A marathon is 26.2 miles, so a half-marathon is 13.1 miles, unless you ran one in Bangkok on Sunday, where runners had to find an extra reserve of energy as an organizer's mistake added nearly four miles to the trek.
The Jogging Association of Thailand apologized on Monday, admitting that a misplaced sign tacked on an extra six-plus kilometers for participants, which runners found understandably upsetting, according to The Associated Press.
The marathon's Facebook page filled with comments on Sunday and Monday from runners who called it "ridiculous", a "massive miscalculation" and "incredibly dangerous" for runners who had trained to run just 21 kilometres.
Asiancorrespondent.com reports that the organizations Facebook page has also seen several runners take a humorous look at the mistake, with one commenting “the organizers raised the price and gave an extra 7kms free.”
