THE DREAM
Held on the Rainbow Trail in the Sangre de Cristo Mountains.
Runners follow a gently rolling trail beneath rugged peaks.
The atmosphere feels more like a festival than a race.
Picture the course in advance
and find the pace that fits you.
Streets lined with cheers, runners all around.
You'll be part of that scene.
Take it slow with the finish still in you,
and meet the city all over again.
From the joy of finishing to the tough moments — read what runners wrote themselves.
“I couldn’t believe how runnable the whole thing was.”The runner took part in their first 50-mile race south of Westcliff. They managed their pace on the Music Pass climb and carried extra water for the long stretch without aid stations, finishing in 10 hours, 57 minutes, and 6 seconds.
