On 4 July 2006 Walliams swam the English Channel for Sport Relief. It took him 10 hours and 34 minutes to swim the 22-mile (35 km) stretch of sea, equivalent to 700 lengths of an Olympic-size swimming pool. This was wrongly reported as one of the top 50 recorded times for an unaided Channel crossing; in reality Walliams placed 167th at the time of crossing in only the CSA listings, excluding the CSPF listings. He raised over £1 million in donations. Under the supervision of his trainer, he trained for nine months to prepare for the swim. The training had to coincide with Walliams and Lucas's Little Britain Live tour, so he daily had to train for several hours before performing on stage in the evening. Walliams first swam from Lee-on-the-Solent near Portsmouth to the Isle of Wight in around two hours and also completed an eight-hour swim off the coast of Croatia before embarking on the cross-Channel attempt. Walliams has insisted that prior to his challenge he had never seriously taken part in any sport. The Bluetones' lead singer Mark Morriss wrote a song, "Fade In/Fade Out", in honour of Walliams' achievement; it can be found on their self-titled album, released on 9 October 2006. .
