A standard running track is 400 meters around, so 300 meters is equal to 3/4 of one lap, according to Amateur Endurance. Each lane of the track has a different starting point to accommodate for the additional length of the outside lanes.
Four laps around a standard-size track is 1,600 meters, which is slightly less than 1 mile. A track has between four and eight lanes, although a competition track needs to have at least six lanes, according to the Department of Sport and Recreation for the government of Western Australia. Tracks usually are surfaced with grass, cinder or a synthetic material.
