Course & Elevation
The Basel marathon was the 42.195 km distance of the 3-Länderlauf, a road race that starts and finishes on the Marktplatz in Basel and crosses Switzerland, France and Germany. The 3-Länderlauf itself dates from 20 October 1990, but a marathon was added only in May 2024, and the organisers have announced that from 2027 it will be held without a marathon for safety reasons. The marathon was run in May as two laps of the half-marathon course. The route starts in front of the town hall, drops to the old Rhine bridge and crosses the Rhine four times. It follows the east bank to the double-decker Dreirosenbrücke, passes through Saint-Louis and Huningue in France, and crosses the Dreiländerbrücke footbridge to Weil am Rhein in Germany before returning through the Lange Erlen recreation area. The marathon had a time limit of 5 hours 30 minutes. The field was small: in 2026, 93 women finished and the men's winner, Cedric Oesterlé of France, ran 2:29:34. The last marathon was held on 17 May 2026. The half marathon and 10 km, which also cross all three countries, continue, with the next edition on 23 May 2027.
