RIO DE JANEIRO — The 200-meter individual medley field was chasing Michael Phelps, who was trying with every freestyle stroke to pass Leonidas of Rhodes.
Leonidas won 12 individual events over four Olympics. At 36, five years older than Phelps, he won his last three golds in 152 B.C, in races of about 200 and 400 meters and in a shield-carrying race. It wasn’t easy, but Phelps surpassed Leonidas, winning his 13th individual gold (and 22nd gold overall and 26th medal). With the victory, Phelps also joined the track and field Olympians Al Oerter and Carl Lewis as the only Americans to win an individual event four times.
