PHOENIX, Arizona, June 11. THE Wednesday edition of The Morning Swim Show highlights a relatively new Olympic event and visits with a former collegiate diver who parlayed his talents into high-diving spectacles.

Today's Reaction Time previews the race for the Olympic medals in the women's 800 freestyle relay, which will be contested for only the fourth time in the Games. Swimming World senior writer John Lohn talks about the possibility that the gold medal team will have to swim a sub-7:48 to win the event, and offers a few names that could be on the team for the United States, Australia, Great Britain and France.

One of the people in contention for a spot on the USA team is Lacey Nymeyer, who is on the world-record-setting team from the 2007 world championships. Nymeyer talks to host Peter Busch about that relay, how much she loves swimming on relays and the competition in the 100 and 200 frees at the upcoming Olympic Trials.

In the For the Record segment, Bruce Wigo talks to Chip Humphrey, the 1980 Acapulco Cliff Diving champion and a founder of a company that does traveling high-diving shows. Humphrey talks about his introduction to diving at a YMCA in New Jersey, then going to college at the University of Miami, where he learned much more about diving from coaches and teammates. From there, he traveled to 22 countries with high-diving shows, competing in cliff diving competitions in the 1970s, 1980s and 1990s.
