U.S. swimmer Michael Phelps blasted a new world record to defend his title in the event, and more importantly, claim his first Olympic gold, seventh career, and ninth overall. Phelps expected to get a major challenge from teammate Ryan Lochte, but he pulled away from the field on the breaststroke leg, and then opened up his lead on the freestyle leg to a strong finish in 4:03.84, more than a second faster than his world record from the U.S. Olympic Trials.[2][3] Hungary's László Cseh earned his first ever Olympic silver medal at these Games, in a European record of 4:06.16. Lochte, who fought off a challenge against Phelps, faded towards the end of the race with a bronze in 4:08.09.[4]
Italian tandem Alessio Boggiatto (4:12.16) and Luca Marin (4:12.47) earned fourth and fifth spots with only 0.31 seconds apart from each other. Hungary's Gergő Kis (4:12.84), Canada's Brian Johns (4:13.38), and Brazil's Thiago Pereira (4:15.40) rounded out the finale.[4]
