The Lowdown
20 van Alphen is the opening road race of the Dutch running season, held in Alphen aan den Rijn on the first weekend of March. The 2027 edition is the 60th. The event began as a 20 km race, and the headline distance today is the half marathon, which starts at noon on Sunday. Every distance starts on the Prins Bernardlaan and runs over fully paved roads through town to a finish in the Burgemeester Visserpark. The half marathon is two different laps of about 10 km each, and the Atletiekunie has measured and certified the half marathon and 10 km courses. The 2026 edition drew about 9,600 runners across all distances, and the half marathon sold out in early January that year. The 10 km, 5 km, 2.5 km and 1K Family Run share the weekend, along with a Saturday FunRun and the Alphen City Walk. Registration opens on 1 December 2026 through Atleta, with early-registration discounts in December and January.
