The current world record was set in 2002 at the same location with a speed of 129.6km/h (81MPH) by Sam Whittingham in a custom-made recumbent bike. A lot of advanced aerospace engineering goes into these machines to reach highway speeds on under one horsepower. Take a look around their site for pictures of the event and this year's records. It ends 20 September, so more pictures and results will come."
