About the Event

Founded in 1979, the Eldorado Run for the Cure is the longest operating charitable footrace in the State of Colorado. All proceeds from the annual four-mile run benefit the Colorado Cancer Foundation's life saving work, from funding oncology research at the University of Colorado's (CU) Division of Medical Oncology to aiding patients at the CU Hospital in Aurora, CO.

Each year, the run has developed and grown, and in 2023 a new course was introduced, routing participants along the scenic South Boulder Creek, which winds through the high cliff walls of historic Eldorado Canyon.
