Jonathan Brownlee : (2) " The triathlon can be a very hard sport to train for. You see all the time when people try to improve – like their swim, for example: they train really hard for two to three weeks, and then when they go back to normal training, the swim goes back to where it was before. " - Jonathan Brownlee " In a triathlon, it’s all about cycling in the most efficient manner. You need to save your energy for the run at the end, so you want to ride really efficiently and not waste your energy. The only way to do that is to spend a really long time on the bike.
