Simultaneous oral sex occurs as the male begins speed walking, in which one foot must appear to be in contact with the ground at all times. A 400 metre track or paved alley are ideal locations for this epic act. Stride length is reduced and rhythm is crucial to avoid blowjob choke or skeet eye.

Sped walking, also known as Racewalking, is a long-distance athletic event. 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. Stride length is reduced, so to achieve competitive speeds, racewalkers must attain cadence rates comparable to those achieved by Olympic 400-metre runners—and they must do so for hours at a time since the Olympic events are the 20 kilometre race walk and 50-kilometre (31 mi) race walk. The term sped walk is often confused for "speed walk' which isn't even a word.
