Organiser's Description
SECOND WIND RUNNING CLUB WELCOMES YOU TO THE ALLERTON PARK TRAIL RUN!
Let's hit the trails! A good portion of the 5.7-mile course follows the Sangamon River which has proven quite challenging over the years. Runners may find hidden roots, ruts, sharp turns, and other obstacles. We donate a portion of the proceeds back to Allerton Park for trail maintenance or park enhancements. Our donations have been used towards a railing at a dangerous spot, trail erosion control, recycle bins, water fountain bottle filling station, a new caf'e in the visitor's center, and more. We feel quite fortunate that the park allows us to bring so many into it and pound the trails!
