What is "winter triathlon"

n. a multisport composed of a three-sport three-leg race involving snowshoeing, ice skating, cross-country skiing

Winter triathlon is a multisport event involving the continuous and sequential completion of running, mountain biking, and cross-country skiing, all on snow. Course distances are set on the day of the event to achieve a winning time of around 80–90 minutes, after taking account of the snow conditions.

Alternatively, the sport can include skating instead of mountain biking.

The sport was denied inclusion in the 2014 Winter Olympics in Sochi, Russia.
