COLDERBolder 5K
The sister race to the BOLDERBoulder. It has become increasingly popular, now selling out year after year. The race, run on the first Saturday in December for the past 23 years is the perfect way to start the winter holiday season on the right foot. It finishes in the university’s field house, where festivities and the holiday spirit fill the air.
