Ever wondered what it’s like to surf a wave for up to 50km? Well get yourself over to the British countryside region of Gloucestershire, where a natural phenomenon by the name of the Severn Tidal Bore takes occurs. Caused by rising tides moving into the funnel-shaped Bristol Channel, the waves which form get bigger the further upstream they travel.
This phenomenon has given birth to a unique surfing experience, surfers jump in and out of cars and boats as they chase the wave up stream in the attempt to surf it as many times as possible, every bore tide brings together an unusual band of inland surfers who are obsessed with riding the longest wave in Britain.
