The Tamarack Health WhistleStop Marathon & Half-Marathon offers runners a truly unforgettable point-to-point experience along the scenic Tri-County Corridor. Set on a limestone gravel rail trail, the surface is mostly firm and fast, though runners should expect a few softer sections typical of rail-trail courses. The course is known for being flat, fast, and runner-friendly, with plenty of well-stocked support stations along the way. Its trail-style footing is far more forgiving on the knees than pavement—making it ideal for first-time marathoners and runners chasing a personal best. Even better, the WhistleStop Marathon is a Boston Marathon qualifier, attracting athletes looking to post fast times on a forgiving surface.
The Tamarack Health WhistleStop Marathon and Half-Marathon is one of the Midwest’s most scenic and beloved races. Since 1998, runners from across the country have come to Ashland, Wisconsin to experience the quiet beauty of northern Wisconsin in peak fall color.
Every October, the Tri-County Corridor Trail becomes the backdrop for this point-to-point race. Starting near Iron River and ending in the heart of Ashland, the course follows a crushed limestone trail lined with trees, historic rail trestles, and glimpses of the Chequamegon Bay. With its gentle downhill slope and soft surface, it is a favorite for runners chasing personal bests or enjoying a more forgiving run through nature.
The full marathon is a USATF-certified course and a Boston Marathon qualifier. For those looking for shorter distances, we also offer a half-marathon, 10K, and 5K so that all levels of runners and walkers can take part in the race weekend.
What truly sets the Tamarack Health WhistleStop apart is the community. Volunteers line the course offering support, residents welcome runners with cheers and cowbells, and the entire weekend is filled with events that bring people together. From the pasta feed to the finish line celebration with live music and food, to the post Blues & Brews, the WhistleStop Marathon is as much about connection as it is about competition.
We invite you to experience the charm of the Northwoods, the warmth of Ashland, and the pride that comes from crossing the finish line at one of Wisconsin’s most iconic running events.
