Gary Wayne Hall, Jr. (born September 26, 1974 in Cincinnati, Ohio) is an American swimmer who competed in the 1996, 2000, and 2004 Olympics and won ten Olympic medals (5 gold, 3 silver, 2 bronze).
Hall is well known for his "pro-wrestling like" antics before a competition; frequently strutting onto the pool deck in boxing shorts and robe, shadow boxing and flexing for the audience.
Hall won two individual silvers and two team relay golds at the games including helping set the world record in both the 400m freestyle and medley relays.
In 1999, Gary Hall, Jr. was diagnosed with Type 1 diabetes, commonly referred to as childhood or juvenile diabetes. Upon his diagnosis, Hall struggled with the possibilities and the effects he knew the medical condition would have on his life. Hall took a short hiatus from swimming, but returned in time to compete in the 2000 U.S. Olympic Trials. There he won the 50m freestyle and placed second in the 100m freestyle. His 50m time, at 21.76 seconds set a new American record, beating the ten-year old record set by Tom Jager.
Prior to 4x100m Freestyle Relay, Hall posted on his announced on his blog: "My biased opinion says that we will smash them like guitars. Historically the U.S. has always risen to the occasion. But the logic in that remote area of my brain says it won't be so easy for the United States to dominate the waters this time". Hall swam last in the team against Australian Ian Thorpe. Thorpe had a better start and came up a body length in front of Hall. Hall managed a lead but Thorpe fought back, ending the traditional American dominance of the event. The Australian team famously responded to Hall's remarks after the race by playing air guitar on the pool deck. Hall recalled the race saying “I don’t even know how to play the guitar...I consider it the best relay race I’ve ever been part of. I doff my cap to the great Ian Thorpe. He swum better than I did.”
The Race Club is a swimming club founded by Gary Hall, Jr. and his father, Gary Hall, Sr. The club is designed to serve as a training group for some of the world's elite swimmers. To be able to train with the Race Club, one must either have been ranked in the top 20 in the world the past 3 calendar years or top 3 in their nation in the past year. The Race Club includes such well known swimmers as Roland Mark Schoeman, Mark Foster,Ryk Neethling, Ricky Busquets and Therese Alshammar. They are coached by University of California, Berkeley coach Mike Bottom, who was the coach of Hall and Anthony Ervin before the 2000 Sydney games. The Race Club also offers various swimming camps and clinics year round for young swimmers at their Islamorada, Florida based training center.
In the summer of 2006, Hall's sister, Bebe Hall, was attacked by a Blacktip reef shark near Islamorada while she and Gary were spearfishing, an attack for which his sister needed 19 stitches. Hall repeatedly punched the shark and his sister shot a spear into it, after which the shark swam off.
