An amazing video has emerged from London of a man in a gorilla costume crawling across the London Marathon finish line almost a week after the race began.<br /><br />Metropolitan Police Officer Tom Harrison, who goes by the name of Mr Gorilla, crawled the entire 26.2-mile route.<br /><br />He was greeted at the finish by members of his family and handed a trophy by celebrity environmentalist Bill Oddie.<br /><br />The 41-year-old Londoner slept at friends' houses in the evenings after completing around 10 to 12 hours every day.<br /><br />He swapped between crawling on hands and knees and up on hands and feet to save his blistered knees.<br /><br />Harrison was raising money for The Gorilla Organisation, which campaigns to save the world's last remaining gorillas from extinction. <br /><br />All species (and sub-species) of gorilla are listed as Critically Endangered on the IUCN Red List.
