I Blew Up Mid-Race — Still Smashed a 10K PB (What I Learned)

Video Description

💥 I SMASHED MY 10K PB... BUT IT NEARLY FELL APART I went out too hot (3:37 surge at K3), drifted too far over threshold — and paid for it. But somehow, I still hung on for a 37:56 PB (–1:14) and learned everything I need for marathon day discipline. This is the full race-day story — the pacing plan, the blow-up, the mental battle, and the lessons I’ll carry into my sub-3 marathon build. WHAT’S INSIDE • Perfect start — 3:40 / 3:41 • The 3:37 surge that lit the fuse • Why “feelings lie” early in races • Conditions that quietly stack up (heat, rollers, extra distance) • The mental fight when the goal’s slipping away • Data vs no-data racing — what I’ll change next time • Lessons for marathon pacing & decision-making DETAILS Race: WAMC Col Junner 10K (Tune-Up) Result: 37:56 (PB by 1:14) Goal: Sub-3 Marathon (2:57 target — Perth Running Festival) Training: Norwegian Singles – 9-week block Training: Norwegian Singles (high-frequency sub-threshold) Paced by: @SotaMaehara Every race is feedback. Every setback is a lesson. This one gave me both.
