Your estimated time on each race
Calculated at your UTMB Index, by the same formula as your RAVIT plan.
Effort-km = km + elev. gain/100 · categories XXS to XXL by effort-km · minimum speed = distance ÷ time limit.

Ranking glossary
- Effort-km
- Distance in km plus elevation gain divided by 100: 50 km and 2,500 m of gain equals 75 effort-km. Categories: XXS under 25, XS 25 to 44, S 45 to 74, M 75 to 114, L 115 to 154, XL 155 to 209, XXL 210 and above.
- Gain/km
- Elevation gain divided by distance, in meters per kilometer: the lower it is, the more runnable the race.
- Time limit
- The maximum time allowed by the organizer to reach the finish, the final cut-off time.
- Minimum speed
- Distance divided by time limit, in km/h: the average pace to maintain to finish within the deadline. The lower it is, the wider the cut-off.

How many M races publish a time limit?
112 out of 124. The others show « unknown » and fall to the end of the minimum speed ranking.
Why rank by effort-km rather than distance?

Method and sources
Data updated October 31, 2026, covering 124 2027 races in the RAVIT catalog.
- Distance, gain, date, country and time limit: sourced from each race organizer's website, and utmb.world for UTMB World Series events; each entry cites its source.
- Categories XXS to XXL: calculated by RAVIT using effort-km (km + gain/100), at the thresholds shown above.
- Minimum speed: distance divided by time limit. A race with no published time limit displays « unknown » and sorts to the end.
- Aid stations: the number of documented aid stations on the race's RAVIT entry; « unknown » when none are yet documented.
