100 Bruggenloop

The 100 Bridges Run in Leiden is a unique walking and running event in which participants cross 100 bridges, ranging from centuries-old stone arch bridges to modern bridges in Singelpark. The route follows rivers, canals, tow canals and waterways, passing some of the most beautiful places in the historic city centre, including the Netherlands’ oldest university, Hortus Botanicus and various monuments. The walking event takes place on Saturday 26 September 2026, and the running event on Sunday 27 September 2026.
