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.”
