Then he quickly downs a soft drink for the energy rush he needs for fencing. He needs to be on his feet and fully alert. At the Olympics, the 24 athletes will fence every other in a round-robin event. Senior says he is more relaxed about the 200m swim. He aims to grab the lead after the first 50m and hang on to it.
Most pentathletes think the next event, the showjumping, is more about luck than skill.
Senior says it's hard to prepare for as competitors must ride the horse they draw at random. They get 20 minutes to warm up with the horse and are then sent into the showjumping ring. The final stage, the 3km cross-country run, is one of Senior's strongest. It's a staggered run, so the winner of this event is the overall winner. Senior says the different events will make it hard to pick a winner in Sydney.
