The swim starts at the Subic Bay Boardwalk beach fronting the Waterfront Road. Participants will do a two loop anti-clockwise format which begins with a straight 750 meters,  followed by a left turn for 400 meters, then a final 750 meters left turn bringing them to the beach area.  Upon exiting the swim course, participants will proceed to the start line and complete the second loop.  After completion of the second loop participants will exit and head to the transition area,  to start the bike course.

Please note that a key change to the swim course at IRONMAN Philippines this year is the removal of lane lines. This is to align with global IRONMAN racing standards. The swim course will be clearly marked with buoys and there will be plenty of swim marshals and officials in and out the water to maintain the integrity and safety of the course and provide support for all athletes if required.
