April 15 – 17, 2027 A 3-5KM Open-Water Swimming Challenge
True value isn’t found in the easy laps. It’s forged in the long effort, the deliberate choice to push through muscle fatigue, and the quiet determination required to navigate open water. Leaving the predictable black lines of a tiled pool for the vast expanse of Thac Ba Lake is a test of raw endurance.
Surrounded by over 1,300 forested islands and boundless blue water, every freestyle stroke out in the deep demands something more from you. The physical toll, the moments of self-doubt, and the sheer grit required to keep your rhythm over 5 kilometers aren’t setbacks—they are exactly what make crossing the finish line so deeply rewarding.
Whether you are chasing a new personal distance record or testing your mental limits in nature, the lake is waiting.

Open water requires you to adapt your sighting and manage a different kind of endurance, but the reward is unmatched. We provide full safety briefings and dedicated kayak escorts so you can lock into your breathing rhythm and focus purely on your stroke.
The goal is the pursuit itself. You can scale your distance anywhere between 3KM and 5KM. If you reach absolute muscle failure or need a break, our support boats are right beside you to pull you out. You can rest, recover, and celebrate the exact distance you conquered.
Bring your trusted goggles (tinted lenses are highly recommended for the sun glare), a well-fitting swimsuit that won't cause drag, and an anti-chafe balm for the long distance. We provide the high-visibility swim caps and safety floats.
Thac Ba is one of Vietnam's calmest freshwater lakes, shielded by its thousands of islands. The water is serene and free of aggressive currents, making it an ideal proving ground for long-distance efforts.
Reserve your spot now and pay the $100.00 deposit per person by bank transfer. Your spot is held while we wait for it, and counts toward the minimum once it arrives.
