Ultramarathon: how far, how to prepare and what really matters
Any race longer than the marathon distance of 42.195 km is an ultramarathon. Flat 50 km races and steep 100 km mountain routes are very different challenges.
FIRST-HAND EXPERIENCE
50+ ultramarathon finishes. Experience racing for up to 30 hours and completing mountain ultras longer than 100 km with over 8,000 m of elevation gain. Race stats come from my personal journal; the full race archive is being expanded.

Training for long-distance demands
Build consistent running habits and recovery before increasing long runs. Training should reflect current ability, expected time on feet, and the course rather than chasing a single weekly mileage target.
Fuelling and hydration
Practice drinking and eating during long training outings. At Rosa Wild Trail 2025, my nutrition problems turned an early lead against the checkpoint plan into a significant delay later in the race.
Pacing a mountain ultra
Steep climbs often call for brisk walking; descents require strong legs and concentration. Planning realistic splits by checkpoint is usually more useful than choosing one average pace.
