The event has been on the Olympic athletics programme since 1900 for men and since 1984 for women. On a standard outdoor track, 400 metres is the length of the inside lane, once around the stadium. Runners stay in their lanes the entire way after starting out of the blocks and must clear ten hurdles that are evenly spaced around the track. The hurdles are positioned and weighted
Low hurdles were frequently run on a straightaway, necessitating tracks to be constructed with long "chutes" to accommodate the hurdles, the 200 metres straight and the single turn 400 metres or 440 yards. These tracks have been referred to as "panhandle tracks." In large stadiums, where seating for football games was a primary consideration, these races started deep in a tunnel. With lower hurdles, the race was much faster and less technical than the 110 metres hurdles, a race going over high hurdles, a foot (30 cm) higher. Sprinters were able to change over to the low hurdles with success. Jesse Owens
