In the his first event of the Olympics, Michael Phelps is already golden. The 19 year-old swimmer is attempting to win seven gold medals and tie Mark Spitz's record of seven gold medals in one Olympic games. Spitz's record dates back to the 1972 Munich Games. The most medals of any color won in a single Olympics is eight by Aleksandr Dityatin of the Soviet Union in 1980.

In today's race, Phelps broke his own record in the 400 meter individual medley. The 400m IM, is a four discipline race where the swimmer completes one 100 meter lap in the butterfly, backstroke, breaststroke, and finally freestyle. His time in the race was 4:08.26, .15 second faster than the world record that he set earlier this year. The record is more than three seconds better than Tom Dolan's record of 4:11.76 set four years ago at the Sydney Games.

Erik Vendt, Phelps's teammate, came in second, more than 3.5 seconds later. The silver repeats his 2000 performance in the 400m IM. Laszio Cheh of Hungary won the bronze medal.

Phelps has at least six races remaining, the 200M freestyle on Monday, the 100 and 200m butterfly, the 200m IM, the 800m freestyle relay, the 400m medley relay. It's also possible that he races in the 400m freestyle relay.
