“This was definitely the toughest marathon I have ever run.”

The writer ran Radenci's 42 km while feeling unwell. Although it became very difficult from the halfway point, they wrote that family and the support carried them to a 3-hour-10-minute finish.

Mats LiljegrenRan in 2013 · Finish time 3:48:05

“After 3 hours 48 minutes 5 seconds, I passed finish. I was satisfied simply to have completed the race.”

Mats Liljegren finished the 2013 Three Hearts Marathon in 3:48:05, despite taking a month off running after an injury. He experienced a flat, two-lap course, ample aid stations, quiet stretches, and wind, and felt the race was well organized.

Efter 3:48:05 korsade jag mållinjen, nöjd för det första med att över huvud taget ha kunnat genomföra tävlingen.

The Three Hearts Marathon is held in the Slovenian spa town of Radenci,

with the park in front of Hotel Radin serving as both the start and finish area.

The 45th edition will take place on Saturday, 15 May 2027, with full marathon, half marathon, the 10km race, and the 5.316km race starting on the same morning.

The event takes its name from a relay in which one full marathon runner, one half marathon runner,

and one 10km runner each run part of the marathon course, with all three crossing the finish line together.

Course passes two roundabouts in front of the hotel, turns towards Petanjci, then runs through Tišina, Tropovci,

and Gradišče before continuing through Vanča vas, Rankovci, Gederovci, Sodišinci, and Murski Petrovci and returning to Radenci.

It is an approximately 21km loop.

Full marathon follows the same loop twice, turning onto the main road again just before the finish.

The course is flat course, so full marathon total elevation gain is only 122m, and the start area is at an elevation of 198m.

It is officially measured by the Association of International Marathons and Distance Races (AIMS) course.

At the 44th edition in 2026, thousands of athletes took part, and both the men's and women's full marathon course records were broken.
