Matterhorn Ultraks 2026: Trail Running Beneath Switzerland's Most Iconic Peak

The EXTREME: skyrunning's most demanding public race

The EXTREME was designed by local Zermatt mountain guide and elite skyrunner Martin Anthamatten — who won his own creation in 2024 — and it shows. The 26km course begins with an 1,800m climbing block straight out of the village, then navigates a rocky couloir with fixed ropes, boulder fields, glacial moraine, and a river crossing before reaching the Rothorn-Hutte checkpoint at 3,198m. Above that, runners cross beneath active glacier terrain on polished slabs requiring micro-spikes, ascending to the Platthorn at 3,337m — the race high point and a 360-degree alpine panorama that very few recreational runners ever reach on foot at race pace.

Elite skyrunner Hillary Gerardi described the EXTREME as “part trail running, one part climbing.” William Boffelli, who won in 2025 in 3:25:06, called it “the best race in the world.” For the mass field, most runners take five to eight hours and the experience is predominantly fast hiking on technical terrain rather than running.

Key mandatory equipment: windproof/waterproof jacket, micro-spikes (not optional — glacier terrain), emergency blanket. Entry requires a qualification application with evidence of comparable mountain racing experience.

The SKY and ACTIVE: the accessible distances

The SKY (49km, 3,600m+) is the distance with the most remaining spots as of June 2026, and it is no less spectacular than the EXTREME. The route ascends via Gornergrat (3,089m) — the cog railway viewpoint — and crosses the suspension bridge over the Gorner Gorge before a long descent to Schwarzsee (2,583m) at the 30km checkpoint. The 12.5-hour time limit from the 07:00 start makes it achievable for strong mountain runners with endurance backgrounds. Both the SKY and the EXTREME earn UTMB Index 50K points.

The ACTIVE (19km, 1,150m+) is the recommended entry point for runners new to alpine terrain. It passes through outer Zermatt villages, countryside, above-treeline stretches and the Riffelalp plateau, finishing at Ultraks Plaza in roughly three to six hours. No qualification form required.

For runners building a Skyrunner World Series campaign alongside Ultraks, UTMB 2026 in Chamonix is the companion event for August — the two races sit just one week apart on the Alpine calendar.

The pyramid that defines every step

The Matterhorn (4,478m / 14,692ft) is the 10th highest peak in the Swiss Alps and widely considered the world’s most photographed mountain. Its perfectly pyramidal form — shaped by glacial erosion on a base formed 50-60 million years ago by the Africa-Eurasia tectonic collision — is visible from virtually every point on every Ultraks course. No other Skyrunner World Series race offers the same sustained, close-range view of a single iconic peak from start to finish.

First summited on 14 July 1865 by Edward Whymper’s party via the Hornli ridge, the Matterhorn was the last major unclimbed Alpine peak of the Golden Age of Alpinism. Today around 3,000 summit attempts are made each year, and mountaineers pray at the Schwarzsee chapel (Maria zum Schnee, 2,583m) before heading up — the same Schwarzsee that SKY runners pass at the 30km checkpoint.

For the Riffelsee lake reflection — one of the most photographed Matterhorn viewpoints in the world — take the Gornergrat Bahn to Rotenboden station (on the SKY race route) and walk ten minutes to the water. Best before 09:00 when the surface is still.

Series context: Skyrunner World Series and UTMB Index

The EXTREME’s Skyrunner World Series classification makes Ultraks one of 19 races across 12 countries in the 2026 Merrell Skyrunner World Series (MSWS). As a WHITE race, it awards standard MSWS points (RED races award 1.5x). Athletes need to complete four races plus the season-ending SkyMasters to rank for overall honours, with a prize fund exceeding EUR 250,000.

Alongside the Skyrunner calendar, the EXTREME and SKY races are both listed as UTMB Index 50K events. Finishing either earns points in the UTMB Index system, contributing toward the Running Stones required for CCC and UTMB entry. If you are collecting stones on the Skyrunner circuit, Oman by UTMB 2026 in December offers another 50K Index event at the other end of the season calendar. For runners following the Skyrunner series into the Southern Hemisphere, Patagonia Skyrace 2027 is one to watch for future stone accumulation.

Matterhorn paragliding: the aerial perspective

A tandem paragliding flight above Zermatt delivers the Matterhorn and the Ultraks race terrain from an angle no spectating position on the ground can match. With 218 reviews and a 4.99 rating, the Zermatt tandem flight is one of the most consistently rated experiences in the entire Viator Swiss Alps catalogue. Flights run 20-25 minutes and operate throughout the summer season.

Gornergrat Railway: Europe's highest open-air railway

The Gornergrat Bahn climbs from Zermatt village (1,620m) to the Gornergrat summit (3,089m) in 33 minutes, passing through the terrain the SKY runners will ascend on Saturday morning. Return tickets cost CHF 132 (half price with the Swiss Half Fare Card). At the top, the panorama spans the Gorner Glacier — the second largest in the Alps — the Dufourspitze (Switzerland’s highest point) and 29 other four-thousanders. The Rotenboden stop en route is a ten-minute walk from the Riffelsee lake reflection.

Race weekend tip: take the morning train while the SKY runners are on course and experience the surreal effect of watching competitors climb past the carriage windows at 2,600 metres.

Guided hiking and cycling: exploring the valley on foot or wheel

If you want to experience the terrain directly without a race bib, two guided options stand out. The guided full-day hike (rated 5.0, 8 reviews) takes in the same above-treeline trails that ACTIVE and MOUNTAIN runners will cross, with a local guide navigating route-finding on technical alpine paths. For a faster, lower-intensity option, the private half-day bike tour (rated 5.0, 2 reviews) explores the valley trails and elevated paths accessible from the village without a significant altitude challenge.
