Baby Backyard 5K - 50K ULTRA

The Baby Backyard 5K - 50K ULTRA is a trail backyard-ultra event held in Maple Grove, MN, at 12420 James Deane Parkway. The format uses repeating 5K segments: a new 5K starts each hour and participants may continue until they reach 50K. Runners and walkers can join for any number of laps; each completed 5K counts as an official finish in this no DNF event.

Event management provides course support and aid for the duration, including a primary start/finish cover with water, race swag, and snacks. A virtual option is available; virtual participants can run their own 5K course and receive race-day swag by mail. Kids may run, ride, walk, or hike for free, and crew, family, and spectators are welcome.

This event is part of the RRCA Championship Series 50K; medals will be awarded to age-group individuals who complete the 50K the fastest. Gatorade Endurance is listed as a hydration sponsor for the 50K. The race is also included in the Upper Midwest Trail Runners Too Fun Trail Run Series, and UMTR members earn series points.

All registration fees are donated to the Children's MN Cancer Fund. Registration closes July 31. Visit the organization's website for the most recent information.
