LOWA Ultratrail Fränkische Schweiz 66km: Germany's Limestone Cave-and-Castle Ultra, 48 Minutes from Nuremberg

The officially published D+ is 2,760m — confirmed by an exact match with GPX-derived analysis, making this one of the stronger elevation confidence points in the DTR database. At 41.82m of D+ per kilometre the course ranks 327th most vertically dense out of 390 European trail ultras (Rank 1 = most vertical). The total climbing is spread across many short punchy ascents through limestone rock, caves, and staircase sections (over 1,500 steps confirmed on course) rather than a small number of long sustained climbs.

Harder than the gradient statistics suggest. Average uphill gradient ranks 343rd steepest out of 390 European ultras — near the gentle end of the database — yet the official course description warns of countless steep inclines and technical sections requiring full concentration. The explanation: Fränkische Schweiz delivers short sharp climbs rather than long sustained ramps, over 1,500 staircase steps, cave passages through limestone formations, root-filled singletrack, and river crossings. The downhills are among the gentlest in the database by gradient (rank 72/390) but are technically demanding by surface quality. The race suits experienced trail runners comfortable on technical rocky terrain.

The 2026 (5th anniversary) edition ran on April 25, 2026, and is now closed — it sold out before race day. The 2027 registration timeline has not been announced as of July 2026; check ultratrail-fraenkische-schweiz.de for updates. Entry fee in 2026 was €110 (€1.67 per km) with no additional processing fees noted. The race has sold out in previous editions with medium sell-out intensity; early registration is recommended when the 2027 window opens.

Nuremberg airport (NUE) is approximately 48 minutes from Ebermannstadt, the race start and finish location. Nuremberg has direct rail connections via Forchheim and the Wiesenttalbahn regional line to Ebermannstadt. A last-mile taxi from the station is recommended. Munich airport (MUC) is approximately 2 to 2.75 hours by road or rail. Accommodation in Ebermannstadt is limited; Bamberg (25km away, UNESCO World Heritage City) and Nuremberg are the recommended bases with extensive hotel options at all price points.

Three features stand out. First, the cave sections: runners pass through limestone cave passages and under cliff formations that are genuinely unusual in a race context. Second, the 1,500-step staircase sections: stone staircases built into cliff faces create a stair-climbing challenge that gradient statistics cannot convey. Third, the castle density: Burg Rabenstein, Burg Rabeneck, and Burg Gößweinstein are all visible from the course, giving the 66km a heritage character rare in trail racing. The race finishes at the market square of Ebermannstadt — a festival atmosphere that Trail Magazin (2022) called a race certain to find a place among the top most authentic highland race classics.
