Zillertal brutality: steep alpine climbs, sky-high panoramas, and a resort town built for race weekends.
Mayrhofen Ultraks Zillertal 50km (RK50) is the shortest of three distances at Austria's Ultraks Zillertal festival in Mayrhofen, Tyrol — a UTMB Index race starting from Josef-Riedl-Platz in the heart of the Zillertal resort town and climbing into the surrounding alpine terrain. With 3,200m D+ over approximately 48km of course, D+/km of 64m ranks 26th of 390 European ultras for vertical density — top 7% most vertical. The race is defined by extreme gradient steepness in both directions: average uphill gradient ranks 22nd of 390 European ultras (top 6% steepest), while average downhill gradient ranks 377th of 390 for gentleness — meaning only 13 races in the database have steeper average descent gradient. The single biggest descent drops 921m at an average gradient of -17.55%. Entry is €115 early bird (€130 from May 1; €140 from race day), plus a platform fee. Not sold out. Nearest airport: Innsbruck (INN), approximately 65 minutes away — not classified as FAR. First held in 2019. 2026 race date: September 4.

D+/km of 64m (based on nominal 50km) ranks 26th of 390 European ultras for vertical density — top 7% most vertical. GPX D- is 3,481m; the format is expected to be a loop or near-loop from Mayrhofen town centre — verify the 2026 route at mayrhofen.ultraks.com/en/rk50/. The race is a UTMB Index event. 2026 race date: September 4, 2026.
Course Profile: Josef-Riedl-Platz to Alpine Zillertal and Back, 3,200m D+ in 50km▼
Q: What is the course route of the Mayrhofen Ultraks Zillertal 50km? A: The RK50 starts from Josef-Riedl-Platz in central Mayrhofen, climbing from the Zillertal valley floor into the surrounding Tyrolean alpine terrain. The Ultraks Zillertal festival co-stages 70km and 101km distances on the same weekend, all based in Mayrhofen. The 101km (Z101) is the race's flagship distance.

Terrain and Gradient: Where the Mayrhofen RK50 Ranks Among 390 European Ultras▼
Q: What is the terrain like on the Mayrhofen Ultraks Zillertal 50km? A: The RK50 is defined by extreme gradient intensity in both ascent and descent. Average uphill gradient ranks 22nd of 390 European ultras (top 6% steepest), while average downhill gradient ranks 377th of 390 for gentleness — placing the RK50 among the 14 most technically demanding descent courses in European ultra running. The single biggest descent drops 921m at -17.55% average gradient. D+/km ranks 26th of 390. Approximately 21% of the course is nominally flat (Mayrhofen valley floor); the remaining 79% runs at extreme gradient in both directions. Technical singletrack, exposed ridgelines, and rocky alpine terrain characterize the mountain sections.
