Graeme Obree said he was looking forward to the charity ride

The Bikeathon took place at Glasgow's Kelvingrove Park on Sunday morning and was organised by the University of Glasgow and Leukaemia Research.

Money raised will be used for a new research centre at Gartnavel hospital.

Speaking before the event, Obree, 38, said he was looking forward to the charity cycle and urged people to get on their bikes.

The cyclist, also known as The Flying Scot, holds the one hour record on a bike that he designed himself with parts of a washing machine.

Obree told BBC News Online Scotland: "I had planned to help out Alistair Campbell (former Labour Party communications chief) in London during his triathlon fundraising efforts, but couldn't manage it.

"So this opportunity makes up for it and really is a great idea."

Organisers said 420 riders signed up and they hope this year's fundraising event will eclipse the �33,000 raised last year.
