The Maraton treh src, or Three Hearts Marathon, is the biggest running event in the eastern part of Slovenia.
Held annually in May, it attracts several thousand runners to the small mineral-water-producing spa town of Radenci which sits on the right bank of the Mura river near the border with Austria.
The event features races for all ages and levels of runners:
- 300m, 600m, 1km tek (kids' races)
- 5.3km tek (5.3k run)
- 10km tek (10k run)
- 10km nordijska hoja (10k nordic walking)
- 21.1km polmaraton (half marathon)
- 42.2km maraton (marathon)
The start and the finish are at Zdravilišče Radenci, a spa resort with thermal indoor and outdoor pools.
Both the half marathon and the marathon are mainly-flat single-loop courses through fields and villages and through the spa town of Bad Radkersburg in Austria, which offers, like Radenci, relaxation in thermal pools.
