PHNOM PENH. — Kim Mangrobang gave her all in the final run amid the scorching heat to successfully retain the women’s duathlon title in the 32nd Southeast Asian Games here on Sunday.

After a shaky start in the 5k run start, Mangrobang picked up steam in the 20km bike leg before scooting all the way to the finish in the 2.5km run finale at the Kep Beach Resort.

The three-time SEA Games triathlon champion clocked one hour, four minutes and 25.3 seconds while Thi Phuong Trinh Nguyen of Vietnam crossed the finish line in 1:05:13.5 and bagged the silver medal.

Indonesia’s Maharani Wahyuningt placed third in 1:06:17.4.

Kira Ellis, Mangrobang’s teammate, checked in fifth (1:07.13), the same finish of Filipino-Spanish Fernando Casares, who missed out on a podium finish in men’s duathlon.

Mangrobang attempts to make it four in a row in women’s triathlon on Monday in a much-awaited duel with Cambodia naturalized athlete Margot Marabedian, a former French triathlete who ruled the women’s aquathlon sprint last Saturday.

Cebuano Andrew Kim Remolino earlier claimed a silver medal in the men’s aquathlon.
