Organisers of the Belfast City Marathon have issued a statement after concerns were raised over the length of the new route.
This year the race was moved to a Sunday for the first time and the route was altered to start at Stormont and was deemed "faster and flatter".
But numerous runners raised concerns over whether the route was in fact 26.2miles or longer when they finished earlier today.
