2008 — Usain Bolt helps Jamaica win the 400-meter relay final in 37.10 seconds for his third gold medal and third world record of the Beijing Games. Bolt becomes only the fourth man, and the first since Carl Lewis in 1984, to win all three Olympic sprint events. Bryan Clay wins the decathlon, the first American to win the 10-discipline event at the Olympics since Dan O’Brien at Atlanta in 1996.
