Eiger Ultra Trail course maps and aid stations

You race the E250 in a team of two or three and stay within 50 m of each other the whole way. Nothing is marked, so each team needs a GPS device with the official route. The route goes over Sefinafurgga and the Hohtürli, through the Gasterntal and over the Lötschenpass, along the Valais irrigation channels to Belalp, then past the Aletsch and Fiesch glaciers to the Goms, the Grimsel Pass, the Haslital and Rosenlaui.

Kandersteg, Jeizinen, Belalp, Bellwald, Oberwald and Guttannen are Life Bases, where you can sleep, eat and pick up one of your six drop bags. Stechelberg and Finnen are aid stations with no beds. The longest gap is Belalp to Bellwald, 43 km. Stops and distances are from the 2026 supply plan, and the cutoffs from the 2027 regulations.

The E101 starts in the dark at 4 AM and climbs to Grosse Scheidegg. It drops to Bort and climbs back to First, the second time you pass it, then goes by the Bachalpsee and over the Faulhorn. From there it heads past Schynige Platte and down to Burglauenen at the valley floor, where your one drop bag waits. The second half climbs to Wengen and Männlichen and crosses to Kleine Scheidegg. Higher up, at Eigergletscher, it turns onto the traverse beneath the Eiger North Face. The last stretch descends past Brandegg and Pfingstegg to Grindelwald.

Egg has water only, and Eigergletscher is a timed checkpoint with no food or drink. Runners who stop at Burglauenen can run straight to Grindelwald and get an E51 finisher shirt and medal if any are left, with no Running Stones. Stops and distances are the 2026 course; the cutoffs are 2027's.

The organizer warns that the first climb, to Grosse Scheidegg, shouldn't be underestimated. After that you follow the E101 by First and the Bachalpsee to the Faulhorn summit at 2,680 m, then go on toward Schynige Platte before you descend to Burglauenen. From Burglauenen the course runs back up the valley to Grindelwald.

Feld, the Faulhorn and Schwand have food but no crew zone, and Egg is water only. You start at 7:15 or 7:45 AM, by UTMB Index, and the finish closes 13 hours after your block's start. Stops are the 2026 course.

The E35 starts in Burglauenen, a train ride down the valley from Grindelwald. It climbs via Spätenalp to Wengen, then steeply up the Gemsenweg to the Männlichen ridge. With the Eiger, Mönch and Jungfrau ahead, it crosses to Kleine Scheidegg and the moraine below Eigergletscher, turns onto the traverse under the North Face, and descends the Eiger Trail to Trychelegg and Grindelwald.

Crews can meet you at Eigergletscher, but there's no food or drink there. Your bib is a free train ticket from Grindelwald to the start, and there's no parking in Burglauenen. Stops are the 2026 course.

The E16 heads out toward the Wetterhorn. By Wittegg, above Bort at 1,600 m, you're nearly at the course's highest point. The rest runs through forest, small gorges and meadows by Bort, Nodhalten and Holewang, with a fast descent back into Grindelwald.

The route has been waymarked since December 2016, and in a normal year you can train on it for about eight months. Obere Gletscher, Berien and Hohlenwang are drink stations, and Bort has food. Stops are the 2026 course.
