If you fail to see the appeal of running through London while clad in a gorilla suit, this race probably isn’t for you. For everyone else, it’s a good cause and an excellent excuse to go full King Kong. Join Bill Oddie and hundreds of others for an 8km run to raise money for gorilla conservation. Bananas optional, gorilla suit obligatory. Over 14s only. The price includes a gorilla suit which you get to keep. The run is done to help save a species on the edge of extinction.
