This course is employed for the Club's long time trials, and it is named after the state park at which it begins.  The boat launch and dock area of Mary Jane Thurstin State Park can be found just inside Henry County just past the western edge of Grand Rapids.  The 25k TT course  follows the Maumee River west before crossing the 109 bridge and returning via Old 24.  The finish is located at the entrance to Providence Metropark.  Riders can then simply cross the river via the Grand Rapids bridge and make their way back to the start at MJT while cooling down.

The venue may be found by taking Old US 24 west to SR 578.  Turn left and cross the Maumee River and then turn right on SR 65.  Continue west on SR 65 through Grand Rapids to Mary Jane Thurstin State Park.  Parking for the time trial is at the marina area of the park, and the entrance for such is located west of the park's main entrance.
