COLD MEDALS

FOR THE COLD-HEARTED

14 races + 1 Walking wave

The First 13 Invitational Races Are Organized by Pace – Sold Out

If you ran faster than 68:00 at the last BOLDERBoulder you’ll be invited to join these by email. Everyone earns a Finisher’s Medal, but the top 3 male and female finishers in each race earn a special Cold Medal. Everyone has a fair shot to be in the top 3 because you only run with people your speed. For example, if you ran the BOLDERBoulder in 52 minutes your race only includes people who finished between 52:00-53:59 minutes. This is truly your chance at eternal fame and racing glory!

Open Race – Sold Out

The Open Race is for anyone and everyone who wants to run. But it’s most fun to do the COLDERBolder alongside people your pace, so check your last BOLDERBoulder finish time, you may qualify to join one of the 13 invitational races.

Walking Wave – Sold Out

For the first time ever, we added a Walking Wave. This is open for those who want a festive, BRRRisk stroll through CU campus and our winter wonderland. The Walking Wave is not a race (no 1st, 2nd, or 3rd place Cold Medals), but all will receive a Finisher’s Medal!
