Benchasiri Park

You get a compact 700 m loop steps from BTS Phrom Phong. Trees ring the lake and give steady shade, and the flat path suits short intervals or a recovery run before work. Staff open gates at dawn, guards keep watch, and tai chi groups share the space near the sculpture lawn. Water points and clean toilets sit by the playground. Add volume with block repeats or hop to Benjakitti for a longer session if time allows. Office towers rise around the park, so you feel a hush at first light that fades as the shops open. Exit the gate and grab a cold drink on Sukhumvit.
