THOUSANDS of runners fell short of completing the full distance in the Sunderland marathon and half marathon events after an organising blunder.
Organisers have confirmed only the winner of the Marathon of the North last month completed the full distance.
All other runners took an accidental short cut as a result of a marshalling cock up missing 264m of the route.
The error was uncovered in an investigation launched over timings and length. Organisers have apologised and offered all runners affected by the error a 25 per cent discount on other events.

“We are sincerely sorry for any confusion and frustration that this has caused.”
As a goodwill gesture, organisers are offering all affected by the course detour a 25 per cent discount from any of next year’s events.
The statement added: “We will contact runners again at a later date, before entries open, to advise them on how to activate this offer.
“The support that runners from near and far have given our events is greatly appreciated and we hope this will not deter them from entering in the future.”
