If you live in the remote parts of Sukhumvit, far away from the comforts of Benjakitti Park, and struggle to find nice airy spots to go for a run, then the new “sky running track” at True Digital Park (Sukhumvit Soi 101) should be right up your alley—and it's free. They call it a “sky running track” because the course is elevated above other areas of the building, but, don’t get confused, it’s not like you are jogging around the top of a skyscraper. 
Named “101 Track”, the space features a 540-meter running course in a semi-outdoor space, with nothing but large metal beams covering the sides and roof. There are three different zones to match your running pace: gray for warm-ups, green for walking and jogging, and blue for full-on running if you are a real mad lad. There are also toilets, showers, and lockers available so your after-jog beer with friends isn’t ruined by the smell of your sweat session. 
101 Track. True Digital Park. Sukhumvit Soi 101. Open 7am-9pm. 
Correction: A previous version of this article mistakenly claimed that the 101 Track was pet friendly. True Digital Park is pet friendly in many areas, but the 101 Track does not allow pets.
