Get ready for an epic test of endurance in Kalispell where you'll tackle a 4.167-mile loop every hour until only one runner is left standing! You can compete solo ($100-$125) or join a relay team of 2-4 runners ($50-$70 per person), with the option to register as a non-competitive "Fun Run" team with unlimited participants. The competition caps out at 24 hours, and if multiple teams finish, the fastest one takes the win.
