Cherop outkicked Jemima Jelagat Sumgong to win by 2 seconds, in 2:31:50 — the fifth consecutive year the women's race was decided by a sprint down Boylston Street. Cherop, who was also hoping to be selected for the Kenyan Olympic team, was third at the world championships and third in Boston last year.
"This time around, I was really prepared," she said. "Last time the race went so fast and I didn't know I was about to finish. I didn't know the course well and I didn't know the finish line was coming."
The winners will receive $150,000 apiece. Korir and his wife, Canadian runner Tarah McKay, run a foundation in his hometown of Kitale and have been building a hospital in the memory of his brother Nicholas, who was killed by a black mamba snake at the age of 10.
One year after cool temperatures and a significant tailwind helped Mutai finish in 2:03:02 for the fastest marathon ever, the heat had elite runners adopting a slower pace and recreational runners trying to figure out how to finish at all.
Race officials warned runners to be alert for signs of heat stroke and dehydration and asked those who were inexperienced or ill to skip this race. The BAA also offered a limited deferment in 2010, when the Icelandic volcano eruption stalled air traffic in Europe and prevented about 300 runners from getting to Boston.
The Boston Marathon has had its share of hot weather, with the thermometer hitting 97 degrees during the 1909 race that came to be known as "The Inferno" and the 1976 "Run for the Hoses" that started in 100-degree heat and finished with spectators sprinkling winner Jack Fultz with garden hoses to cool him down.
Jason Warick, of Saskatoon, Saskatchewan, took an ice bath before the race to cool his body.
He finished 62nd, following his 73-minute half-marathon by a 95-minute second 13.1 miles.
"It was brutal, just brutally hot," he said. "Around 15 miles the wheels just came off. Then it was just about getting home."
