I think this is easily the best place to run in bangkok, long distance or short distance they have so many runtracks, not only that they have a really nice, green and peaceful Skywalker for getting away of the hustle and bustle of bangkok city, surrounded by a lot of beautiful gardens and lakes , such as a botanical museum. Even just for a walk, you can spent your whole afternoon here exploring this big park, with gym, basketball and football field, exercise machines. Also they keep the place very clean and maintained. Dont forget to bring mosquitoe repellent, because youll find many many mosquitoes, wich is pretty normal for nature, there were also squirrels everywhere and dragonflies. You could also rent a small boat to chill on the lake .
If I could improve something, make all the drinking fountains workable, not only decoration.
