While running the Marathon you run through two countries (Slovenia and Austria) and you cross the border 4 times.
This is the oldest marathon, not only in Slovenia but in all of south-eastern Europe. All tracks are officially measured by AIMS/IAAF. They are run on flat terrain between fields and villages along the river Mura.
As a participant describes the event: “One of the last running events with heart and soul” Three Hearts Marathon (Slovene: Maraton treh src) is a marathon, organised in Radenci in Slovenia. It has been taking place since 1981 and attracts several thousand people each year. In addition to the marathon, a half marathon (21 km), recreative running (10 km) and a course for juniors and teenagers are organised. The event was the Slovenian national championships race from 1992 to 1998 and has hosted the national race in even-numbered years since then, now sharing the honour with the Ljubljana Marathon.
