Yep, it’s exactly what it sounds like. Strap a four-wheel mountainboard to your feet, attach a tow line to a horse and, um, get dragged along behind it. The idea is competitors race against each other round a 400m track. They say it’s the modern equivalent to chariot racing. We say it’s pretty lame excuse for an action sport. To top it off, they even have their own British Horse Boarding Association.
