(UPDATE) RIO Olympics bronze medalist Henri Schoeman and Els Visser of the Netherlands showcased their dominance in the waters and the challenging terrain of the Ironman 70.3 Lapu-Lapu, emerging victorious in an exhilarating display of endurance and skill in Mactan Sunday.

The duo sustained their form all the way to the finish, securing wire-to-wire triumphs in the premier category of the 1.9k swim-90k bike-21k run race presented by Megaworld The Mactan Newtown.

Each pocketed $5,500 for their remarkable performances.

Barely emerging on top of the swim (00:24:15), Schoeman established a commanding lead of nearly three minutes over Bishop and Osborne after an impressive bike leg (02:08:48) and enduring the punishing run (01:24:29) in scorching conditions to claim the title in 04:02:31.

Osborne outpaced Bishop in the closing run and took runner-up honors in 04:06:40 with leg times of 00:25:44. 02:10:44 and 01:25:12, while Bishop settled for third in 04:11:01 with leg clocking of 00:25:18, 02:10:54 and 01:29:10.

Aussie Caleb Noble placed fourth in 04:13:47 followed by Calvin Amos, also from Down Under, (04:15:19), Chinese-Taipei's Tuan Chun Chang (04:18:42), Aussie Nathan Dortmann (04:19:05) and UAE's Luke Mathews (04:21:10).

Denmark's Daniel Bakkergard, one of the pre-race contenders, didn't start due to back pains.

In the women's pro division. Visser finished with a time of 04:21:29, triumphing over Germany's Anne Reischmann (04:24:39) and Hungary's Zsanett Bragmayer (04:36:41).

Visser, runner-up in the recent Ironman New Zealand, delivered an impressive performance in the swim leg, clocking 00:29:53 and building an early cushion over Reischmann, a consistent Top 10 finisher in the last three World Championships who timed 00:32:05.

She maintained her advantage in the bike (02:18:23) compared to Reischmann's 02:19:19 and cruised to victory with a 01:28:28 clocking in the run against the latter's 01:28:23.
