The BBC will from tommorow be showing the swimming on bbc 2 at certain times and other races are shown on the red button. The diving was shown today on BBC and Tom Daley and his synchro dive partner didnt make it to a medal position today. They have only been diving together for a short while though.
Expect phelps to be awesome at this event. He looks like he has bulked up a lot for the shorter sprints and broke the 100m fly record at the US nationals.

People in the US can watch the championships via the universal sports websites
