After four years Michael Phelps and Ryan Lochte will have another chance to swim for gold as the 2012 London Olympics will feature swimming in Saturday's action.
The swimming heats will kick off at 5 a.m. ET./10 a.m. GMT.
If Phelps qualifies for the 400 IM, he could be one gold medal away from tying the record for the most gold medals captured by a single Olympian. Gymnast, Larisa Latynina, from the Soviet Union captured 18 gold medals in the 1950's and 1960's.
