Office Chair Race World Championships pulls in the crowds in Solothurn
Switzerland has played host to the rather specialised World Championship Office Chair Race this weekend.
People lined the streets of Olten in the canton of Solothurn to cheer on participants as they negotiated their way around barriers made of hay bales in office chairs, skilfully using their feet for control.
The racers were mostly Swiss with some from Germany and Austria. Many were wearing costumes and a there was a wide range of chairs, all on rollers.
The grand prize was a travel voucher worth CHF 500.
