If you've ever experienced fall in the Rocky Mountains you know what a magical time it is. With cool temperatures, sunny days, and stunning scenery, many people believe autumn is the best time to get out and enjoy the high country. And while a drive up through the mountains in the fall can be a nice way to spend a day, we think you should take it one step further. We think you should get out and experience it on foot!

The Flaming Foliage Relay takes the best parts of the old Outward Bound Relay route and throws in some new and scenic challenges. This relay begins in the quaint town of Idaho Springs and traverses 165 miles and three rugged mountain passes before finishing in charming Buena Vista on the banks of the Arkansas River. Along the way you'll run on roads and trails through some of the most amazing scenery Colorado has to offer. Join run.Colorado relays for the Flaming Foliage Relay Friday September 11th through Saturday September 12th, 2026.

This life changing relay road race is a team-oriented adventure with experiences and views you'll never forget. Each team consists of either twelve runners and two vehicles (the vast majority of the teams) or six runners and one vehicle (Ultra teams), or any other amount of runners including a solo unsanctioned race.
