The Race and Rules

Chip timing bibs must be worn on the front and be visible and they cannot be folded.

Bib Information for USATF members: USATF mandates that the Age Group bib MUST be VISIBLE on your back at all times, and chip timing bib on the front. If your Age Group bib is not visibly placed on the back, you may run the risk of being DQ’ed. Please do not cover it with a hydration pack. 

Aid stations will have water, soda, GU Energy gels, Skratch Energy hydration, and other food items such as bananas, fruit, PB&J, chips and other snacks.

If you drop out of the race, please let a race official or aid station captain know.

We are a cup-free race. Runners must carry their own collapsible cup or other drinking device such as water bottles and hydration packs. THERE WILL BE NO DISPOSABLE CUPS AT ANY AID STATION.

Runners do NOT have the right of way at road crossings or on the trail. Be careful at road crossings; pay attention to course monitors and park officials. Be courteous and respectful of hikers, bikers and horses on the trail. Be quiet and cautious going past the horse stable area in Tennessee Valley; we have strict permit use restrictions for that area.

The official course is on the trails and runners will be disqualified for cutting switchbacks.

Poles are not allowed for USATF runners

The finishing time cutoff is 10 hours (5:30 PM). See the Course information for aid station Cutoffs.
