The Polumaraton Ivan Starek is a road running event staged every year in November at Lake Jarun in Zagreb, capital of Croatia.

Created for the Summer Universiade 1987, Jarun is home to a rowing regatta course, sports facilities, shingle beaches, cafés and bars.

Starting and finishing at the western end of the lake, the event comprises three races:

  • 5km Jarunska petica
  • 10km Jarunska desetka
  • 21.1km Polumaraton (half marathon)

Following the road that encircles Lake Jarun, the half marathon is three laps around the lake. The first lap includes a detour to the Otok Hrvatske mladeži (Island of the Croatian Youth).

The course has been accurately measured and it is completely flat and closed to traffic for the time of the race, so it offers a fine opportunity to set a personal best time.
