Run for Breast Cancer 5K/10K/13.1

The Run for Breast Cancer 5K/10K/13.1 returns to Piney Creek Hollow Park on April 4, 2026, offering runners three distance options through Aurora's scenic trail system. The event supports breast cancer awareness and research funding, drawing participants from across the Denver metro area to this community-focused race.

Piney Creek Hollow Park's rolling terrain and paved pathways provide an accessible course for runners of all abilities. The 5K route circles the park's main loop; the 10K extends into surrounding neighborhoods; the half marathon incorporates additional trail segments through Cherry Creek State Park connections.

Registration typically includes race packet pickup, timing chip, commemorative t-shirt, and post-race refreshments. Awards ceremonies recognize overall winners and age group champions across all three distances. Proceeds benefit local breast cancer support organizations and research initiatives throughout Colorado.
