Racewalking, or
race walking, is a long-distance discipline within the
sport of athletics. Although it is 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, making it the most subjective of the disciplines in athletics. Typically held on either
roads or on
running tracks, common distances vary from 3000 metres (1.8 mi) up to
100 kilometres (62.1 mi).
