Jonathan Sheppard of Tory Radio fame is running the London Marathon at the moment.
Unbelievably he is Twittering as he runs. Jonathan is not a man of, shall we say, lithe proportions so the fact that this is his third marathon in aid of St John Ambulance says much about his character.
He's a great guy and I hope he finishes more quickly than he thinks he will. Jonathan has raised £1200 for the charity already. If you would like to spur him on in the second half of the marathon click HERE to donate. He's only £60 short of his target.
UPDATE: Jonathan's latest Twitter update: "Guy pushing a wheelchair passed me! Thatll teach me to twitter."
