Race walking is a progression of steps taken in such a way so as to ensure that the walker is in contact with the ground at times, without any visible loss of contact to the human eye.
The advancing leg has to be straightened, i.e., not bent at the knee, from the moment of the first contact with ground until the vertical upright position.
If a judge observes an athlete failing to comply with the rules, the judge sends a red card to the chief judge.
When three red cards for a specific athlete are sent by three different judges to the chief judge, then that particular athlete is disqualified.
