Racewalking, or race walking, is a long-distance discipline within the sport of athletics. Although a foot race, it is different from running in that one foot must appear to be in contact with the ground at all times. This is assessed by race judges. Typically held on either roads or running tracks, common distances range from 3,000 metres (1.9 mi) up to 100 kilometres (62.1 mi).
