Arrowhead Endurance Run

Join us for a beautiful timed event at Arrowhead Lake Campground in Johnston City, IL (about 15 minutes north of Marion, IL). The course is a certified 2.07 mile loop around the lake and we offer 3 hour, 6 hour, 12 hour, 12 hour night time, 24 hour and 24 hour relay options!

Arrowhead Lake features a certified 2.07-mile trail that loops around the lake.  The trail is 99% gravel with a small concrete section up the boat ramp.  With less than 50 ft. of elevation change per loop, it offers some fast times and supports big miles as we have had national-level mileage totals in the first two years!  We will have chip timing again by Jason Claunch at Southern Illinois Racing.
