Olympic Canoeing trials - in pictures

The purpose-built rapids at Lee Valley will be the scene of Olympic glories in just three months' time. But before then Britain's prospective Olympians must earn their place in the GB squad. There are four categories to play for: men's and women's singles kayak (K1 class), men's singles canoe (C1 class), and men's double canoe (C2 class).
