Welcome to the 15th edition of the DPR Trail Half-Marathon, Marathon, 50 Km and 50 Mile Ultra Marathon along the beautiful and fast Des Plaines River Trail in Lake County, Illinois starting and finishing at Half Day Forest Preserve. With expected cool temperatures, flat terrain, and ideal running surface, you'll find this trail to be extremely fast, which is perfect for a personal best, or a Boston Qualifying time. (Marathon is a Boston Qualifier!)

This race is a CUPLESS EVENT (bring your own cup, hydration pack, water bottle, etc).

Course Description: The DPR Trail is 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. 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. If the course is flooded we will run the ALTERNATE course.

Awards: Finisher’s medal for every distance. Awards for overall male and female winners for each race and for 1st Place AG winners in each age group.

T-Shirts: Available for participants who register on or before August 15th.

Waitlist: Available if races reach capacity. Registration is not charged until accepted. Waitlist registration closes at different times before the event.
