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.


A nice dry bike route

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.

Point Standings - Categories - Awards

Points will be awarded to the top-15 male and female finishers in each category in both the duathlon and the run at each race. Points will accumulate at all three events, however you must earn points in the same category in at least 2 series events in order to be eligible for a series award. Points are not transferrable between the duathlon and the run, and they are not transferrable between categories in the duathlon such as 30-39 open division and 44 & Under Fat Tire.

DUATHLON DIVISIONS:
Open 29 & under
Open 30-39
Open 40-49
Open 50-59
Open 60+
Fat Tire 44 & Under
Fat Tire 45+

OPEN vs FAT TIRE: If you enter the Fat Tire Division, you must ride a mountain bike or Hybrid with a minimum tire width of 1.90. If you enter the Open Division, you may ride whatever type of bike the weather and course conditions dictate. Please DO NOT switch from the open division to fat tire if we get snowy conditions at a race. Series points will not transfer between categories. Open allows you to ride a road bike if it is dry, or a mountain bike if it is snowy. If there is a chance you might choose to ride your road bike at any of the races, please choose OPEN.

RUN DIVISIONS:
29 & under
30-39
40-49
50-59
60+

Race results and your series age will be based on your age on December 31, 2019 to avoid the situation where a person starts the series in one category and moves into a different category in the January or February event.

Remember, 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 with the course condition to assist you in choosing your bike and shoes for the event. No pre-race email will be sent. You can find a link to the course updates in the registration section.

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.

There will be no awards presented for the three events individually. Instead, points will be awarded to the top-15 male and female finishers in each category as follows:

PLACE        POINTS
1              20
