After returning back to England he and Lee Rickler have promoted unicycle hockey a lot in Great Britain. It was linked in some way with Telethon '88, which was some kind of national charity week. Fooltime, the circus school in Bristol, provided T-shirts to identify the teams. There were around a dozen teams if I remember rightly. I remember watching Pedro practicing afterwards, bowling an ultimate wheel along the ground, running after it, and mounting.
Fair play is crucial for all players.
At the beginning and after each goal all players have to go to their own half. Then the game starts as soon as a player of the team in possession crosses the center line. A player may only take part in a game when riding the unicycle. After falling off he or she has to mount at the same spot, but if necessary move out of the way of play first. Throwing sticks is strictly forbidden.
