The steeplechase is an obstacle race in athletics, which derives its name from the steeplechase in horse racing. The length of the race is usually 3,000 metres; junior and some masters events are 2,000 m, as women's events formerly were. The circuit has four ordinary barriers and one water jump. Over 3,000 m, each runner must clear a total of 28 ordinary barriers and seven water jumps. This entails seven complete laps after starting with a fraction of a lap run without barriers. The water jump is located on the back turn, either inside the inner lane or outside the outer lane. If it is on the outside, then each of the seven laps is longer than the standard 400 m, and the starting point is on the home straight. If the water jump is on the inside, each lap is shorter than 400 m, the starting point is on the back straight, and the water jump is bypassed at the start. According to IAAF rules, barrier height is 914 mm (36 in) for men and 762 mm (30 in) for women.
