Pere Marquette Endurance Trail Run

The Pere Marquette Endurance Trail Run is a challenging 7.8-mile trail race held annually in December at Pere Marquette State Park in Grafton, Illinois. Celebrating its 35th year, the course features hilly terrain and scenic views through the park. Participants enjoy pre-race coffee and packet pickup in a cozy lodge with a roaring fire, with post-race festivities and awards also hosted there.

The event serves as the RRCA State Championship race, crowning state champions and awarding medals across various age groups and categories. The race proceeds regardless of weather conditions unless the park is officially closed. Visit the organization's website for the most recent information.
