Catskill 100 - The Running Kind

The Catskill 100 is an approximately 100 mile trail race in the Catskill Mountains that crosses four distinct New York State Wilderness Areas. The route includes the entirety of the Devil’s Path and summits 12 of the 33 Catskill High Peaks, including Indian Head, Twin, Sugarloaf, Plateau, Hunter, West Kill, Wittenberg, Cornell, Slide, Big Indian, Eagle and Balsam. The course features technical terrain and more than 25,000 ft of elevation gain and descent, and is intended for experienced mountain runners.

Entries require an application and qualifying experience. Runners who have completed a 100 mile or 100 km race within the last two years gain entry; a list of pre‑approved qualifier races is available for reference. Due to permitting and wilderness preservation, runners will start in heats of 15 every five minutes; female and non‑binary runners are released before men and the race is limiting spots to balance participation.

Crew and pacer policies are specified. Crew access is permitted at Aid 2, Aid 3, Aid 4, Aid 7, Aid 8 and Aid 9; one car per crew. Pacers must register, wear a pacer bib, check in at aid stations, carry the same required gear as runners, and only one pacer may be on course with a runner at a time.

Drop bags are available at Aid 2, Aid 4, Aid 6 and Aid 8 and should be labeled and rainproof. This event is organized as a zero carbon event with a registration fee to offset emissions and partnerships for carbon projects and local donations.
