Saturday features five tough but beautiful miles along the Crooked Lake path! As hilly as any section of Sunday's half or full marathon, this is a kick butt trail course that is sure to please ... and beat you to a pulp!

Sunday's half and full marathon course is a 13.1-mile single-track loop through Lower Michigan wilderness. Runners will experience constant hills and exquisite beauty including views of 10 lakes. It's a wide, well used trail with opportunity to pass. Aid comes about every 3 miles, water and Ultima. There will be 2 GU stops in the half and 4 in the Marathon ... loop 2!
