Our Commitment

Organizing, presenting and managing the ColderBOLDER is part art and part science. It takes 364 days of dreaming, brainstorming, planning and sweat to stage the best winter road race on the planet. Our passion and commitment is to deliver an amazing experience for all participates, spectators and volunteers. And we aspire to make the experience better, year after year.

From the founding moment of the ColderBOLDER, we have continually striven to find new ways to make this event the best experience for you. Exciting on course entertainment, the invention of the wave starts, the first RFID timing at every mile in a mass participation event, and no hidden service charges.

In 2014 we announced another first, the ColderBOLDER GuaRUNtee. If you can’t run the ColderBOLDER you signed up for, we can roll your registration over to the next year’s event for only $20. And, you won’t need an excuse from your mom or a note from your doc. It’s our way of raising the bar on your experience, again.

And this year, we diverted enough waste to consider the ColderBOLDER a zero waste event. Thanks to everyone who helped make this year a sustainaCOLD 5K!


Committed to the Sport of Running

Our professional race at BolderBOULDER is the largest international road-racing team competition held each year in the United States. We promote and make donations to the University of Colorado’s cross country and track and field programs.


Committed to Honoring Those Who Serve

Our Memorial Day Tribute is the nation’s largest Memorial Day celebration. We offer discounts to active military members, and our satellite races allow over 2,000 military personnel to run their own BolderBOULDER at dozens of U.S. bases and posts around the world; even aboard US Navy ships.

Committed to Our Local Community

BolderBOULDER donates funds to dozens of non-profit groups who help us as volunteers on race day. Our BBRacers Club helps local elementary and middle school students, teachers and families participate in the BolderBOULDER.
