From 3:21 to Sub 3… in Zone 2

Why the First Rep Always Feels the Hardest

If rep one always feels like your hardest rep, your warm-up failed before the session started. Most runners jog a couple of easy miles, stop, then wonder why they don't arrive until rep three.

This Summer Will Break You — or Build You

The Pace Trap: the reason your marathon paces fall apart the moment it gets hot — and it isn't the reason you think. If you're chasing sub-3 or sub-3:30 and your summer paces have slipped, you've probably decided you're losing fitness. You're not. Here's what the heat is actually doing to your watch, why the number is lying, and the one thing to anchor to instead. In this video: - Why heat slows your pace at the same effort — physics, not lost fitness - The problem with heat pace-adjustment charts, and what to anchor to instead - How to compare a summer session to a spring one without fooling yourself - What heat training quietly banks for a cool race day - Heat vs altitude: the most underrated free tool you have - What Western States 2026 showed about chasing the number 00:00  It's July and your pace just fell apart 00:32  Why heat breaks your pace (the physics) 01:29  The pace-chart trap 02:49  The race that taught me this 04:29  The fix: anchor to effort, not pace 07:03  How to compare summer and spring sessions 08:47  Banking heat adaptation 10:01  Proof at 100 miles: Western States 10:21  Trust the process Book a Performance Strategy Call — a free 15-minute call to map where you are and how to get to your goal: https://coaching.allin.run/book-psc All In Performance Coaching helps committed marathoners — mostly working professionals chasing sub-3 and sub-3:30 — train with the precision usually reserved for elites.

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?

Stop Adding Hard Sessions — Repeat This Instead

You don't need to repeat harder sessions. You need to repeat the boring ones. If you're a serious marathoner who keeps adding the next big workout and still plateauing — this is why. Here's the simple week that built every result I've ever coached, repeated for months. 📞 Ready to have a real marathon breakthrough? Book a free 15-minute Performance Call to see if there’s a coaching fit: https://coaching.allin.run/repeat The runners who improve aren't the ones with the most impressive sessions. They're the ones who repeated a simple week — consistent aerobic volume, one threshold day, one long run — for six to twelve months. This video breaks down that week, why “more hard work” caps you, and how I went from 3:25 and a failed sub-3 to 2:21 by doing less, repeated.
