Held over a weekend in late November, the full marathon starts and finishes at Sanam Luang on a closed-course loop past landmarks including the Democracy Monument, Rama VIII Bridge, Wat Benchamabophit, Victory Monument, Lumpini Park and the Giant Swing; the half marathon runs a day earlier, starting at MBK Center and finishing at Sanam Luang.
