In one of the most highly-anticipated matchups on the track in Tokyo, Norway's Karsten Warholm narrowly edged American Rai Benjamin to win Olympic gold on Tuesday, a magnificent race in which both men smashed the previous world record by half a second – a staggering feat in an event where races are often won and lost by hundredths. Warholm posted a blistering time of 45.94 seconds. Benjamin, for his part, actually broke Warholm's old record, too, completing his race in 46.17 seconds. The narrow race between rivals represented the best of sports and produced some indelible images. Warholm was shocked to see his time and then he ripped his singlet open in excitement. Benjamin was in disbelief, as he had ran the race faster than anyone else had before but still finished with a silver medal. Brazil's Alison dos Santos earned the bronze medal with 46.72 – and he was pretty pumped about it.
