Adam Peaty is one of the fastest men in a swimming pool in the world. The young man from Great Britain made his Olympic swimming debut on Saturday and in the event where he was the world-record holder -- 100-meter breaststroke -- Peaty topped his own best performance ever.

Not only did he easily qualify for the semifinals later on, but Peaty crushed the field and beat the world record for the competition.


Peaty will have to place well later on to make it to the medal round of the competition.
