Until now they’ve been going head to head in the 200 free & 200 im at the world championship swimming in Shanghai (both won by Ryan btw). They have been team mates, rivals and friends for quit some time, at least that’s what i read on the net and see in clips.
If they’re not training or racing, they like to hang out and play games. You can read about it on twitter and now, thanks to Speedo, you can see it on youtube.
Maybe i’m not completely objective, but i don’t care i’m a fan & proud of it!
