Sierra Summer Challenge

Go the distance for adaptive mountain sports in the Eastern Sierra. The Sierra Summer Challenge is back — and this year, we’re inviting our community to help Move Mountains Together. From July 5–19, participants from across the country will hike, bike, paddle, climb, walk, roll, swim, garden, or create their own challenge in support of adaptive recreation and inclusion through Access Mammoth. This peer-to-peer fundraiser is designed for every body and every ability level. Whether you’re logging miles on the trail, taking daily walks with friends, or challenging yourself to something new, every activity helps create access to life-changing outdoor experiences for individuals with disabilities. Every dollar raised supports: Join as an individual, create a team, or support a participant from wherever you are. Together, we can help more people experience the freedom, confidence, joy, and connection that come from outdoor adventure. Our 2026 fundraising goal is $175,000 — and every mile, every post, and every donation helps move us closer. Because access doesn’t happen by accident. It happens when communities move mountains together. Not able to participate? You can still make a difference—donate today and help us keep mountain sports accessible to everyone.
