BBC Radio Leeds breakfast show presenters Adam Pope and Katherine Hannah are into the final day of a 127-mile pedalo trip down the Leeds-Liverpool canal.
They’ve already raised around £30,000 for Sport Relief, almost trebling their original target.
Their pedalo – in the shape of a swan – has a maximum speed of 2mph and has been kitted out to be able to broadcast live links back to the station so that listeners can follow the pair’s progress.
Along the route of the canal, well-wishers have turned out to support Adam and Katherine and donate money to the BBC appeal.
You can follow their progress and see pictures on the Grace The Swan twitter feed.
