Course and logistics
All races start and finish on the Great Lawn at the Calistoga Fairgrounds and use trail access via the Oat Hill Mine Trail and the Palisades Trail. The courses include single track and fire road, one highway crossing at Highway 29, and out-and-back sections. Notable route features include Lasky Point, Table Rock, and the Mount St. Helena Trail.
Net elevation change is listed as about 7,250 feet for the 50k, 5,250 feet for the 35k, and 4,250 feet for the Half Marathon. The 10k is an out-and-back on Oat Hill Mine Trail with a turnaround just past the 2-mile marker.
Aid and support: aid stations are located on the trails and at Highway 29. The 50k has aid station locations around miles 6.5, 10.5, 14, 17, 20.6 and 25. The 35k has stations near miles 6.5, 10.5 and 15. The Half Marathon has stations at mile 1, the Palisades turnaround, and mile 12. The 10k has water at mile 1 and about mile 5.2. Runners are advised to carry up to 40 ounces of water because some trail sections have long gaps between stations.
Cutoffs and drop bags: 50k runners who do not reach the Highway 29 aid station by 11:45 AM are converted to the 35k and become ineligible for awards; a hard cutoff on the 50k return at Highway 29 is also specified. Drop bags may be delivered to the Highway 29 aid area and must be clearly marked. Finishers receive a medal and a t-shirt; awards are given to the top three finishers by gender and age-group awards are offered when fields exceed 50 entrants.
