Calling all cold-blooded runners, rebels, and fitness junkies!
The ColderBOLDER 5K on December 1, 2018, is open to everyone. So layer up, grab a hat, and join us. Oh yes you can!
Race, Run, Jog, or Walk
We want you to have the time of your life no matter how fast you are, even while freezing your buns off!
Wind through the scenic University of Colorado campus, the course finishes inside the toasty Balch Field House.
After you finish, check out the expo for great food and drink samples, and tons of other schwag.
Finish Line Party
The perfect way to end your 5K is running into the Balch Field House to celebrate with friends and family. Watch the Cold Medal Ceremony while you enjoy your free goodies.
This 5K is a little different, but so are those of us who enjoy running in the cold. It is actually 13 individual races. The top three men and women in each race win Cold Medals. That’s 78 medalists total.
The First 12 Races
These are for people who participated in the last BolderBOULDER. Each individual race puts people together who are about the same speed. Why? So everyone has a shot at winning. For example, if you finished the BolderBOULDER in 52 minutes you would race against people who finished between 52-54 minutes. It’s your chance at personal glory and eternal fame. You got this.
The 13th and Final Race
This is open to everyone, runners, joggers and walkers. We all want to stay fit over the holidays, and we want everyone to be able to participate. So, break out in a cold sweat with us. Let’s pour cold water on those winter blues.
We’ve Got Your Back
We know how you like to be treated.
