Race & Entry Information
The Chilly Cheeks event is held in the traditional duathlon format of Run-Bike-Run. Both runs will be 2.5 miles and the bike course will be 10.8 miles. As always, we will provide a marked and marshaled course, fast & accurate chip timing, light refreshments including Jill's famous banana chocolate chip bread, and some fun mid-winter competition in the heart of Denver.
All athletes who enter before February 1st will get a pair of Chilly Cheeks Sweat Pants included with their entry! These are perfect for pulling on post-race or for lounging around the house. Those who enter on February 1st or later will have the option to purchase a pair while supplies last.
New this year: If snuggly warm Chilly Cheeks sweatpants aren't your thing, you can choose the "No Pants for Me" option and save $10 on your entry fee.
We will be conducting an awards presentation on race day in the following categories:
OPEN CATEGORY: (Any bike is acceptable - no e-bikes): Top-3 male and female finishers in the following divisions: Age 29 & Under, 30-39, 40-49, 50-59, and 60+
