50 mile, 50k, Marathon and Half Marathon trail race along the beautiful Des Plaines River north of Chicago. The crushed limestone trail is flat and fast.

The DPR Trail is truly awesome and the color changes are OMG-worthy! You'll run through beautiful alternating lush forests and open wetlands on a very flat, wide, crushed gravel trail, free of roots and rocks. 

All of the major road crossings are managed by way of bridges or viaducts (with only 4 minor road crossings along the whole 50K/50 Mile course, 2 on the Marathon course, and none for the Half-Marathon course).

All races are basically an out and back along the northern segment of the Des Plaines River Trail system. This is a TRAIL RACE so you may encounter areas where you may run through some water. This race is run along the Des Plaines River which floods during heavy rains. If the course is flooded we will run the ALTERNATE course.
