Keiko Nogami won Japan's second straight silver in women's marathon at the Asian Games on Sunday.

Kenyan-born Bahraini Rose Chelimo built up a sizeable lead halfway into the race and was uncatchable on her way to the gold medal. The world champion even conserved energy for a sprint finish to produce a winning time of 2 hours, 34 minutes and 51 seconds.

A day after Hiroto Inoue won Japan's first gold in 32 years in the men's marathon, Nogami stayed clear in the second pack from the 25-km mark, with the race for second eventually turning into a two-woman competition between her and North Korea's Kim Hye Song.
