In my city you can exercise on the beach comfortably. Running for sand near the sea, under the sun and with the sea breeze is a wonderful experience. I have enjoyed it, there the humidity disappears and makes the exercise more comfortable, but in the center of the same city it is impossible to walk without sweating because the humidity is higher. You are in shape because you ran many kilometers in a short time, only in Thailand you have the weather factor against you. Greetings, @gooddream.
