About This Race
The 173K represents the ultimate test at KAT100, demanding exceptional endurance and pacing discipline across the full spectrum of Kitzbühel Alps terrain over what becomes a multi-day mental and physical challenge. This distance requires runners to demonstrate mastery of technical alpine descents, sustained climbing ability, and the psychological resilience needed for extended time on challenging mountain terrain, often finishing well into the following day. Best suited for experienced ultra-distance runners seeking a serious stepping stone toward 200K events, the 173K tests every aspect of mountain ultra running while remaining more accessible than the full 200K distance.
