Join this beloved 5K run/walk on Sunday, August 16, 2026, at Washington Park in Denver, with the event kicking off at 9am to support cancer research and patient services across Colorado. Registration is available online in advance or day-of at the park, with pricing ranging from $40 (early bird through July 29) to $55 on race day, plus $20 for kids 12 and under. All proceeds benefit Cancer League of Colorado, an all-volunteer nonprofit that directs funds toward cancer research and clinical trials at the University of Colorado Cancer Center and local patient support organizations.
