Mingus Mayhem

Mingus Mayhem is an endurance running event in Coos Bay, OR, organized by Run Pacifica. The event offers a long-duration loop plus a shorter option: a 9-hour event and a 2-hour option.

The course uses a 1.12 mile lap with about 140 feet of elevation gain per lap. Surfaces are roughly 70% unpaved and 30% paved, with the unpaved sections consisting of double-track trail and gravel road that see very light vehicle use from park visitors. The course is described as runnable in road shoes.

Support at the venue includes a large shared water jug and a park gazebo used as a base camp with picnic benches or tables for weather coverage. Participants are expected to carry their own fuel and any other ultramarathon supplies they need. The 2-hour option is arranged so participants can finish together and visit 7 Devils Brewery afterward; alternate 2-hour start slots may be available.

The event location is listed as Mingus Park in Coos Bay, with a mapped address at 725 N 10th St. The event is free to enter. Visit the organization's website for the most recent information.
