100 kilometres race walk
Men's racewalk. Walker at right appears to be illegal in that both feet are off the ground, but an infraction is only committed when loss of contact is visible to the human eye.
The 100-kilometer race walk is a racewalking event. The event is competed as a road race. Athletes must always keep in contact with the ground and the supporting leg must remain straight until the raised leg passes it. 100 kilometers is 62.14 miles.
Against the wishes of the Israeli track and field authorities, because the Munich Massacre had just taken place, Israel Shaul Ladany competed and won the gold medal in the World 100 km walking title at the '72 World Championships in Switzerland, in a time of 9:31:00.
