IMPORTANT: Course maps are published for informational purposes only, for registered racers only. Cook County Forest Preserve rules prohibit speed training outside of the scheduled race day. All trails at Palos are two-way and open to multiple user groups including cyclists, runners, hikers, and equestrians. EXPECT THE TRAILS TO BE BUSY DURING THE RUN-UP TO THE RACE, INCLUDING TRAIL WORKERS WITH EQUIPMENT AND MACHINERY ON THE TRAIL. NON-RACE TRAFFIC SHOULD AVOID THE TRAILS ON RACE DAY FOR THE SAFETY OF ALL.
