Do you have what it takes? If so, then come join us for an old school race weekend at the 4th annual Sunlight Showdown at Sunlight Mountain Resort. We will start off with a 13 mile mountain bike race on September 23rd and finish with a 13 mile trail run on September 24th. Participate in one of the races or do both on back to back days to see if you have what it takes to complete the full Showdown! We are a race that focuses on fun, fitness and progression rather than podiums and egos(don't worry freaks there are still prizes!)

The Course

Both races will be run on the same 13 mile course with 3000 ft in gain in reverse direction of each other. The race's are run on 75% single track and 25% double track on Sunlight Mountain Resort and the Babbish Gulch trail system during the peak of wildflower season. You will wind through open meadows, pine and aspen forest, stream crossings and will be treated with the best view of Mt Sopris in the valley. Mountain bikers will start off with an 1900 ft climb of Sunlight and the runners will finish with the same decent.

The Bike

I know 13 miles for some of you vets doesn't sound like a lot on a bike, but this is not your millennial buffed out machine built berm on the turn flow course. This is an old school rugged cross country throw your bike on your shoulder kind of race. Fast descents, grinding uphill's and amazing singletrack will have you coming back year after year to test yourself in The Sunlight Showdown.

There will be no aid stations for the mountain bike race

The Run

Challenge yourself with one of the toughest Half Marathons in the state. Whether you are training for a trail marathon or 50k and want to get some speed in or you are new to the distance, this course will not disappoint. Run for speed or run to finish, either way we would love to have you!

There is no cut off time for this race(If you sign up I promise I will be waiting for you at the finish line)

There will be one water only cupless aid station for the run at mile 8.6
