About the KAT100 100 Miles

KAT100 100 Miles is the headline ultra at KAT100 by UTMB in Austria's Kitzbuhel Alps. The race links Fieberbrunn, steep alpine climbs, and high-trail traverses for a demanding full mountain effort.

Course

The 169K route gains about 9,000 meters through alpine pasture, rocky singletrack, long ridgelines, and sustained climbs around the Kitzbuhel Alps. Expect a technical mountain-ultra profile rather than a runnable road-style course.

Race-day weather

Early August in the Tyrol mountains can bring warm valley starts, cool nights, and fast weather changes above treeline. Carry layers for rain, wind, and nighttime temperature drops.
