Riders race down the beach during the Adult Quad and Sidecar race during the 2016 HydroGarden Weston Beach Race in Weston-super-Mare, south west England, on October 8, 2016. Beach racing is an offshoot of enduro and motocross racing. Riders on solo motorcycles and quad bikes compete on a course marked out on a beach, with man-made jumps and sand dunes being constructed to make the course tougher. (ADRIAN DENNIS/AFP/Getty Images)
