44. Three Hearts Marathon

The Three Hearts Marathon (Maraton treh src) is a long-standing athletic event held in Radenci, Slovenia. Organized by the Sport club Three hearts, the event features a variety of running and walking distances that start and finish near the hotel Radin. The courses are governed by the rules of World Athletics (WA) and the Athletic Federation of Slovenia (AZS).

Participants can choose from several competitive and non-competitive distances:

  • Radenska Classic marathon: 42.195 km
  • Radenska Light halfmarathon: 21.098 km
  • Radenska Naturelle run: 10,000 m
  • Oaza run: 5.316 m
  • Three Hearts Run: A team event for three runners
  • Children's run: Distances ranging from 250 m to 1,000 m
  • March three hearts and Nordic walking

The Three Hearts Run is a unique trio event where three participants (male, female, or mixed) cover the marathon distance together. One runner starts the full marathon, the second joins at the halfway point (21 km), and the third joins 10 km before the finish. All three must cross the line together.

For the full marathon, a time limit of 2 hours and 30 minutes is enforced for entering the second round of the course. Runners who do not reach this point in time are directed to the 21 km finish line. Medical assistance is provided along the tracks and at the finish area. Registration includes a single-use timing chip. Visit the organization's website for the most recent information.
