Cinco De Mayo Run 5K/10K/13.1

The Cinco De Mayo Run 5K/10K/13.1 returns to Piney Creek Hollow Park on May 2, 2026, celebrating both the Mexican holiday and the start of prime running season in Colorado. This multi-distance event offers runners three options: a 5K (3.1 miles), 10K (6.2 miles), and half marathon (13.1 miles), all starting and finishing at the scenic Aurora park.

Located at 6140 S Tower Rd in Aurora, Piney Creek Hollow Park provides a natural setting with rolling terrain and tree-lined paths. The 13:30 start time allows for comfortable morning preparation while avoiding the afternoon heat typical of early May in the Denver metro area. Runners can expect moderate elevation changes and well-marked courses throughout the park's trail system.

Registration typically includes race timing, finisher medals, and post-race refreshments featuring traditional Cinco de Mayo foods. The event attracts both competitive runners seeking spring race goals and recreational participants celebrating the holiday weekend. All three distances follow certified courses with aid stations positioned at key intervals for longer races.
