ACAT Climbathon: 100 climbs in 4 weeks – take the challenge!

The ACAT Climbathon is a nationwide fundraising and participation event throughout April 2026 bringing climbers together to take action for access. 

Climbers can challenge themselves to complete 100 climbs and raise $20,000 to power ACAT’s work. Whether you boulder, sport, trad, or alpine climb, it’s a simple idea with powerful impact: climb, connect, contribute.
