The 3Laenderlauf – Basel > St.Louis > Weil am Rhein is an annual cross-border road race with start and finish on Basel's Marktplatz in front of the Rathaus. The 2026 edition (34th Dreiländerlauf) is scheduled for 17 May 2026 and features three officially measured distances: Marathon, Halbmarathon and a 10 km run. Runners traverse Switzerland, France and Germany on a scenic course that includes multiple Rhine crossings and several notable city landmarks. The event is organised by Verein 3Länderlauf in cooperation with regional partners and publishes official results and start lists via Datasport.
For entrants the race offers a finisher T-shirt and finisher medal as part of the entry package, and tiered CHF entry fees were applied in 2026 according to the published pricing windows. The organiser's registration pages for the 2026 edition state that entries are sold out and that no waiting list is offered for that year. Competitors and spectators can find practical information, route maps and official communications on the event website and the organiser's social channels.
