People in the centre of London may have been forgiven for thinking they had gone bananas and were seeing things over the weekend - but it was just animal fancy dress. Around 700 people took part in a sponsored run for the Great Gorilla Organisation and every single one sported gorilla fancy dress to raise awareness for the good cause. Conservationist Bill Oddie fired the starting pistol for the 4.3-mile race, which saw participants run from Minster Court to the City, Tower Bridge and the Tate Modern. The number of runners was quite poignant, as it represents the approximate number of mountain gorillas left in the entire world. It is hoped that as much as £250,000 could have been raised for the Great Gorilla Organisation by the time all the sponsor money has come in during mid-November. This is certainly a great way to generate vital funds for a good cause, although it is probably better to don hairy suits at this time of year than in the summer! Why not try your own animal-themed fun run?
