The London Marathon started on 24 April but Tom Harrison, one of the participants, was able to finish it only by 29 April.
It's not that he's a slow runner. It's just that he crawled through the race. Yes! Harriason crawled through the race wearing his gorilla suit.
The man dubbed Mr Gorilla is raising money for the Gorilla Organisation. So far more than 22,000 pounds (28,500 US dollars) have been pledged. The 41-year-old crossed the finish line with his two sons walking beside him on Saturday.
Harrison says the money will be used to protect endangered gorillas in Africa.
