Skiathlon is a cross‑country skiing race that combines two techniques—classic and freestyle (skating)—in one continuous event, with a ski change in the middle.

What is skiathlon?

In a skiathlon, all racers start together in a mass start and ski the first half of the distance using classic technique (parallel skis in prepared tracks).

At roughly the halfway point, they enter a special pit area, quickly change to skate skis and poles, and immediately continue the race in freestyle/skating technique.

The winner is simply the first athlete to cross the finish line after the full combined distance.

Typical distances

  • International level: 2 × 10 km (total 20 km) for both men and women in major championships since recent rule changes.
  • Lower levels or local events: can range from about 10 km up to 50 km total, depending on the competition.

Why fans like it

  • Requires endurance plus technical skill in two different styles.
  • The mid‑race equipment change adds tension and “pit stop” drama—small mistakes can cost a medal.
  • Because everyone starts together and tactics matter, it often produces attacks, comebacks, and tight finishes that are exciting to watch.

A simple way to think of it: skiathlon is like a biathlon of techniques instead of shooting—one race, two styles, and no break in between.
