Wachirabenchathat Park (Rot Fai Park)

You find deep shade and a wide running lane on this 3 km loop in the Chatuchak park trio. Staff open gates at dawn and direct bikes to a separate circuit, so runners get clean space for steady work. Bridges and small rises add variety without killing your rhythm. Birdsong and pockets of garden scent lift the mood as the city wakes up. Water points sit near the sports fields, and toilets stay open through the morning. Reach the park fast from BTS Mo Chit or MRT Chatuchak Park, then add laps if your plan calls for a long run. Finish by walking a cool-down lap under the trees.
