Pain in Moraine

Pain in Moraine - 24-hour 10K loop challenge

Pain in Moraine is a 24-hour loop event at Moraine State Park, South Shore, using the Sunken Garden Trailhead as the base. The course repeats an almost perfect 10K (6.2 miles) loop that uses the Pleasant Valley, Hilltop, and Sunken Garden trails and includes approximately 723 feet of vertical gain per loop.

Participants may arrive at any time during the event to log laps and may leave and return later; intentions should be communicated to the race director. A new timing feature for 2026, Miles of Smiles, will track participants.

There is space near the start/finish for a base camp. Tents and canopies are permitted and must be tethered appropriately. Camp fires and alcohol are not allowed within the state park. The main tent houses a fully stocked aid station and offers hot food including toasted cheese, cheese quesadillas, ramen noodles, hot dogs, and pizza. A mini aid station with water and Gatorade is located at the halfway point.

Event day registration is allowed if capacity permits; cash or Venmo are accepted and swag may be provided with a bib depending on availability. Pre-August 23 registrations receive a pair of 3" wool socks and a Techno Lite Vest. Awards go to the male and female with the most loops; additional awards are given for competitors reaching ultra distances (5+ loops). Runners under 16 must be accompanied by an adult. Crews may assist at the start/finish and at the 3.5 mile water station but must follow parking rules and posted speed limits. A refund or deferment is available for pregnancy or postpartum; contact the race director for details. Visit the organization's website for the most recent information.
