Spain's David Cal paddles his canoe single (C1) during a training session on the River Lerez in the city of Pontevedra May 17, 2012. Cal is months away from a shot at winning a fifth Olympic medal, which would make him Spain's most decorated Olympian. The man who had the honour of carrying the Spanish flag at the opening ceremony in the Beijing Olympics competes in the C1 class canoe, where the competitor kneels in his craft and uses a single paddle down one side.
