The 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.

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.

Scott Luchterhand

“I have run several races – and quite honestly this is the one of the best supported run ever. You do an EXCELLENT JOB on all levels. The support is amazing. The volunteers exceptional. I have ZERO complaints or suggestions.”

Sara Frizelle

“I have done a few half marathons around the midwest and this is by far the best. The organization and communication is fantastic and so are the facilities and race perks. The route is also ideal: starting flat, allowing for the body to acclimate ; followed by a steep incline and then down hill once the body gets a little fatigued. I love it!”

Margaret Pennoyer     

“I’ve raced all over the world and The Door County Half Marathon is one of my favorites.  It’s very well organized, it’s in the heart of beautiful and peaceful Door County, and the course rolls through some of the most picturesque half marathon miles in the world.”
