The Maraton treh src, or Three Hearts Marathon, is by far the biggest running event in the eastern part of Slovenia.

Held annually in May, it's an event for the whole family:

  • 42.2km maraton (marathon)
  • 21.1km polmaraton (half marathon)
  • 10km tek (10k run)
  • 8.7km nordijska hoja (nordic walking)
  • 5km tek (5k run)
  • 250m, 600m, 1km Veveričkin in srčkov tek (kids' races)
  • 10km pohod (10k hike)

The start and the finish are at the huge Hotel Radin in the Zdravilišče Radenci (Radenci Spa Resort) in the small town of Radenci.

The shorter races take place on Slovenian soil whereas the half and the full marathon cross the border into Austria for a visit of Bad Radkersburg, another spa town offering, like Radenci, relaxation in thermal pools.

From Bad Radkersburg, half marathon runners run back home to Radenci.

Marathoners run a long loop through fields and villages, both in Austria and Slovenia, crossing the state border four times, before they head for the finish line.

Both races are gently undulating with a difference of about 35 metres between the lowest and the highest point on the course.

The time limit to complete the 42.2km marathon is six hours.
