Denver’s low key, low cost multisport winter series!!!

The Chilly Cheeks Winter Series is composed of three fun run-bike events at the Cherry Creek Reservoir. We provide a marked and marshaled course, fast & accurate chip timing, light refreshments, and some fun mid-winter competition in the heart of Denver.

The Duathlon Series

The Chilly Cheeks Duathlon Series is composed of 3 events – each with a different format. Each race is comprised of approximately 4 miles of running on paved roads, bike paths, and dirt trails. There will also be approximately 10 miles of cycling in each race. The entire bike course is held on paved park roadways.

December Format: 4 mile run followed by a 10 mile bike ride
January Format: 1.25 mile run, 10 mile bike, 2.75 mile run
February Format: 10 mile bike ride followed by a 4 mile run

Keep in mind, this is a winter event, and although the entire bike course is paved, there may be snow, sand, and/or ice along the route. This website will be updated approximately 2 days before each event (no emails will be sent) with the course conditions to assist you in choosing your bike and shoes for the event. The photos on this page will give you an idea of the variety of conditions you may experience in this series.

Races will be contested regardless of conditions – and if the weather warrants we may change the distances, course, or format of the race accordingly, so no grumbling – this is all about having fun in the winter.

4 Mile Run Series

The Chilly Cheeks Run Series events follow the same fun run course as the duathlon, covering a mix of road, paved bike path, and well maintained dirt trails.

The December and January runs will begin promptly at 10:00am. The Run-Only wave of the February race will begin at 10:20am. Packet pick-up on all three dates will close at 10:00am.

This is a no-frills event – we don’t do awards or shirts, but we do have some yummy goodies afterwards and this is a very supportive and fun group of athletes. All races will be chip-timed.

Races will be contested regardless of conditions – and if the weather warrants we may change the distance or course, so no grumbling – this is all about having fun in the winter. Be prepared for dry roads and trails, but also be prepared for knee-deep snow! This website will be updated approximately 2 days before each event with the course condition to assist you in choosing your shoes and clothing for the event. No pre-race email updates will be sent.
