The Next Loop - Deer Grove East

The Next Loop at Deer Grove East Forest Preserve in Palatine, Illinois is a loop-format trail event organized by EverFurther. The course uses a clearly marked 3.1-mile (5K) loop that runs through mature woodlands, open prairie, and well-maintained natural trails with surfaces of packed dirt, sections of crushed gravel, and smooth singletrack.

The event offers a flexible Endurance Series where runners build mileage one loop at a time and official results reflect completed loops and cumulative loop time. Every loop returns to a centralized start/finish area with a fully stocked aid station and access to personal gear and crew support. The loop schedule includes a recovery period between laps to allow refueling, gear changes, and pacing adjustments.

There are also continuous trail challenge options with a 12-hour time limit and field limits noted for the longer challenges. Athlete services include chip timing with individual lap splits, medical and safety support, and live lap results. Pacers are permitted under event credentialing rules, with one pacer allowed per athlete.

Distances include:

  • 5K
  • 10K
  • 15K
  • Half Marathon (13.1 miles)
  • Marathon (26.2 miles)
  • 50K
  • 40 Mile Challenge
  • 50 Mile Challenge

The format emphasizes consistent support, frequent aid access, and a repeatable loop course that centralizes logistics and allows runners to adjust strategy throughout the day. Visit the organization's website for the most recent information.
