Course Description - 5K, 10K, 1/2 Marathon 
The start is a traditional cross country start with the entire field toeing the line.  At the gun, runners cross a 200M open field before heading out on the trail system.  Over 90% of the race is through Nashotah Park's forests and past both Forest Lake and Grass Lake.  The trails are wide and are groomed year round.  At the finish, runners leave the trail for the last 100M open field sprint to the finish line.  The 5K is one loop and the 10K is two loops. The half marathon is two laps on the outer course and one lap on the 5K course. Course maps can be downloaded by clicking on the link at the bottom of the page.
