Defending champs John Korir, Sharon Lokedi repeat at Boston Marathon. Korir breaks course record

Defending champion John Korir broke the Boston Marathon course record, riding a tailwind to outrun the fastest field in event history and win in 2 hours, 1 minute, 52 seconds for his second straight victory. The Kenyan broke away from the pack as it headed into Heartbreak Hill in Newton and opened a 40-second lead, peeking behind him as he went through Kenmore Square with a mile to go. Sharon Lokedi joined her fellow Kenyan as a back-to-back champion, winning the women’s race in 2:18:51. Marcel Hug of Switzerland won his ninth wheelchair title in 1:16:06. Eden Rainbow-Cooper of Britain won her second women's wheelchair title in Boston.
