1336_0315.jpgThe entire Door County Half Marathon is run on a closed, USATF-certified road course through one of the midwest's most revered destinations - Peninsula State Park. The race begins and ends just a few strides from Nicolet Bay Beach, where the Runners' Concourse is located.

Half marathoners will have access to aid stations nine times throughout the run. Each aid station will have medical personnel and volunteers.  Water and Gatorade will be available at all locations and Cliff Shot Gel will be available at Aid Station E (just before mile marker 8). Please see the course map for details.

Restrooms are located near the Eagle Bluff Lighthouse and near Tennison Bay (Miles 2 and 11 on the half marathon course and Mile 1 on the 5K). All other Aid Stations will have portapotties located just before the aid station.

Door County Half Marathon Course Highlights

  • USATF-certified road course closed to all traffic
  • The course takes runners along the shores of Geen Bay, on the bluffs atop the Niagara Escarpment, and through the secluded woods of Peninsula State Park

  • The course also winds past historical markers and scenic overlooks including the Eagle Bluff Lighthouse, Sven's Bluff, and breathtaking panoramic views of Nicolet Bay, Green Bay and the islands dotting Lake Michigan

  • Eight strategically placed aid stations

  • Experienced medical staff and volunteers

  • Pirates (you'll know what we mean when you finish ;)

Nicolet Bay 5k

The Nicolet Bay 5k will start a few hundred yards from the start of the half marathon and will follow an out-and-back route, rather than a loop. The route will take runners down shore road to the Eagle Bluff Lighthouse, where they will turn around to head back to the Finish Line. 5k runners will use the same finish line as the half marathon runners.
