About the race

Centennial, Colorado hosts The Best Races’ Sloth Run at Piney Creek Hollow Park (6140 South Tower Road). The event offers 5K, 10K, and 13.1-mile distances in a relaxed, inclusive vibe focused on fun over competition. It’s branded the Sloth Run—Slow Is the New Fast! with a small, private group format and per-wave caps to keep the atmosphere stress-free.

All paces and ages are welcome, with no timing chips and timing entirely optional via apps; coordinators can help if you wish. Swag includes a shirt mailed to registrants, a finisher medal, towel or giveaway, digital training pack, and online results. Packet pickup is mailed; bibs provided on race day, and a virtual option exists. Visit the organization's website for the most recent information.
