20 van Alphen, live.

The 60th edition of the Dutch season opener

The 20 van Alphen holds its 60th edition on 6 and 7 March 2027 in Alphen aan den Rijn, the race the organiser calls the opening classic of the Dutch running season.

The event is run by Stichting Twintig van Alphen and spreads over a weekend. The main races are on Sunday 7 March, and every distance starts on the Prins Bernardlaan and finishes in the Burgemeester Visserpark, on fully paved roads through Alphen aan den Rijn. Bands and DJs line the route, and timing mats feed the event's own app.

The half marathon starts at 12:00 and is made up of two different laps of about 10 km, to be measured officially by the Atletiekunie. It is open from age 18. The 10 km starts at 14:15 and is open from age 14, while the 5 km starts at 11:15. Earlier in the morning come the 2.5 km at 10:45 and the 1K Family Run at 10:15. Start pens are set by expected finish time, and changing rooms and a bag store are at MBO Rijnland, a short walk from the start.

Saturday 6 March belongs to the Alphen City Walk, with walking routes starting from 09:30, and to an evening programme with a 1 km and a 2.5 km FunRun from 19:00 and a 5 km City Trail at 19:40. Entries open on 1 December 2026.

The paved course suits anyone opening their season with a fast half marathon or 10 km, and the shorter runs suit families. The prize giving takes place in front of the Oude Raadhuis right after the finish, and the park is the place for supporters to gather.

On Livebib you can follow a participant who chooses to share their own live position from the phone they carry. This is not the organiser's timing, so the dot on the map is only as good as that phone and its signal. Official results and split times come from the organiser.
