Biel / Bienne Running Days

Bieler Lauftage – Les courses de Bienne is a bilingual city running festival held in Biel/Bienne, Switzerland, taking place from 5 to 6 June 2026. The weekend brings together a spectrum of formats from the flagship 100 km ultramarathon to relays, a half marathon, 10 km events and children’s races, and the site for the Swiss 100 km Championships is hosted within the programme. The event is organised under the Bieler Lauftage brand (c/o Eventra GmbH) and presents an urban, multi-town route that attracts club and individual runners as well as relay teams.

The festival atmosphere includes a Sportexpo and volunteer opportunities, and practical services such as drop bags and bicycle coach support for the 100 km are offered. Finishers of the 100 km receive a T-shirt and a medal, and registration is handled via the official Datasport portal linked from the event pages.
