Mile Madness Endurance Run

Mile Madness Endurance Run

Mile Madness is a multi-day ultrarunning event held September 18-21, 2026, at a regional park in Auburn, California. The format uses a short looped course with continuous laps, a central aid station, and an additional aid station near the half-mile point. Aid stations provide meals, typical aid station food and electrolytes, music, lighting, and on-site volunteers. Food trucks, restrooms, and on-site massage services are listed among available amenities.

The event program includes multiple timed and distance options, with individual and team relay entries. Special milestone buckles are awarded for finishing 100 miles, 150 miles, and 200 miles. Podium awards are determined by most laps completed in timed events; the 100-mile race awards podium places by fastest finishing times. A bib raffle will be held during the event, and registered entrants receive event SWAG such as a race shirt or jacket (size availability may be limited after September 1, 2026).

Relay teams may consist of four to ten runners; team members register individually, share a single team bib while on course, and may use pacer bibs for support. The event offers a rollover policy for entries up to 24 hours before race start. Family-oriented amenities include a staffed cheer zone with shade, games, and a poster-making station.
