:30/M pace and running progressively to RPE (rate of perceived effort/exertion) = 5-6. Here’s a graph of how that run transpired: Notice the athlete did have a nice progressive run shaping up until 5M. Now let me overlay HR against pace so I can show you where the problem arose: Notice the gentle cardiac drift initially, which is exactly what we want. Then around 2.5M there’s a steeper inflection with a final mile that looks like a cool down (it was not). Instead the runner over heated and drove RPE + HR too high. In reality it was a hot day in the SF Bay Area. When I say “hot day in the SF Bay Area”, we are talking relative to the typical area conditions. For those of you in the midwest, southeast and Atlantic coast, you are dealing with much worse conditions. Here’s the synopsis given by the athlete post-run: After 5M I felt hot, heavy and my glutes were tight. I had intended to run a gradual progression, but got ahead of myself in M3 and was tired by the slow last mile. It easy to see this from the splits: Ok I’m being pretty critical of this athlete so full disclosure, the athlete referenced = ME. After my failed attempt at <5:00/M on July 2, I recommitted to making my goal. The problem is that I’m partially injured and instead of listening to the Angel (coach in me) and slowing down with emphasis on rehab, I let the Ego (athlete in me) take control. The point is that after coaching thousands of runners and spending myriad time on a track, I still fall victim to the same self-sabotage thoughts that derail us. I ignore the weather and my aches & pains. However, I continue to strive to be better. So now I need to go into a Do as I say, Not as I do recommendations list:-)
The summer heat has been a challenge for most of the world (Europe included), so let’s consider heat index:
As I (the athlete) reflected on that Wednesday run I realized the Heat Index was ~ 90. That’s high for the Bay Area and definitely affected my performance. I could’ve stayed at ~ 8:00/M pace and kept HR comfortably in Zone 3, but gee that Ego is powerful and I wanted to run the assigned pace.

The Run You Keep AvoidingJuly 14, 2026Most runners have one! The workout that makes you hesitate when you see it on the schedule. Maybe it's speed work. Maybe it's hills. Maybe it's the long run that feels intimidating before you even start. Whatever it is, most runners have a session they would rather skip, shorten, or push to another day. However, the run you keep avoiding might be the one that helps you grow the most. Why We Avoid Certain Workouts Usually, it’s not because we’re lazy or unmotivated. We avoid the runs that challenge us. Speed workouts can feel intimidating because they force us to run at uncomfortable paces. Intervals require us to push beyond our comfort zone. Long runs demand patience and commitment. Hills test our strength and remind us that running doesn't always get easier. These workouts expose our weaknesses. And that’s exactly why they are valuable. The areas where we feel the most uncomfortable often reveal the biggest opportunities for improvement. Find The Run You Avoid Ask yourself:
Your answer can tell you a lot about where you have room to grow. Avoidance is a clue. It points directly toward the strength or confidence you need to develop. Turn Weakness Into Strength The goal isn’t to force yourself through every difficult workout and make training miserable. The goal is to approach those challenging sessions with a different mindset.
Don’t Let Fear Make Your Training Decisions It's normal to feel nervous before a hard workout. Even experienced runners have days where they look at the schedule and think, "Do I really have to do this today?" The difference is that they don't let that feeling decide for them. Confidence doesn't come from avoiding hard things. It comes from doing hard things and realizing you can handle them. Every challenging workout you complete gives you evidence that you are becoming a stronger runner. Start Small If you've been avoiding a certain type of workout, you don't need to suddenly make it the hardest session of your training cycle. Start by changing your approach.
The goal isn't to eliminate discomfort. The goal is to become more comfortable being uncomfortable. The Workout You Avoid Might Be Your Advantage Your hardest workout is your greatest opportunity. The thing you keep avoiding may be the exact thing that helps you become a more complete runner. So the next time you see that workout on your schedule, the one you hope gets changed, shortened, or canceled, pay attention. It might not be the workout standing in your way. It might be the workout that helps you move forward!

What's Slowing You Down?July 14, 2026If you've been running for any length of time, you've probably asked yourself some version of this question: "Why am I not getting faster?" Most runners immediately look for physical reasons. Maybe they need more speed work. Maybe they're not running enough miles. Maybe it's nutrition, sleep, strength training, or the summer heat. Those factors of course matter. But after coaching runners of all abilities, I've learned that the biggest thing slowing people down often isn't physical at all. It's what they're comparing themselves to. Every runner compares themselves to something: a training partner, a runner they follow online, a recent race result, or perhaps most commonly, the version of themselves from years ago. The problem isn't comparison itself, it's allowing those comparisons to shape your confidence, your decisions, and even your enjoyment of the sport. The Comparison Trap Running is unique because it's so easy to compare. Every run produces data. Pace, distance, heart rate, cadence, elevation, splits. Add social media into the mix, and suddenly you're surrounded by runners posting race medals, workout screenshots, and personal records. Before long, it's easy to wonder why your progress doesn't look like theirs. Maybe your training partner seems to improve every month. Maybe someone in your local running club just qualified for Boston. Maybe a friend who started running after you is now faster. It's natural to notice those things. The problem comes when they begin to shape how you feel about your own training. Comparison has a way of making strong, consistent work feel like it isn't enough. Chasing a Different Version of Yourself Not all comparisons involve other runners. Some of the toughest ones happen in your own head. Many runners spend years trying to match a pace they ran years ago. Every workout becomes a comparison to a race result, a season of training, or a version of themselves that felt unstoppable. But here's the thing: you're not the same runner you were then, and that's not a bad thing. Maybe you're balancing a demanding career. Maybe you're raising kids, caring for family members, or juggling more responsibilities than you were a decade ago. Maybe you're sleeping less, traveling more, or fitting runs into the margins of a busy schedule. Those circumstances matter. Comparing today's training to a time in your life when you had different routines, different stress levels, or more time to recover isn't an apples-to-apples comparison. That doesn't mean you can't run just as fast, or even faster. Plenty of runners set personal bests later in life because they're training smarter, fueling better, or simply bringing years of experience and consistency to the sport. When you shift your focus from recreating the past to maximizing the present, your training becomes far more productive, and way more enjoyable. When Your Training Partners Become Your Competition Training with others is one of the great perks of running. Long runs feel shorter, difficult workouts become more manageable, and accountability is built into every meeting. However, group runs only help if you're still running your plan. One of the most common mistakes I see is runners turning every easy run into an unofficial race. Your schedule calls for an easy effort, but your friends naturally run a minute per mile faster. Rather than backing off, you match them because you don't want to fall behind. The run feels manageable that day. The problem shows up later. Your legs stay tired longer. Recovery slows. Workout days become harder than they should be. Eventually, fitness stalls, not because you're training too little, but because you're training too hard on the days that were supposed to help you recover. Sometimes the smartest runner in the group is the one willing to let everyone else disappear down the road. Don't Let One Bad Run Tell the Whole Story Every runner has those days. Your legs feel flat. Your watch shows paces that seem slower than normal. Nothing clicks. It's tempting to assume you've lost fitness overnight. In reality, running doesn't work that way. Heat and humidity slow pace. Poor sleep affects recovery. Travel, work stress, and accumulated fatigue all influence how your body responds on any given day. One difficult run rarely tells you much about your overall fitness. Improvement happens over weeks and months, not from one workout to the next. The runners who continue improving aren't the ones who never have bad days. They're the ones who don't let a bad day define the entire training cycle. Focus on What You Can Control There are countless things you can't control, but what you can control is really simple! Did you complete today's run? Did you keep your easy run easy? Did you fuel well before your long run? Did you prioritize recovery? Will you come back tomorrow? Those small decisions rarely feel exciting in the moment, but they add up over months of training. Fitness isn't built through big breakthroughs. It's built through consistency. Success Looks Different in Every Season Not every training block ends with a personal best. Sometimes success means making it through an entire cycle without getting injured. Sometimes it means rebuilding after illness. Sometimes it's finding a routine that fits around work, family, and everything else life demands. Those seasons matter just as much. Progress isn't always measured by the clock. Sometimes it's measured by showing up when motivation is low, finishing healthy, or enjoying the process a little more than you did last season. Run Your Own Race If comparison is slowing you down, don’t forget, no one else has your story. No one else has your schedule, your responsibilities, your strengths, or your challenges. Your training doesn't need to look like anyone else's to be successful.

Why Your Summer Pace Is Slower And Why That's OkayJune 07, 2026Every summer, it happens. A runner heads out the door feeling fit, motivated, and ready to crush a workout. The pace that felt comfortable in April suddenly feels impossible. Heart rate climbs. Breathing becomes labored. Frustration follows. The immediate reaction is often, "I've lost fitness." But in most cases, that's not true at all. The reality is that heat and humidity place additional stress on the body, making the same pace require more effort. Understanding how to adjust your training during the summer months can help you train more effectively, recover better, and avoid the mental trap of chasing paces that no longer match the conditions. The Weather Impacts Your Pace A pace that feels comfortable on a 55-degree morning may feel significantly harder on an 80-degree afternoon. Add humidity, sunlight, and little wind, and the difference becomes even more noticeable. Your body is working overtime to keep itself cool while also powering your run. That extra workload often means your pace naturally slows down. This doesn't mean you're getting slower. It means you're running in more challenging conditions. Adjust Your Pace, Not Your Expectations At Runcoach, we believe pace is one of the most valuable training tools available. Pace helps provide structure to workouts and ensures you're training in the appropriate effort for your goals. However, pace should always be viewed within the context of the conditions. Think of your training paces as targets, not rigid requirements. When temperatures climb, experienced runners adjust their expectations rather than forcing splits that no longer match the environment. The goal is still to complete the intended workout. Sometimes that requires making small adjustments to the pace displayed on your watch. How Much Should You Adjust? There is no perfect formula because every runner responds differently to heat. Factors such as humidity, sun exposure, fitness level, and heat acclimation all play a role. As a general guideline:
The key is recognizing that these changes are normal. If you're consistently running slower in July than you were in April, that doesn't automatically mean your fitness has declined. Don't Chase the Watch One of the quickest ways to turn a productive run into a miserable one is to force a pace that doesn't match the conditions. Many runners become so focused on hitting a specific number that they ignore what the weather is asking of them. A better approach is to use your pace target as a guide while allowing for reasonable adjustments when conditions are difficult. Some days you'll hit every split perfectly. Other days, the smartest decision is backing off slightly and completing the workout successfully. Consistency beats forcing one workout and needing extra recovery afterward. Expect an Adjustment Period The good news is that the body adapts. Heat acclimation typically begins within the first week of consistent exposure and continues to improve over roughly two weeks. As adaptation occurs, several positive changes take place:
Many runners notice that workouts begin feeling easier after 10 to 14 days of training in the heat. The key is patience. The first few hot runs of the season are often the most difficult. Summer Fitness Pays Off Later Here's the part many runners forget. The work you're doing now is still building fitness. Even if your watch shows slower paces, your body is adapting to the demands of training in tougher conditions. When cooler temperatures return in the fall, many runners are surprised to see their pace improve almost immediately. The fitness was there all along. The weather was just hiding it! This is one reason so many marathoners and half marathoners complete the bulk of their training during the hottest months of the year. The miles you log in June, July, and August often show up as stronger performances in September, October, and November. A Few Summer Running Tips To make summer training more manageable:
The Bottom Line If your pace is slower this summer, don't panic. Heat and humidity affect every runner, from beginners to elite athletes. Adjusting your pace for the conditions isn't a sign of weakness, it's a sign of smart training. Stay consistent, trust the process, and remember that the goal isn't to win a workout in July. The goal is to build the fitness that will help you perform your best when race day arrives. And when those cool fall mornings finally return, you'll be glad you kept showing up.

This year marks an incredible milestone for Coach Rosie as she celebrates five years with Runcoach. Over the past five years, Rosie has helped countless runners and walkers achieve goals they once thought were out of reach. From first-time finishers to seasoned marathoners, her thoughtful coaching approach, attention to detail, and genuine passion for helping others have made a lasting impact on the Runcoach community. To celebrate her five-year anniversary, I sat down with Rosie to reflect on how the running world has evolved, what she's learned along the way, and some of the athletes who have inspired her most. Rosie: The two biggest advancements I've seen are definitely carbon-plated shoes and high-carbohydrate fueling strategies. The impact of carbon-plated footwear on performance is undeniable, but if I'm honest, it's the evolution of fueling that fascinates me most. We're learning so much more about how athletes can properly fuel before and during training and racing, and it's completely changing the marathon experience for many runners. I love helping athletes work through the trial-and-error process of finding what works best for them. When you see someone successfully execute their fueling plan and avoid hitting the wall in a marathon, it's incredibly rewarding. Q: What has changed most for you personally during these five years?Rosie: Last year I became a mom, and that has been the biggest change of all. The arrival of my son, Leo, has completely transformed my life. It's been an amazing journey, and it's given me a new perspective on both running and coaching. I'm still pursuing my own competitive goals, but now I have the added motivation of seeing him waiting for me at the finish line. Q: What do you enjoy most about coaching through Runcoach?Rosie: Without question, it's watching athletes exceed their own expectations. Many runners start with goals that feel intimidating or even impossible. What I love is seeing them consistently show up, trust the process, and gradually chip away at those goals. Then one day, something that once felt unattainable becomes reality. Seeing the confidence and satisfaction that comes from achieving a goal you've worked hard for is one of the most rewarding parts of coaching. Q: Is there a particular athlete story that stands out?Rosie: There are so many, but one athlete who immediately comes to mind is Paul Nolan. Paul competes in the 70-74 age group and completed marathons on six different continents last year. That's impressive enough on its own, but what makes his story special is who he is outside of running. Paul is a devoted father who learned Mandarin after adopting his daughter, and now the two of them often travel together to races around the world. Watching him continue to pursue ambitious goals while sharing those experiences with his family has been incredibly inspiring. Thank You, Coach RosieFive years of coaching means five years of early-morning race nerves, breakthrough workouts, marathon celebrations, setbacks overcome, and countless finish-line moments shared with athletes around the world. Coach Rosie has been an invaluable part of the Runcoach team, and we're grateful for the expertise, encouragement, and care she brings to every athlete she works with. Congratulations on five amazing years, Rosie. We can't wait to see what's next.

Get to Know the Coaches - Oustside of Running
Decoding Your Unique Smart Watch Metrics: Why YourMay 27, 2026If you run with a modern sports watch, you’ve probably noticed that we are living in the golden age of running data. After a solid long run, your Garmin Connect app serves up a buffet of advanced scientific metrics. But what do all those numbers actually mean for your daily training? I’ve started to consider what this data might have meant in my faster days (late ‘90s and early ‘00s). At the time, there were limited metrics available aside from a handful of high-end biomechanics labs. The data presently at our finger tips, coming from our wrist, on a daily basis is both pervasive and awesome (in the fear inspiring sense). For years you’ve heard me and our other coaches stress the importance of pace recognition, Rate of Perceived Exertion which we use as Rate of Perceived Effort (RPE), progressive pacing with some input from heart rate as a % of maximum heart rate. I’m super excited about all the new data available and believe that proper pacing with recognition along with forms of progressive pacing are still the most important for race and training outcomes. But. . . the available data can no longer be ignored so let’s start to interpret some of it. Today, we’re going to look at three of my favorite advanced running dynamics:
I’ll explain what they are, why they matter, and how we can tweak your form/effort to become a smoother, more efficient, and injury-free runner. Note: Definitions from Garmin Human Performance Lab are publicly available and included below. Stride LengthThis is simply the distance you cover with each stride. Of course, we don’t want long lopey strides or potential over striding to interfere with our focus. In fact a shorter stride length can be beneficial especially in the early parts of a race. One practical consideration I have with stride length is to consider your drive at the end of races. Often we observe max stride length at 75-85% of race distance. One way to improve the stride length is a concomitant effort to swing your arms with strong force near the end. If you watch World Class Marathon/10K/5K/1500m etc. runners at the finish their arm swing is almost always exaggerated compared to the start of the race. When you swing your arms with force, your legs follow suit. What is Vertical Oscillation?In simple terms, Vertical Oscillation is your "bounce." It measures the amount of vertical movement in your torso with each step, measured in centimeters. Ideally, as runners, we want our energy propelling us forward, not upward. However, we frequently see a point of frustration for taller runners here. Because taller runners have longer legs and naturally longer strides, their absolute vertical oscillation numbers are almost always slightly higher than shorter runners simply due to biomechanics. A tall runner might naturally sit around 7.5 to 8.6 cm, which can look high on paper but is perfectly normal for their height. In my opinion, raw Vertical Oscillation metrics should not be over emphasized. Stride length (especially at the end of a good effort) + Vertical Ratio are better indicators of proper form. The Great Equalizer: Vertical RatioIf you’re a taller runner looking at your Garmin data and feeling discouraged by your bounce, don't worry. This is where Vertical Ratio comes to the rescue. Vertical Ratio takes your Vertical Oscillation and divides it by your Stride Length, expressing the result as a percentage. This metric essentially levels the playing field, factoring in your height and stride to give you a true picture of your running efficiency. Instead of obsessing over raw centimeters, look at your Vertical Ratio percentage. Here is how the benchmarks break down:
(Note: Many runners find they naturally bump up against "Excellent" or "Great" ratios during fast interval sessions, as faster running promotes better form! This is one of the reasons that here at Runcoach we always suggest one or two quality sessions with intervals at faster paces each week.) Why Does Your Bounce Matter?Whether you're a middle-aged marathoner or an infrequent 5K racer, keeping your Vertical Ratio in check provides two massive benefits: 1. Energy Conservation Think of it this way: over the course of 26.2 miles, bouncing an extra inch per step equates to climbing hundreds of extra feet of elevation. By keeping your bounce down, you are saving precious glycogen stores for the later miles when you really need them. 2. Injury Prevention What goes up must come down. A higher vertical oscillation means a heavier landing. Reducing your bounce significantly decreases the ground reaction forces on your knees, hips, and lower back. If you want to stay healthy and injury-free through long, grueling training blocks, smoothing out your ride is key. How to Improve Your NumbersIf your watch is consistently showing a high Vertical Ratio, you don't need to completely overhaul your stride. Usually, corrections only need to be made in millimeters. Here are 5 practical, coach-approved ways to smooth out your ride:
The Bottom LineAt Runcoach, we believe data is only as good as the human insight behind it. The next time you finish a run, take a peek at your Vertical Ratio in Garmin Connect. If the number is a bit high, try running "quietly" with a slightly quicker step on your next outing. Check out your Vertical Ratio on the intervals of your quality sessions and you will see a big difference. Want a coach to look at your smart watch and help you build a plan to improve your running economy? Our 1:1 human coaching team is always here to help you make sense of the metrics and achieve your next personal best.

Marathon Race Weekend: Final InstructionsMay 27, 2026The hard work is done, and your reward is race day itself. These final instructions will help you navigate the weekend, manage your energy, and conquer the course. First and foremost: lay low and stay off your feet. Limit your time at the race expo to no more than an hour. 1. Pre-Race Arrival & Mindset
2. Fueling & Hydration (The Night Before to the Starting Line)
3. Prepare for the Elements
4. Pacing the Early MilesPatience early on pays huge dividends later. The goal is to conserve glycogen and muscle strength for as long as possible while activating fat as a fuel source early in the race.
5. Remember the 3 C’s
6. The Ebb and FlowI can guarantee one thing: you will feel terrific at some points and terrible at others. Marathons always ebb and flow. When you hit a wall, stop thinking about the finish line. Focus entirely on the next mile. Remember walk breaks provide intermittent relief and I’ve witnessed 2:20 marathon runners use brief walk breaks to regroup. If you take the difficult moments one mile at a time, some good feelings typically return. 7. You Always Have One Cup LeftWhen the race gets incredibly tough, remember that you always have one cup of energy left—the difference is whether you choose to find it. When normal, untrained people feel discomfort, they slow down so they can feel better. You are not an untrained person. You are a marathon machine. At the end of the race, you will have to dig deep to determine if you will cross the finish line with an effort you can be completely satisfied with. Go get that last cup!

Racing
Something shifted this spring - and it wasn’t just the weather. At the Boston Marathon, we saw fast times across the board. Some pointed to ideal conditions - and that’s always part of the story. But then came the London Marathon. No tailwind. No excuses. Just historic performances. Sebastian Sawe ran 1:59:30. So what connects Boston and London? It’s not just talent. It’s not just shoes. It’s fueling. The Carb Revolution Is No Longer a Theory For years, endurance athletes were told to limit carbohydrate intake or “train low.” That thinking has flipped - completely. At the elite level, the focus now is maximizing carbohydrate availability in both training and racing. Here’s what we’re seeing:
This isn’t marginal gains anymore. This is a fundamental shift in how endurance performance is built. Fueling Is Driving the Training The real breakthrough isn’t just what’s happening on race day - it’s what’s happening in training. Higher carbohydrate intake allows athletes to:
Instead of digging a hole with every hard session, runners are actually supporting the work required to improve. That’s a big shift. Fitness is no longer limited by how much discomfort you can tolerate - it’s supported by how well you fuel. Why This Changes Everything This isn’t just about elites running faster times. It’s about why they’re running faster. When fueling improves, everything downstream improves:
We’re seeing it across the board - marathoners, triathletes, cyclists. Better fueling leads to better training. Better training leads to better performance. What This Means for You No, you don’t need to jump straight to 120-150g of carbs per hour. But the direction is clear:
The key is doing it correctly for your body and your training. The Bottom Line We’re entering a new era of endurance performance. Records that once felt untouchable are starting to fall - not because athletes suddenly got more talented, but because they’re finally fueling in a way that supports their potential. High carbohydrate fueling is leading that shift. And for the first time in a long time, performance gains are coming from something that also supports better training consistency and long-term development. That’s a change worth paying attention to.
