CAMARINES SUR — Some of the world’s top triathletes arrived here from Manila on Thursday, three days before the Cobra Energy Drink Ironman 70.3 Philippines blasts off at the CamSur Water Sports Complex (CWC).

Eleven-time Ironman champion Chris McCormack of Australia led the foreign professionals participating in the inaugural race, along with compatriot Peter Jacobs, seven-time world cup titlist Tim Marr of the United States and 11-time Ironman champion Lisa Bentley of Canda.

Other international triathletes who had signed up for the event include Terenzo Bozzone of New Zealand, Charlotte Paul of Australia , and Bree Wee and Gina Kehr of the US.

The gruelling race covers a total distance of 70.3 miles or 113 kilometers consisting of 1.9km (1.2mi) swimming, 90km (56mi) biking, and 21.09km (13.1mi) running.

Former RP triathlon team member and 2005 Manila Southeast Asian Games bronze winner Arland Macasieb banners the Filipino contingent led by August Benedicto, Kim Mangrobang and Monica Torres.

Macasieb, who has been competing in several long-distance races, targets a top 10 finish against the strong field.

“I’m probably behind these guys, so it’s hard to get into the Top 5,” said the 33-year-old Macasieb, who has competed in three full ironman races.

Macasieb added the windy conditions would be a challenge both to local and foreign participants and expects a fast bike leg because of the flat course.

The Fil-Am triathlete believes the presence of the world champions could motivate local athletes to beat their personal records.

“It’s the satisfaction of competing in such a challenging sport and against the best athletes in the world that will push us to the limit,” Macasieb said.
