Location

William O'Brien State Park
16821 O Brien Trail North
Marine on Saint Croix, Minnesota.
William O'Brien State is just off state highway MN-95, north of Marine on Saint Croix
Races start at the William O'Brien State Park Visitor Center, just inside the park and to the left.
Parking is at the Visitor Center lot. Please be considerate of other Center users.

Due to major construction at the park near the river in 2023 and 2024, new courses are in the works. I hope to have this confirmed by April 1st. Once this is done, an email to past runners and a post to Facebook will be sent telling that registration is open. Check back later for further information.
