Course & Elevation
The Mizuno Half Marathon is the half marathon of the TCS Amsterdam Marathon weekend, run on the Sunday in October after the full marathon has started. The organisers call it the largest half marathon in the Netherlands, and the entry limit for 2026 was 15,000 runners. The race starts on Stadionweg near the Olympic Stadium, in start waves that in 2026 ran from 13:20 to about 14:00, and finishes inside the Olympic Stadium, built for the 1928 Games. According to the organisers' route description, runners go from Stadionweg along Churchilllaan and Rijnstraat and cross the Amstel on the Utrechtsebrug, then continue through the Watergraafsmeer and Zeeburg; otherwise the course is the same as the marathon route, which passes the Rijksmuseum, the Amstel and the Vondelpark. The time limit is 3 hours. The marathon, the 7.5K and the kids and Heroes runs are held on the same weekend; the 2027 weekend is on 30 and 31 October, and registration for it opens on 19 December.
