Istrski maraton, Slovenia - a runner in Piran (Copyright © 2019 Hendrik Böttger /


Held on the Istrian peninsula, the Istrski maraton (Istrian Marathon) is one of the most popular running events in Slovenia.

It attracts an international crowd of around 5,000 runners in three races. Almost half of the finishers are women. Usually, all three races sell out well in advance, so early entries are recommended.

In 2022, there will be an entry limit of 2,500 runners.

These race distances are available:

  • 42.2km maraton (marathon)
  • 21.1km polmaraton (half marathon)
  • ca. 10km rekreativni tek (recreational run)

The venue changes from year to year between the coastal towns of Portorož, Izola, Koper and Ankaran:



The marathon route is closed to all traffic and very scenic and varied as it runs along the coast as well as through Istria's beautiful hinterland.

It visits the port of Koper, the picturesque small town of Izola, the historic town of Piran and the beach resort of Portorož.

And it takes the runners along the Parenzana (a disused railway track which has been converted into a cycleway) through olive groves, orchards, vineyards and former railway tunnels.

The course is partly flat and partly hilly.

Competitors run mainly on asphalt roads, cycleways and paved coastal promenades, but there are also a few cobbles and trails.

There is no rich prize fund to attract elite runners. Instead, all efforts go into making it a memorable day for each single participant.
