Get your Speedos ready. The Singha Cha Am Bikini Beach Run is back. This raucous 5k, 10.5k, and 21k traces the shoreline of Cha Am in the early hours, while the hoi polloi still sleeps off the previous night’s beachfront parties. The race finishes on the beach at about the same time as the sun rises, a cadre of sweaty runners clad in swimwear labouring down the sloped sands. It’s fun, in other words.
