Sources and method
- Time projection — for lack of results on this race, times by UTMB Index rely on a Riegel law whose exponent is adjusted to elevation gain — the model's fallback, not its usual method. Peter Riegel (Wikipedia)
- Trail nutrition — hourly targets for carbohydrate, fluid and sodium follow the commonly accepted ultra-endurance guidance. La Clinique du Coureur — Fuelling in trail running
- Course, aid stations and cut-offs — taken from the event's official rules, which prevail in case of any discrepancy. Official site — Marysville 100
