How far can you go in 12 hours?

The Lake Haigler 12-Hour endurance challenge invites runners to see how far they can go in 12 hours on a rolling, singletrack 5K loop that winds around and near beautiful Lake Haigler.

Whether you’re chasing a personal best or simply looking to spend a day on the trails, this event delivers a laid-back, community-driven ultrarunning experience. A fully stocked aid station at the start/finish keeps you fueled every lap, so you can focus on finding your rhythm and pushing your limits.

With limited capacity, early registration is strongly encouraged.
