That was 70 seconds faster than Geoffrey Mutai’s then-world best in 2011, and the fifth-fastest marathon of all time.The top three men ⁠⁠beat the previous record.Korir said he knew he was on a record pace at the 25-mile (40km) mark, but he did not bother to check the clock as he crossed the finish line. He was informed of his accomplishment by Boston Athletic Association president Jack Fleming and jumped for joy.“When they told me I had run the course record, that’s when I started to be happy,” said the 29-year-old Kenyan, who last year joined his brother to become the first relatives to win the race. “I knew I would defend my title. But I didn’t know I could run that fast.”A relaxed Korir surged past Ethiopia’s Milkesha Mengesha at the 20-mile ‌‌(32.1km) mark to take control of the race. Korir ran alone for the final 6 miles (9.6km), breaking the record set in 2011 by compatriot Geoffrey Mutai in 2:03:02.Korir clocked his last mile of the race in four minutes and 26 seconds. Before crossing the finish line, he smiled broadly as he stuck out his tongue in a playful gesture.John Korir ran alone for the final 6 miles (9.6 kilometres) of the marathon [Natalie Reid/Imagn Images via Reuters]Meanwhile, Lokedi won the women’s race in two hours, 18 minutes and 51 seconds.
