Lifting and creeping

Explanation:

Race walking is an olympic sport that is often a resistance sport, the categories vary from 3km to 100 km, and reasons to be disqualified are lifting both feet at the same time, because that would be considered running and creeping which states that the front leg should be straight at the moment of touching the ground, otherwise it would be considered running, so the only two rules are that one feet must be in contact with the ground at all times, and the front leg must be straight at the moment in wich it touches the ground.
