Ski Mountaineering — FKT Records

Haute Route
Chamonix — Zermatt

The Haute Route Chamonix–Zermatt is one of the most iconic ski mountaineering routes in the Alps: 100.5 km through the Valais Alps, linking the Mont Blanc massif to the Matterhorn via glaciers, passes above 3,500 m and deep valleys. Around 8,200 m of elevation gain across 18 segments — an exceptional terrain for fastest known time (FKT) attempts.

Haute Route Ski Mountaineering Records

Men (duo)

Mathéo Jacquemoud & William Boffelli 13h 27m
5 avril 2026

Two world-class ski mountaineers. Jacquemoud, former world champion, is renowned for his consistency and racing intelligence. Boffelli, ultra-enduring and highly technical, excels on long traverses. Their record is exceptional for its consistency: minimal pauses, ultra-fast transitions and perfect effort management. This is the absolute reference on the Haute Route.

Samuel Équy & Benjamin Védrines 14h 54m
10 avril 2023

An atypical duo blending ski mountaineering and high-level alpinism. Védrines is known for fast mountain enchainments (Eiger, Matterhorn, etc.), while Équy is a specialist in long endurance efforts. Their record marked a strategic breakthrough: high pace from the start and a more "alpinist" than purely competitive approach.

Bastien Fleury & Olivier Meynet 16h 35m
21 mars 2016

Two strong Swiss athletes from the classic ski mountaineering circuit. Their record held for a long time thanks to prudent but effective management. At the time, equipment and route knowledge were less optimized than today.

Stéphane Brosse & Lionel Bonnel 21h 11m
2008

Pioneers of speed on the modern Haute Route. Stéphane Brosse, a ski mountaineering legend, profoundly shaped the discipline before his passing in 2012. Their performance opened the way for modern record attempts.

Women (duo)

Hillary Gerardi & Valentine Fabre 22h 35m
7 avril 2026

An extremely complementary duo: Gerardi, a world-class ultra-trail runner (Mont Blanc record), brings exceptional endurance, while Fabre is a ski mountaineering and technical traverse specialist. Their record shows spectacular progression in women's performance, with a strategy now very close to men's standards.

Clara Masserey & Gaëlle Perrier 23h 35m
4 avril 2025

A solid, well-matched duo, highly experienced in ski mountaineering. Their record had already significantly lowered the previous mark thanks to excellent night management and steady progression throughout the course.

Valentine Fabre & Hillary Gerardi 26h 21m
6–7 avril 2021

The first major modern women's reference. This record marked the beginning of professionalized women's attempts on the Haute Route, with specific preparation, reconnaissance and optimized strategy.
