Swimmers spend a lot of time in the pool, but they also train outside of the pool. Although each swim varies in length and pace, swimmers train on muscle and stamina development to add the strength and speed required to compete at such a high level. The new Olympic-sized swimming pool was meant to benefit swimmers in several ways, the first of which is an increase in the number of lanes. Increasing the lane count from eight to 10 provides the swimmers with a "buffer lane," which aids in the absorption of waves created by the swimmers' motions and allows for less resistance against the swimmers. There's no way underwater cameras could catch it, even if Olympic swimmers peed during their races, which they don't. The only way to know if someone is peeing in the pool is if they proclaim it or if they are really thirsty and sit in one location while they do it. A 10km open water 'Marathon' event was added to the Olympic swimming calendar in 2008, with English swimmers Keri-anne Payne and Cassandra Patten earning silver and bronze in the women's race, respectively.
