Registration Open Now!

Registration for the 10th running of the Door County Half Marathon and Nicolet Bay 5k is now open!

Be part of the celebration on May 6, 2017 in beautiful Peninsula State Park! Run 13.1 miles of beautiful roads closed to traffic, taking you past some of the most beautiful vistas on the peninsula, through quiet woods, and atop the Niagara Escarpment.

Finish at Nicolet Bay Beach, where half marathon participants receive a race shirt and finisher’s medal. Our 5k finishers also get a shirt, and all participants enjoy a post-race party in the park with beer from Door County Brewing Co.!

Both races are capped and WILL fill well before race day.

“Like running in a cathedral in the woods.”

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.”

Jenny Hadfield – Runner’s World

A must-do race! This popular destination race takes full advantage of the natural beauty of Door County, Wis.
