You are the elite runner at the Colder Boulder!

There are 12 invitational races, based on your 10K finish time in the BolderBOULDER which allows you to compete with your peers. For example, runners who ran the BolderBOULDER 10K in 44:00-45:59 are invited to that ColderBOLDER 5K race.

The top three men and women in each race win Cold Medals and an ice-cold YETI Rambler. That’s 78 medalists total.

Invitational

The invite times are not meant to be predicted 5K times. Invited athletes may only run in their invited race, or a faster one if their speed has improved since May.
