Quick answers
RaceIndex has a GPS course file for Leiden Marathon 10K, so runners can inspect the route line on the map. Elevation charts and ascent figures appear only when that file includes usable elevation data.
The Leiden Marathon 10K route starts at Koninginnelaan, Leiden (new start from 2026, moved from the Breestraat in the city centre for safety reasons) and finishes at Vismarkt, Leiden. The setting includes riverside and city.
Many roads in the city are closed during the event.
