    You're training too hard. 8 out of 10 Breaks 45 for 10K

    Most runners chasing a sub-45 10K finish every interval session at ten out of ten. That is exactly why they stay stuck at 47, 49, 51 minutes. This is the eight-out-of-ten rule: nine kilometers of work, four sessions, and six months of progression without ever telling yourself to run faster. If you are between 52 and 46 minutes for 10K right now and you want to break 45, start here. And once 45 goes, sub-40 is closer than you think. Book a 15-minute call, and I will tell you honestly whether your training is attacking the right thing, and whether coaching with me is the right way to close the gap: https://coaching.allin.run/sub45 THE LADDER 6 x 500m — 8 x 500m — 10 — 12 — 14 — 16 — 18 x 500m Then hold the 9km and change the shape: 500m — 1km — 1.5km — 3km 60 seconds walk recovery throughout.

    Why 3 Minutes Can't Predict 3 Hours

    Sub-3 marathon training is full of tests that promise to predict your finish time. The most famous of them never asks you to run for more than three minutes without stopping. Ten times 800 meters. Three minutes a rep, three minutes jogging, and you are told that is your marathon. This video shows why the arithmetic behind that cannot work – and gives you the two sessions I use instead, both at the same pace, both answering a question a three-minute rep cannot reach. If you want me to look at where you actually are, and what is realistically on the table this cycle, book a Performance Strategy Call: https://coaching.allin.run/800 **THE TWO SESSIONS** Both sit at 94% of goal marathon pace. That is a smaller margin than the 800 session asks for, and a far harder question. A sub-3 marathon is 4:16/km or 6:52 per mile – the marker asks you to hold 4:00/km, 6:26 per mile, for sixty minutes. **WHO THIS IS FOR** Runners chasing a sub-3 hour marathon or a sub-3:30, who want to know whether the goal is realistic before race day rather than at 35km. The same marker scales to any goal time – the table at 7:25 gives the pace and the distance for 2:45 through 4:00. **CHAPTERS** 0:00 Why 3 minutes cannot predict 3 hours 0:42 The three sub-3 tests you will be handed 1:49 Where the 800m marathon predictor came from 3:23 Why it gives every runner the same answer 4:38 What a three-minute rep cannot see 5:22 The two sessions I use instead 6:34 Your hour, whatever your goal time 7:04 Testing without wrecking your marathon block 8:07 What the marker does not promise **ON THE SOURCES** The 800m session originated in the mid-1980s as one runner's observation of his own training, written up in a Runner's World column around the turn of the century. Its creator has described the pattern as a coincidence he happened to notice. In thirty years, no study has tested it against a cohort's marathon results. The criticism is not new either – the recovery length was being questioned publicly in 2005. All In Performance Coaching – marathon coaching for runners chasing sub-3:00 and sub-3:30.

    He Ran a 1:36 Half. Six Weeks Later: 2:57 Marathon

    He ran a 1:36 half marathon. Six weeks later: a 2:57 marathon — double the distance, nearly forty seconds per mile faster. Every race calculator says that cannot happen. It predicted 3:22. Here is why it was wrong, and why it might be wrong about your autumn marathon too. Race predictors assume two things: that your half was a maximal, tapered effort, and that the runner on marathon day is the same runner who raced it. Neither was true. His half was a checkpoint — placed mid-block, run controlled on trained legs, back in normal training the next morning — and he was improving every week on a plan built around his limiting factors, not a generic template. In this video: why calculators misread runners on an upward trajectory, the checkpoint half that reveals real marathon readiness, five athletes who broke their predictions by 19 to 55 minutes, the signs your training is attacking the right targets, and why years of running experience did not predict any of it. Book a Performance Strategy Call — 15 minutes, bring your training, and I will tell you honestly whether it is attacking the right things, and whether coaching with me is the right way to get you on that trajectory: https://coaching.allin.run/checkpoint 00:00 A 1:36 half, then a 2:57 marathon 00:27 Why every marathon prediction was wrong 02:10 A plan built on your limiting factors 03:24 The checkpoint half: pacing on tired, trained legs 04:22 Five athletes, one pattern 06:00 Signs your marathon training is working 06:56 Years of running experience didn't matter 07:45 From a 1:41 half to sub-3? 08:53 Have you been training the right way? #marathontraining #sub3marathon #runningcoach

    He Took 21 Minutes Off His Half Marathon — No Taper

    He took 21 minutes off his half marathon in one training block — no taper, tired legs. If your marathon is this autumn, you are exactly where he is: 13 weeks out. This is the method. This runner had never raced. His half marathon best was 1:52, run alone in training. One block of structured, individualized marathon training later, he ran 1:31 — nearly 19% faster, almost a minute per kilometer — and this weekend he repeated that time on loaded, trained legs in the middle of a marathon build, without tapering once. In this video: why "run as fast as you can for as long as you can" training stalls, how a plan built around your limiting factors changes every session, the pacing skill that removes race-day anxiety, the fatigued-state half marathon that proves marathon readiness, and what the final 13 weeks of a marathon block are for.

    25 Minutes to Sub-20: The 5K Plan Nobody Explains

    If you can run 5K in 25 minutes, sub-20 is closer than you think — but only if you do it GRADUALLY. The plan itself is simple. What nobody explains is the bits around it: how often you run the session, what the rest actually is, and what to do when it falls apart.

    Stop Racing Your Training

    There's a clock at the finish line — so you've become obsessed with the pace on your watch. That obsession is the exact thing keeping you slow. If you're chasing sub-3 (or a sub-40 10K) and hammering goal pace in every session, you're probably racing your own training. This is why the approach that got you here won't get you further — and what actually moves you now. Most runners chase a pace. They pick a goal number and go after it in every session, regardless of the day, the weather, or how they feel. It works for a while — it's how you get from four hours to three-oh-five. And then it stops, because the closer you get to your ceiling, the more it matters which limiter is actually yours, and a one-size plan can't know that. Here's the physiology that changes it: your heart rate is the cost, your pace is the output. Fitness doesn't teach you to hold a higher heart rate — it teaches the same heart rate to run faster. Chase a pace above your threshold, session after session, and you're not raising the ceiling — you're just visiting the place you can't stay, arriving at the sessions that matter with dead legs, and building the injury that actually keeps you stuck. The fix is to stop forcing the number. Train to effort, build the base, get strong, and let the pace come to you — so it turns up fresh at 26.2 instead of blowing up at 20. This applies just as much to the 10K as the marathon.

    You Didn't Get Slower. You've Been Training Wrong.

    You didn't get slower with age. You've been training the wrong way — and that's fixable. If you're chasing sub-3 or sub-3:30 and your paces have stalled, you've probably decided it's your age. It almost never is. This breaks down what actually changes after 40, what doesn't, and why most plateaus are a training problem, not a ceiling. Most men over 40 blame their age for missing sub-3. In my experience coaching runners, it's almost never the age. One thing does fade — the very top of your engine, your VO2max. But the things a sub-3 marathon actually runs on — your lactate threshold, your efficiency, your ability to hold pace deep into a race — barely age at all. And even that engine decline is mostly detraining, not biology. There's a reason most runners plateau for years: they're not at the limit of their body, they're at the limit of their method. Fix the training, and the breakthrough that follows is real. This video covers what changes after 40, the numbers sub-3 actually demands, and the shift that decides whether you get there.

    Your 5K Says Sub 3 — Your Marathon Says No

    An 18:30 5K should mean a comfortable sub-3 marathon. Every race-time calculator is certain of it. So why do so many fast 5K runners keep missing sub-3 — while runners who can't break 19:30 run it every single time? This video shows you what your 5K actually measures, why the marathon rewards something completely different, and the one change to your Saturday that builds more marathon fitness than chasing a parkrun PB ever will. If you are a time-poor runner with a job, a family and a marathon goal, this is how to use the few hours you have — and why your slow 5K is almost certainly underselling you.

    Your Interval Session Is Two Workouts in One

    Your VO2max session and your threshold session can be the exact same workout — 8×1K off short rest. What decides which one you actually get is how you run it. Most committed marathoners are training one when they think they're training the other — and it shows up in the back half on race day. Here's the dial, how to build it, and the one question that matters more than reps or pace: what's actually holding YOU back. Leandro asked a great question: he's about 12 weeks from his marathon, running 8×1km off 60 seconds, and wants to know whether to add reps (10×1km) or make them longer (5×2km). The honest answer is that neither is the decision that matters — because the same session can be an easy run, a threshold session, or a VO2max session depending on nothing more than how hard you run the reps. In this one I break down how to turn 8×1km into the session your marathon actually needs: how to progress it without running too fast (the #1 mistake I see in 2:30–3:30 marathoners), why your lactate threshold — your one-hour race pace — is the single best predictor of marathon success, how much VO2max a sub-3 marathon really takes (less than you'd think), and how to pace the race itself. The thread running through all of it: until you know your own limiter, every plan is guesswork. ⏱️ CHAPTERS 0:00 8×1km Intervals: More Reps or Longer? 0:54 Same Session, Two Workouts (VO2max or Threshold) 1:32 How to Progress the Session Without Running Too Fast 2:50 The #1 Predictor of Marathon Success: Lactate Threshold 3:16 Turn 8×1km Into a Threshold Session 3:53 What's the Purpose of This Session? 4:23 How Much VO2max You Really Need for Sub-3 4:58 Push Your Threshold Right (LT1 & LT2) 5:44 How to Pace a Sub-3 Marathon 6:33 It Depends on Your Limiter 7:26 Train Smart, Not Just Hard 🎯 WORK WITH ME Chasing a sub-3 or sub-3:30 marathon this autumn — New York, Chicago, Berlin or anywhere else — and want the best possible result from the training time you've got?

    How to Train for a Sub-90 Minute Half Marathon

    A sub-90 half marathon isn't won on your hard days or your easy days — it's won in the middle, at threshold, the work most runners skip. If you're running 1:32–1:50 for the half now and want to break 90 (and one day break 3 hours), you're probably training in two speeds. Here are the two sessions that fix it, why sub-90 shows up as a byproduct of sub-3 marathon training, and the 5K Check that tells you where you stand today. Most runners chasing a sub-90 half marathon train at two speeds: flat out on hard days, long and slow on easy days — and skip the threshold work in the middle that actually decides the race. That gap is exactly why they fade in the final 5K. Sub-90 (4:16/km · 6:52/mile) isn't a speed problem or an endurance problem. It's a threshold problem. 2:21 marathoner and UK 100km Champion Lee Grantham — the coach behind All In — breaks down the two sessions that build the middle (sub-threshold intervals and a progressive, race-specific long run), why the same engine that wins a sub-90 half is the one that carries you to a sub-3 marathon, and the 5K Check that tells you whether sub-90 is one block away or an engine away.

    Sub-3 Marathon: The 2 Numbers That Prove You're Ready

    Are you ready to run a sub-3 marathon? Before you commit to a sub-3 training block, there are two numbers that tell you you're ready — not nearly ready, ready. The first: a solo 10K time trial in 40 minutes. The second: holding 4:00/km (6:26 per mile) for a full hour — a 15K in 60 minutes, or a 10-mile race in about 64. I break down the exact sessions to build both, why I coach to effort instead of pace, and how one runner went from 3:21 to a 2:56 first sub-3 in Chicago. These are indicators, not goals — hit them on an upward curve and you're one or two training blocks from your Boston qualifier. 📞 Ready to chase your sub-3?

    Same Heart Rate, 2 Min a Mile Faster — How This Marathon Runner Did It

    Same heart rate. Two minutes a mile faster. Twenty-two weeks apart. This is what a real marathon training breakthrough looks like when you stop chasing paces and start training the engine. If your watch keeps showing you the same paces no matter how hard your heart is working — this marathon training breakthrough is for you. 📞 Serious about a real breakthrough? Book a coaching match call with Lee: https://coaching.allin.run/same-hr-2min 🔔 Subscribe for weekly marathon training videos: https://www.youtube.com/@leegrantham?sub_confirmation=1 📲 Instagram: https://instagram.com/leegrantham ━━━━━━━━━━━━━━━━━━━━━━━━━ ⏱ CHAPTERS 0:00 Same Heart Rate, Two Minutes a Mile Faster 0:48 Where He Actually Started 1:50 Train the Engine, Not the Paces 2:55 The Two Efforts That Decide a Marathon 3:25 Why Easy Days Are Too Fast for Most Runners 4:25 Race Day Where Most Marathon Blocks Fall Apart 5:30 How He Negative Split the Marathon 6:38 Coaching Match Call With Lee 7:00 Why Reasonable Goals Are the Wrong Target ━━━━━━━━━━━━━━━━━━━━━━━━━ 📺 WATCH NEXT ▶ Half Marathon Tune-Up for Sub-3 Marathon: Best Workout or Biggest Mistake? https://youtu.be/BsbtfWqlui0 ▶ Most Runners Get Zone 2 Wrong Without Realizing https://youtu.be/oUnyfAN21fk ━━━━━━━━━━━━━━━━━━━━━━━━━ ABOUT THIS MARATHON TRAINING BREAKTHROUGH How one coached runner took 56 minutes off his marathon PB in 22 weeks — same heart rate, two minutes a mile faster. He's not a genetic freak. He's a busy man with a demanding job, a young family and another baby on the way, who started on about four hours of training a week and finally had a plan that fit his life. Like most runners, he had the engine of an athlete and the pacing of a beginner: easy runs too fast, hard runs never hard enough, every day stuck in the same grey zone. The fix wasn't a secret workout. It was heart-rate training that respects what the body is actually doing, the two efforts that decide every marathon trained properly, and the discipline to repeat an unglamorous week until the paces came down on their own. 2:21 marathoner and UK 100km Champion Lee Grantham — the coach behind All In — breaks down exactly how it happened: why heart rate tells the truth when pace lies, why your easy days are probably too fast, how the two efforts that decide a marathon need to be trained, and how race-day pacing turns a marathon from survival into a negative split. Along the way the runner also hit a half marathon PB and a 10-mile PB — the marathon training plan was producing breakthroughs across distances. These are the marathon running tips and structural principles that produce every real marathon training breakthrough — same heart rate, two minutes a mile faster. If you want to know how to run a marathon at your true potential — chasing a sub-3 marathon, a Boston Qualifier (BQ) marathon, a sub-3:30 marathon goal, or breaking through a marathon plateau — heart rate training and the right marathon training plan matter more than mileage volume. Train the engine, not the watch. Make easy days truly easy. Make hard days specific. Repeat the unglamorous week after week. The numbers come down as a byproduct. Same heart rate. Two minutes a mile faster. Twenty-two weeks apart. ━━━━━━━━━━━━━━━━━━━━━━━━━ ABOUT LEE GRANTHAM — MARATHON RUNNING COACH Marathon coach, UK 100km Champion, 2:21 marathoner, with 18 marathon wins and course records at Pico Veleta 50km (×2), Doi Inthanon 50km and Doñana Trail 71km.

They come from precision, structure, consistency, and training that actually fits the individual runner. In this case, a runner was told “no chance” at sub 3 marathon, and just seven weeks later improved from 44:05 to 38:44 for 10K. That level of improvement is not luck. It is what happens when marathon training, 10K training, and running structure finally align with the athlete. Most runners stay stuck because they follow generic training plans, listen to negative opinions, and chase round-number goals like sub 3 marathon that actually limit their ceiling. Real progress in running comes from asking better questions, building the right system, and applying the right effort at the right time. If you want to run faster, improve your 10K time, break through a plateau, and unlock your true marathon potential, you need clarity, precision, and consistency — not more guesswork or motivation. #RunningTips #MarathonTraining #10KTraining #Sub3Marathon #runfaster Music track: Back in Time by Aylex Source: https://freetouse.com/music Royalty Free Background Music

    2-Hour Marathon Broken: Here's What Actually Happened

    The 2-hour marathon barrier has been broken in a real race — but what actually changed? In this video, I break down what really happened when two men went under 2 hours at the London Marathon, why this moment is so important, and what it reveals about marathon racing, fatigue, competition, and human limits.

In this video, you’ll learn: * what made this sub-2 marathon breakthrough so different * what the Breaking2 and INEOS efforts were missing * why race day can unlock levels that training should not * how fatigue changes heart rate, effort, and performance * what this means for your own marathon potential * why the marathon is ultimately a test of character If you want to understand marathon performance at a deeper level — and what the 2-hour marathon means for everyday runners — this video will show you exactly that. 📞 Ready to PR your next race?
