<P> There are judges on the course to monitor form . Three judges submitting `` red cards '' for violations results in disqualification . There is a scoreboard placed on the course so competitors can see their violation status . If the third violation is received , the chief judge removes the competitor from the course by showing a red paddle . For monitoring reasons , races are held on a looped course or on a track so judges get to see competitors several times during a race . A judge could also `` caution '' a competitor that he or she is in danger of losing form by showing a paddle that indicates either losing contact or bent knees . No judge may submit more than one card for each walker and the chief judge may not submit any cards ; it is his or her job only to disqualify the offending walker . Disqualifications are routine at the elite level , such as the famous case of Jane Saville , disqualified within sight of a gold medal in front of her home crowd in the 2000 Summer Olympics , or Yet Lyu , disqualified 20 meters before the finish line at the 2017 World Championships in Athletics . </P>
