The event begins in downtown Ottawa and follows courses that run along the Illinois River and through Starved Rock State Park.

Packet pickup and an expo take place the day before at Rivers Edge Center. Additional packet pickup occurs on race day at JJR Fitness. For the half-marathon, buses provide transportation to the start from the finish area; there is no return bus service to the park after the race. A gear check is available for participants. A post-race gathering is held at the Lone Buffalo at Tangled Roots Brewing Company in Ottawa.
