SUBIC – Continuing what is turning to be an annual tradition in the Ironman weekend, triathletes stripped down to their undergarments and took part in the second Century Tuna Superbods: The Underpants Run on Saturday morning in Subic Bay.

With only their undies and sunblock on, the participants trekked a three kilometer-long route, going to and from Subic Bay Yacht Club  along the scenic Freeport Zone.

Inspired by the Ironman tradition observed in Kona, Hawaii, men and women of all ages, and even a pregnant woman, completed the short run in an appetizer for the Century Tuna Ironman 70.3 race slated on Sunday.

Aside from Ironman participants, 18 Century Superbods finalists also joined in the fun, wearing crazy accessories to match their undies.
