What is the terrain and course character like?

The course is highly technical, consisting of approximately 80% single-track dirt trails with some fire roads. Runners can expect a demanding environment featuring rocks, roots, ruts, and creek crossings. The terrain is described as rolling to hilly, with total elevation gain ranging from roughly 2,500 ft to 7,500 ft depending on the distance chosen. Because of the technical nature of the footing, constant focus is required to navigate the course safely.

What weather and environmental conditions should I expect?

Participants should prepare for high heat and humidity levels typical of Illinois in late August. The environment is a dense forest consisting of oak-hickory, maple-beech, and pine. Runners should also be aware of potential wildlife encounters, including snakes, hornets, and bees, particularly during night running for the longer distances.

What race strategy is recommended for this course?

Due to the specific layout and conditions, the following insights are provided:

• →Prioritize technicality over speed: The rocky and rooted terrain will naturally slow the pace more than elevation alone.
• →Utilize the loop format: The figure-eight design allows runners to revisit familiar terrain, which can assist with mental pacing.
• →Manage heat strictly: Maintaining hydration and electrolyte balance is critical due to the humidity.
• →Maintain footing discipline: The course requires constant attention to avoid trips or falls on technical sections.
