The race site is located 11 miles north of Hayward, WI at the picturesque Silverthorn Park in Seeley.
The swim takes place in spring-fed Silverthorn Lake. The start will be broken into waves of approximately 30-40 people. It will be an in-water start from the beach with the finish at the same place. It is a counterclockwise course so swimmers will keep buoys on their left. Olympic Course is a two-loop course and the Sprint Course is one loop. The Olympic Course will begin first followed shortly by the Sprint Course athletes. Wave assignments will be posted prior to race day.
The race uses two transition areas to reduce the number of times athletes must cross US Hwy 63. Transition 1 takes place about 50 meters from the beach adjacent to the park pavilion. Transition 2 is located 3/4 mile south of Silverthorn Park in the Vortanz Lumber parking lot.

The majority of the bike course uses the popular Seeley Hills trail system. After leaving the transition area, athletes will ride 0.8 mi south on an ATV trail adjacent to US Hwy 63. At that point riders will make a left turn onto County Rd OO. This is the start of the bike course loop. After 0.8 mi on pavement, riders will make a right turn onto the Seeley Hills trail system. Most of the trails are double-track with one section of single-track included near the end of the loop. Sprint athletes ride one loop. Olympic athletes ride two loops.
Transition 2 takes place at the notable Vortanz Lumber Company, a 1925 sawmill renowned for its Seeley Pine wood. It is located at the intersection of US Hwy 63 and County Road OO approximately 3/4 of mile south of Silverthorn Park.

The run leaves T2 onto County Road OO and immediately turns right into the Uhrenholdt Memorial State Forest. Athletes run on a fun and challenging course with the Sprint completing one loop and the Olympic completing two. The finish is on the railroad bed adjacent to Vortanz Lumber.
