One final ultra of the season can’t hurt that bad, or can it? The Indian Creek Fifties takes advantage of the challenging terrain lying within the South Platte Ranger District of Pike National Forest. Dropping down into the Front Range Valley for a few miles within Roxborough State Park, the Indian Creek Fifties will give you something to think about as you begin to plan the year ahead.

Join us for an unforgettable day on some of Colorado’s least used singletrack trails and a few miles on the Colorado Trail. Through aspen groves and pine stands, this race will challenge you to the core. One last hurrah for the year you just had.
