Course and logistics
The course is nearly flat with a short 10-foot rise on the loop and uses hard crushed rock, soft hiking trails under tree canopy, and smooth horse trails. Under dry conditions most runners wear road shoes; some sections can become muddy when wet. The loop is supported by four staffed aid stations on course: Elm Lake (start/finish), Sawmill, Hale Lake, and 40 Acre Lake, plus an unmanned water point at the Nature Center for shorter events. All runners must carry a personal hydration device - no cups are provided at aid stations. Drop bags for Sawmill are handled from the Elm Lake area. Pacers are allowed for the 100M (final two loops) and for the 100K (final loop only); pacers are not allowed in marathon or half marathon events. Special event park passes are required for all individuals 13 years and older; state park camping must be reserved through the official reservation system.
