Chattanooga Sports Committee President Tim Morgan says course was certified. He says the mishap was a ‘‘human error,’’ with someone placing a turnaround marker two blocks too early.

CHATTANOOGA, Tenn. — Officials say a mistake caused the Chattanooga Marathon to fall short of its full 26.2 mile course.

The mistake invalidates the times of any of the 529 full marathon finishers who hoped to use their Sunday performance to qualify for other races, including the 2017 Boston Marathon.


Boston Marathon spokesman Jack Fleming confirmed Sunday’s Chattanooga results are not relevant to next month’s race. All qualified runners for this year’s marathon posted their qualifying performance between September 2014 and September 2015, said Fleming in a statement.

Fleming said the Boston Athletic Association, which organizes the marathon, has requested more information from the Chattanooga race organizers.

“We’ll have to understand the circumstances so not really anything additional we can say at this point,” said Fleming in an e-mail Thursday.

Scott Bush, director of communications for Running USA, says in most cases, the race director of an invalidated race must seek waivers on behalf of participants wishing to use their times to qualify for future races.
