Biathlon

From WikiRun

Biathlon is a term used to describe any sporting event made up of two disciplines. However, biathlon usually refers specifically to the winter sport that combines cross-country skiing and rifle shooting. Another popular variant is summer biathlon, which combines cross-country running with riflery, and also modern biathlon and biathle, which combine running with swimming. Competitions involving running-biking-running are also called Duathlons to avoid confusion with the shooting events.
