Winter biathlon athletes created this summer version to maintain their training during the warmer months, combining running with rifle shooting. The event features three running segments—1500 meters, 2000 meters, and 1500 meters—interrupted by two shooting rounds where participants fire five shots at knock-down targets, first from a prone position and then from standing. Runners start in pairs at one-minute intervals, matched by similar 5K times to keep the shooting range uncrowded, with scorers tracking each person's hits.
