How race season works

  • Peak season is the cool season, roughly November to February, when the big road races and marathons happen.
  • Races start very early. To beat the heat, many start between 3 and 6 AM — check the start time and plan how you'll get there before public transport opens.
  • Registration is online, mostly through Thai platforms like race.thai.run and Runlah. Popular races sell out weeks ahead.
  • Your bib and shirt are usually collected at an expo a day or two before. Bring ID and your registration QR code.

Fun runs and 5K

The easiest way into racing. Short distances, a festival atmosphere and often themes, costumes or a cause.

10K

Half marathons

Train for it with a club

Training with a group is the easiest way to stay consistent before race day. Training-focused crews like Seuxphen Running Team and Run Now Fab Later Crew run regular sessions and often race together. Before a race in the hot months, read how to run in the Bangkok heat.
