Heart Breakfast with Jamie & Lucy 6am - 9am
When Jamie first heard that David was swimming the River Thames he thought "How hard can it be?". Then he realised it was the length - not the width!
He's not feeling too good, as he's swallowed a load of river water. He exclusively phoned in to Heart Breakfast this morning about his challenge.
David's currently on day 4 of the 140 mile journey. He started out again today at 7am in Wallingford.
