The hot weather and high humidity were not enough to scare the more than 11,000 runners that took part in the sixth Rio de Janeiro International Half-marathon. The competition was dominated by the Kenyans, who won both the male and female races. 

Among the men the winner was Philip Rugut, who led all the race, with a time of 1:03:03. Brazilian Marílson Gomes dos Santos was second with 1:03:35, followed by the Kenyan Simon Biwot. 

Anne Jelagat won the female race in 1:13:49. She left behind Brazilians Maria Zeferina Baldaia (1:14:22), Marcia Narloch and Selma dos Reis.
