Kenyan Jemima Jelagat Sumgong won gold in the women’s marathon yesterday in two hours, 24 minutes and four seconds after an aggressive and pre-planned surge in the final kilometres, becoming the first Kenyan woman to take the title.

Bahrain’s Eunice Jepkirui Kirwa claimed silver in 2:24:13 and Ethiopian Mare Dibaba snatched the bronze in 2:24:30.

Sumgong, 31, bided her time throughout the race, staying with the leading pack and not moving ahead until the end.

“I had prepared that I would move out at kilometre 35 and my body was responding very well, as well as my movement,” Sumgong told reporters after crossing the line at Rio’s Sambadrome, the parade ground where brightly costumed samba schools perform during the city’s annual Carnival celebration.

“It was very hot but everybody had to get through the heat,” Sumgong added.

Belarusian Volha Mazuronak, 27, shook up the pack halfway through, taking the lead and briefly pulling ahead of the lead group.

The move pushed the pace, stringing out what had been a lead pack of more than two dozen runners, causing some to drop back.

It was the first in a series of attacks by the first-time Olympian, who was ultimately unable to sustain the pace and was dropped by the leaders in the closing stages before finishing fifth in 2:24:48.
