2026 Door County Half Marathon & Nicolet Bay 5k

The Door County Half Marathon & Nicolet Bay 5K

The Door County Half Marathon begins at 10:00 a.m. and is run on paved surfaces in Peninsula State Park. This U.S. Track and Field certified course starts and finishes near Nicolet Beach. The course winds through the park, giving runners breathtaking views of Lake Michigan, shaded areas through the woods, challenging hills and ever-changing scenery throughout one of Wisconsin’s most popular parks.

The Nicolet Bay 5k begins at 10:15 a.m., just after the start of the half marathon. The race begins a few hundred yards west of the Half Marathon starting line on Shore Road. Participants will follow the out-and-back course to the Eagle Bluff Lighthouse, where runners will turn around to head back on Shore Road to the finish line. The Nicolet Bay 5k will use the same finish line as the half marathon. Nearly all 5k participants will finish before the half marathon runners come through, while providing amazing views of Horseshoe Island, the lake, and the lighthouse.
