Sloth Run 5K/10K/13.1 - Denver/Aurora
Sloth Run is a community-focused running event at Piney Creek Hollow Park in Centennial, Colorado on April 10, 2027. The event offers multiple distance options and a virtual alternative, and fields are capped per wave to keep participation small and local. When a wave fills, registration for that wave closes; a waitlist and a virtual option are available.
Distances offered:
- 5K
- 10K
- Half marathon (13.1)
- Virtual run
- Family 1 mile fun run
Timing is optional. Participants may track their own time with devices or apps such as Strava, RunKeeper, or Nike Run and submit results via the event’s online form for posting. No timing chips are used. Race bibs are handed out on race day and event coordinators remain on site for three hours after the first wave.
Swag and extras are included for participants. Items listed for registrants include a running T-shirt shipped to U.S. addresses, a finisher medal, a virtual training run emailed before the event, online results and a certificate of completion, and an invitation to join a local running club. A lightweight technical shirt upgrade is available for an additional five dollars. Swag shirts are shipped and typically arrive the week of the race.
