Three competitors run marathon, half-marathon, and 10 km on the same course, finishing together.
Three competitors participate (they can be male, female, or mixed). One runs the marathon distance, another runs the half-marathon distance, and the third runs 10 km. All distances take place on the marathon course of 42.198 km.
The marathon runner starts at the marathon distance. At 21.098 km, the next runner joins this runner, and 10 km from the finish line, the third runner joins them. All three runners must cross the finish line together. The times for each individual (42 km, 21 km, and 10 km) are recorded separately, not as a combined result, except for the marathon runner. The fastest three trios (regardless of the gender of the competitors) will receive trophies. There are no cash prizes for the trios. In the event of setting national, European, or world records in the marathon, these will not be recognized. Transportation to key points on the course will be organized.
