Surly Trail Loppet Half Marathon & 7M

The 13.1-mile race — officially titled the Surly Half Marathon — also features a 7-mile race, which will share the same starting line as the half marathon and the event’s Finn Sisu 5K, with a starting time a half-hour later after the half marathon.
From there, runners make their way along a route that follows roughly a clockwise loop through the park, leading runners down from Wirth Lake toward the Eloise Butler and Erickson trails in the park’s southeastern corner, and then westward toward the Norm Oakvik Trails on the southwestern side of the park, where they’ll make their way along the hilliest section of the course.
Runners then head back in the direction of the lake, near the middle of the park, along the Jar Hill trail, starting a downhill stretch over the next few miles.
The second half of the race brings runners up into the golf course area at the northern end of the park, where the course gets hilly again, especially between mile markers 7 and 9 on the park’s northwestern side.
