Graham walked one-and-a-half miles through the mud of the Humber, whilst battling strong currents, hoping to beat BBC's Top Gear presenter, James May, who travelled the long way round the Humber, albeit in an Alfa Romeo!

MUD, SWEAT AND GEARS!
James took on the 47.9 miles of roads and traffic, whilst not being allowed to break the speed limit, use the Humber Bridge or use a satellite navigation system.
Speaking before the challenge, James said: "Everyone wants to know the quickest time to get across [the Humber] without using the bridge - do you walk across in a diving suit or do you use an Alfa Romeo? "I'm not confident and I have a very bad sense of direction."
Graham went on to narrowly beat James!
