About 3.8% Short 

Whoops.

Athletes who ran the recent “City Half” course in San Francisco might have thought they’d run the fastest half-marathon of their lives. Alas, that was not correct, as noted in an email race organizers sent to short-changed participants:

“It came to our attention that, despite being measured and certified by a USAFT-certified course measurer, the course was incorrectly measured, resulting in a length of 12.6 miles instead of the full 13.1 miles,” the email read.

Though there were apparently no mentions of refunds or other recompense, organizers did include this:

“Thank you for running with us, and despite this error, we hope you enjoyed the course.”

I think most racers would have been much more likely to enjoy the course if it had been the proper distance.
