You are on your own! HAWC25 is not an organized race with race marshals, samaritans and depots. We try to determine who is the best climber in the world by facilitating timing and compile leaderboards to determine winners.

• You must be entirely self-supported
• Only time on the three climbs count towards the leaderboard
• Take it easy on descents (and be extra careful from the top of Sabot!!)
• Always adhere to local traffic rules

The High Altitude World Championships (HAWC), introduced in 2024, have quickly gained recognition as a unique event in the cycling world. This competition challenges cyclists to complete a high-altitude course within a time limit, entirely self-supported. Unlike typical races, only the times recorded on designated climbing segments contribute to the overall standings. A distinctive feature of the HAWC is that all these climbs occur on cols situated above 2,000 meters, adding an extra layer of challenge due to the demanding altitude.
