Run for Breast Cancer 5K/10K/13.1 DENVER/AURORA

This event takes place at Piney Creek Hollow Park, 6140 South Tower Road, Centennial, CO 80016. Multiple distances are offered and the event includes both in-person and virtual participation options.

  • 5K
  • 10K

The event supports breast cancer awareness and fundraising; fundraising is optional and the organizer reports ongoing charity initiatives. The in-person format is organized as smaller, capped waves with coordinators on site. Late participants may start on arrival and coordinators remain for three hours after the first wave. Timing is optional: participants may track time with running apps and submit results for posting, and the event does not use timing chips.

Race material and finish items are provided. Race bibs are given on race day and most swag is shipped to the registrant's US mailing address; the package typically includes a running T-shirt, a finisher's towel or giveaway, a finisher's medal, and a digital training pack. A technical running shirt is available as an optional upgrade for an additional fee. Virtual participants can complete the run at any location and submit results to receive a medal.

Final race details and course maps are distributed to participants in advance. Visit the organization's website for the most recent information.
