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.
