The Grey Zone Is Why You've Stopped Getting Faster

2026-08-2614:43

You have been running consistently for years and your marathon time has not moved. That is almost never your ceiling — it is a purpose problem. Every run has quietly become the same run: a little too fast to recover from, nowhere near fast enough to improve anything. That zone has a name. This video is what it is costing you, how to tell when you are in it, and what to do instead. In this video I cover the endurance triangle and where your marathon time actually comes from, why the same ...

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

2026-08-0615:55

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 whethe...

Why 3 Minutes Can't Predict 3 Hours

2026-08-0209:10

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 a...

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

2026-07-2809:57

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 cont...

He Took 21 Minutes Off His Half Marathon — No Taper

2026-07-2308:18

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, ...
