About the Event

This will be the 36th year of the Pere Marquette Endurance Trail Run. 7.8 miles of hills and incredible scenery through the park in December. Packet pickup and pre-race coffee available in the beautiful lodge with a roaring fire. Post race festivities and awards are also in the lodge.

The race is a go regardless of rain, sleet, snow, ice, mud or muck. It's a trail race not a day at the beach. HOWEVER.... should the Park Service close Pere Marquette State Park due to severe inclement weather or other unforeseen cause, Metro Tri Club will cancel the event and offer no refunds or deferments.

Packet Pickup: Race day starting at 7:30AM in the Pere Marquette State Park Lodge

Race Awards: Male and Female Overall, Male and Female Masters (40+), Top 3 age group in 5-year increments from 16 to the oldest person to finish
