Bieler Lauftage – Les courses de Bienne is an annual multi-distance running festival held in Biel/Bienne, Switzerland, with the 2026 edition scheduled for 5–6 June 2026. The event weekend brings together a broad programme of races centred on the flagship 100 km ultra, plus relays, a half marathon, 10 km night runs, a Coop Kids Run and other community formats. The official event branding appears in German and French, and the organiser’s information and registration are published via the 100km.ch site and the Datasport registration portal. Participants and spectators are drawn to the night-time atmosphere and the variety of distance options offered across the weekend.
The 100 km race is presented as the heart of the Bieler Lauftage and will host the Swiss 100 km Championships in 2026, with a night start and a course that passes through multiple towns before finishing in Biel. The event pages note practical services such as a finisher T-shirt and medal, a secure drop-bag service, refreshment/aid stations and optional bike-coach support for individual 100 km runners. Volunteer opportunities, on-site information points and transport guidance are provided on the official pages, and entrants are directed to the Datasport registration system for fees, insurance and final start procedures. For full schedule details, registration and the athlete guide, consult the official event website and the linked registration/results pages.
