Innsbruck Alpine Trailrun Festival K85 2027: Midnight City Start and 3,880m D+

Among 390 European ultras tracked by DiscoverTrailRaces, the K85 ranks 107th for biggest single-ascent magnitude — a 509m top climb in the top 27.4% for single-climb scale — and 156th for single-descent drama, dropping 1,033m at -11.15% average gradient. D+/km ranks 239th at 44.7m/km, near the database midpoint for vertical density. Average uphill gradient ranks 240th steepest (below median) and average descent gradient ranks 178th on the inverted gentleness scale (slightly gentler than average). Official D+ is 3,880m over 86.8km, confirmed by both race website and GPX analysis. The race targets experienced ultra runners in the 80–100km range; trails alternate between flowing and technically demanding terrain across the Nordkette mountain range above Innsbruck.

Yes — the K85 is certified as a UTMB Index 100K race, meaning finishers earn UTMB Index points. It also carries ITRA 4 points per finish. The race is NOT a UTMB World Series event and does not award UTMB Running Stones. Runners building World Series qualifying stone counts should note the distinction: UTMB Index points contribute to the broader index pool but are separate from the World Series pathway. The K85 shares the midnight Landestheater start with the K110 Masters of Innsbruck, which is also a UTMB Index 100K race. Verify current UTMB Index and ITRA qualification details with both organisations before making entry decisions, as rules can change between seasons.
