The third annual office chair racing championships have just been held in Bad Koenig-Zell, Germany.
Competitors are allowed to fit inline skate wheels and handles to their chairs, but nothing else - particularly no motors! Safety attire, including crash helmets, is encouraged, and fancy dress is permitted. This year's winner of the 'best-designed chair' award was Heiko Winter, who fitted his chair with a horse's head and a saddle, and rode it dressed as a cowboy.
The overall winner this year was Pierre Feller from Luxembourg, who completed the 600 foot run in just under 27 seconds. Here's footage of this year's event.
Looks like everyone had fun!
