Roger Allsop is the oldest person to swim across the English Channel. He's 70 - even older than me.
On 31 August he swam across in 17 hours 51 minutes. At its narrowest, between Dover and Cap Gris Nez near Calais, the Channel is 34km (21 miles) wide, but looking at the zigzag route he took he must have covered twice that distance. As you can see from the videoclip, when he came out he was all sopping.
