It belongs to Tom Bosworth. I thought “I cannot even run that fast” and decided to look at the video.

While it certainly does look like they’re running, there are some severe restrictions on their movement, of course, else it’d be an event called ‘Trotting’. The rules are:

• One foot must touch the ground at all times
• The leading leg must be straight when the foot touches the ground
• It must remain straight until it passes under the torso

Judges look out any infractions by eye (no technology) and disqualify people appropriately.
