Half-marathons—the slightly more palatable version of full-length marathons—are supposed to be 13.1 miles (21 km) long—but a recent race in Thailand was unintentionally quite a bit longer. Due to a mapping mishap, runners in the Standard Chartered Bangkok marathon last Sunday were subjected to an extra-long run: almost 17 miles, or 30% longer they had trained for.
The Jogging Association of Thailand apologized on Monday (Nov. 16), saying, “It will not happen again in the future.”
The marathon’s Facebook page was flooded with comments criticizing the race as “ridiculous,” a “massive miscalculation,” and “incredibly dangerous.”
