Winter triathlon

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.

Since 2013 the International Triathlon Union created a new version of the sport, which consist of 5 km of snowshoeing, 12km of ice skating and 8km of cross-country skiing. It is called winter triathlon S3, because the three sports start with an S (snowshoes, skate, ski). The first ITU event was held in Quebec, Canada in February 2015.

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