Winter Running Tradition

Baby, it's cold outside...
And we're gonna take it on, because that's what living in Colorado is all about.
Let's conquer the elements together at this WINTERY January 5k/10k race.
We're staying cool in Colorado, one mile at a time!
Starting at Louisville's Coal Creek Golf Course and running through neighborhoods, past fairways and along ponds and open spaces, the wintery 5k/10k sometimes has sun and 65* without a cloud in the sky and sometimes, we're up against negative temps and blowing snow. What will this year bring? Are you up for the challenge?

SWAG INCLUDES:
+ Warm Winter Knit Beanie
+ Knit Running Gloves
+ Hot Finish Line Beverage & Snacks
+ Chip Timing
