The Three Eagle Half Marathon & 5K makes a return for its 11th year! You can expect the same high-quality race and attention to detail as we transition ownership and move forward into the future. Three Eagle Half Marathon & 5K takes place on the pristine Three Eagle Trail, a 13.1-mile crushed limestone trail connecting the towns of Eagle River and Three Lakes, Wisconsin. The gorgeous trail is only enhanced by the beautiful Wisconsin Northwoods and its peak Fall colors. This is a chip-timed, point-to-point race. There will be mile markers at every mile and portable toilets and aid stations available along the route.
