I could not survive living in Bangkok without Rama 9 Park just a 5K bike ride away from where I live. Currently I am training for the Khao Yai North Face Trail Run coming up in February, and I can get nice long runs in at this park. It has many paths (paved, no dirt trails), and right now it is Cool Season here, so day temps are 23 to 29 and breezy - way better than running in the heat and humidity. This park is one of the largest green spaces in the city, and it is right next to a reservoir with a 4k bike track loop, which I also often take advantage of as well. Amen to Saturday and Sunday mornings outside!!
