Colorado Challenge Series
The Colorado Challenge Series is a collection of four high‑intensity physical fitness events designed to push your limits while supporting veterans and their families. Participants who register for the full Series earn the exclusive 2026 Colorado Challenge Series Medal, awarded only to those who complete all four events. This is the ultimate Colorado fitness challenge uniting endurance, community, and charity to make a real impact for those who served.
It consists of four events, and participants that complete all four events within the required time constraints qualify to earn the CO Challenge Series medal!

We believe every athlete deserves a place in this mission. For participants with adaptive or accessibility needs, we are proud to partner with the Break Your Neck: Walk, Run, or Roll 5K/10K, a sister event that offers an inclusive pathway to join the Challenge Series community. This partnership ensures that athletes of all abilities can take part, push their limits, and contribute to supporting veterans and their families.
