Michael Phelps is gearing up for a weekend showdown with Paul Biedermann at the World Cup in Berlin. Biedermann beat Phelps in the 200 freestyle in August.
Phelps wore the old style bathing suit, just shorts, about to become regulation again. No more full body speed suits, as they've been banned starting next year.
Below are a few pics from the meet, including his face when he lost.
