In 2002, Scott, who typically walked about nine hours each day, covering half a mile per hour, took only five days to complete the London and New York marathons, but set a record in 2003 because he was hit by food poisoning. "I had to keep dashing to the loo [toilet]," he explained, "and on the Royal Yacht Britannia there was a problem trying to get the suit off in time to get to the toilet..."
[Among Scott's subsequent feats? Completing an underwater marathon walk of the full length of Loch Ness wearing diving equipment and running the Edinburgh marathon in a suit of medieval armour.]
[Several competitors in the London Marathon in April 2004 with small timing chips attached to their shoe laces (and sensor mats at various points along the course) were able to send text messages to friends to keep them abreast of their progress.]
