Double Paralympic gold medallist Darren Kenny battled through the pain barrier to smash the world one-hour record in Manchester on Saturday.
Kenny won two golds and a silver in Athens
The Bournemouth athlete clocked up 41.817km, breaking the previous class CP3 mark by 1.7km.
"Once I'd passed the old world record I didn't really care how much further I went," said Kenny. "It was horrible.
"I just wanted it to end. Had I known how unpleasant it was I might not have been quite so keen to do it."
Fellow Briton Tom Evans had held the old record for almost 10 years.
Kenny claimed gold in Athens in the CP3 3km individual pursuit and the 1km open time trial as well as silver in the CP3 individual time trial and road race.
Kenny is keen to build on his Paralympic successes in 2005 and is aiming to compete in the inaugural Paralympic World Cup in Manchester in May.
He will also be in action at the World CP Games in Connecticut in the USA in July and the European Championships later in the summer.
