A sub-4:00 marathon requires a half marathon baseline. An official race provides the finishing time that predicts marathon capability and, more importantly, the race experience — fuelling strategy, pacing in crowds, and late-mile fatigue — that solo training runs cannot replicate. Target time: 1:45–2:05 indicates genuine sub-4h marathon potential.
Proof required
Submit your official half marathon chip time from a registered race. Acceptable sources: official race results URL showing your name and chip time, a finisher certificate from the race app, or a race bib photo alongside the official results page. GPS watch time from a solo run is not accepted for this milestone.
What gets checked
- Official chip time from a registered half marathon race — not a solo GPS run or a 'virtual race' unsupported by a race organisation
- Race name and date are visible in the evidence
- Time is plausible as a sub-4h marathon predictor: finishing times up to 2:20 are realistic for someone early in their marathon training
