The Next Loop Endurance Series | Deer Grove East

The Next Loop Endurance Series | Deer Grove East
How far can you go... one loop at a time?
Join us at beautiful Deer Grove East Forest Preserve in Palatine, Illinois, for a trail running experience unlike any other. The Next Loop Endurance Series is designed for runners of all abilities—from those attempting their first trail race to experienced ultrarunners looking to test their endurance in a supportive and welcoming environment.
The course features a scenic 5K loop winding through the woodlands, open prairie sections, and well-maintained trails of Deer Grove East. Each loop returns runners to a centralized start/finish area and fully stocked aid station, making pacing, fueling, and recovery simple throughout the day.
The format is straightforward:
A new 5K (3.1-mile) loop begins at the top of every hour.
Complete your loop and use the remaining time to rest, hydrate, eat, and prepare for the next start.
Continue for as many loops as you choose.
Every completed loop counts toward your final distance.
Popular milestones include:
5K
10K
Half Marathon
Marathon
50K
And beyond
This is not an elimination event. There are no penalties for stopping and no minimum distance requirements. Whether you complete one loop or ten, your accomplishment matters.
The Next Loop Endurance Series was created to help runners discover what they are capable of in a low-pressure, highly supportive environment. It's the perfect place to attempt a new distance, learn trail running, train for a future ultra, or simply spend a day on the trails with an encouraging community.
If you are looking for a continuous-running event without the hourly starts, consider registering for The Next 40M/50M Challenge, which is held at the same venue on the same day.
Progression, Not Elimination.
Your Endurance. No Limits. One More Loop.
