Ajax, a marathon that finishes in an Olympic stadium, and ice as soon as it freezes.
Ajax at the ArenA
The Eredivisie runs August to May in the south-east, twenty minutes by metro. Buy through the club; away fans face restrictions at big games.
Amsterdam Marathon
An October race that starts and finishes inside the 1928 Olympic Stadium and runs out along the Amstel. Flat, fast and free to watch.
Speed skating at Jaap Eden
The outdoor 400-metre oval in Oost opens from autumn to early spring, rents skates and lets anyone on between club sessions.
Rowing at the Bosbaan
The dead-straight course in the Amsterdamse Bos hosts regattas through spring, and the surrounding woods are the city's running and cycling ground.
