The race distances are precisely measured. The Marathon is 26.2 miles, and the 10 Mile race is 10.0 miles long. The 10 Mile course map is here:  https://www.mapmyrun.com/routes/view/4099620145

The Marathon route starts with two circuits of the 10 Mile, and ends by going straight out & back to the aid station at Will-Cook Rd.

At each turnaround point there is aid, allowing for unprecedented aid coverage during a trail race... miles 3, 5, 8, 10, 13, 15, 18, 20, 23.

Participants all receive a technical trucker hat, and marathon finishers get a finisher's shirt! All finishers receive a unique wooden medal. All participants registered before April 1st receive a personalized bib. You can even pick your lucky number if it's still available!
