From big races to Saturday morning group runs—find ultra events and connect with the local endurance sports community.
Looking for an all night running party?
Join us for the Prickly Pine 24-Hour Solo/Relay race in the beautiful Kettle Moraine State Forest! With a variety of time options—6-hour, 12-hour, 24-hour, and a 4-person 24-hour relay—you can choose the challenge that suits you. Not a fan of repeating the same loop? We’ve got you covered with three unique loops: Loop #1 (3 miles), Loop #2 (6 miles), and Loop #3 (9 miles). You decide which loop to tackle each time, and every completed loop counts toward your total mileage!
Jackpot Prizes for the top 5 finishers in the solo event and top team in the relay.
For each 24-hour solo participant and relay team, 25% from your registration fee will be added to the solo and relay Jackpot, respectively.
Solo competitors – 1st place is awarded based on the total miles of completed loops. If you don't finish the loop you're on when time runs out, that loop won't count toward your total. In the event of a tie, the prize money for the tied positions will be combined and evenly split. For example, if two runners tie for first place, the 1st and 2nd place prize amounts are combined and shared. If there’s a 3-way tie, the prizes for 1st, 2nd, and 3rd will be pooled and divided equally.
1st Place = 50% of the Jackpot
2nd Place = 30% of the Jackpot
3rd Place = 10% of the Jackpot
4th Place = 5% of the Jackpot
5th Place = 5% of the Jackpot
Relay Jackpot
The winning team will take home the entire Jackpot! In the event of a tie, each team will select one runner to compete in a final, winner-takes-all lap on the 3-mile loop.
