Nai Thon Beach

Pick a quiet, scenic out-and-back with a mild slope and clear water. Nai Thon runs for about 1 kilometer, which suits threshold sets, repeats, or a short progression at sunrise. Park near the central village strip, step onto the sand, and target the compact band along the waterline. The camber stays mild, and the beach sees light traffic at first light, so you can lock into form without dodging chairs or carts. If you want more distance, add a paved climb on the road toward Nai Yang or tack on repeats across the bay with short walk recoveries. Finish with a swim over the reef at the north end on calm days. Bring water, as the small shops open a bit later than in the larger resort areas.
