No Meltdowns



The 2022 ColderBOLDER 5K will take place on Saturday, December 10th.

The ColderBOLDER is 14 individual races – 13 invitational races and one open race. The top three men and women in each race win Medals. That’s 84 medalists total. So come break out in a cold sweat with us. Pour cold water on those winter blues. The first 13 races are for people who participated in the 2022 BOLDERBoulder. Each race puts people together who are about the same speed. Why? So that anyone has a shot at winning. For example, if you finished, the BOLDERBoulder in 52 minutes you race against people who finished between 52-53:59 minutes. It’s everyone’s chance at personal glory and eternal fame.
