The statement has been posted on the event website

Managers have promised to review arrangements for future events after a flood of complaints from participants in the 13.1 mile race.

Organisers conceded they were "under resourced in certain key areas" during Sunday's run from Ocean Terminal.

Competitors have blamed "terrible organisation" for the problems.

Runners have complained about a lack of timing chips, which meant their final time scores were higher than they should have been and a narrow space which caused a huge backlog at the start.

Others said a motorbike was sitting in the middle of participants at the start - forcing them to stop and wait for it to move.

This resulted in a long queue of runners which stretched back almost over the finish line Race participant

The course began outside the terminal in Leith and headed along the waterfront to Cramond before turning back towards the city.

One runner from London wrote on the Runner's World magazine website that he had to stop so the lead car could drive past him some 11 minutes into the race.

"It got stuck under a barrier at the back of the shopping centre where we started," he wrote.

"What a horrible place to start from too. Far too narrow. This caused such a backlog of runners trying to find some space."

Queue of runners

Another participant, from Glasgow, said: "Because there was no chip timing system, stewards were checking runners off manually after they'd finished the race.

"This resulted in a long queue of runners which stretched back almost over the finish line and people had to stand and wait for up to 20 minutes before being able to clear the area.

"This could have led to someone being hurt or standing getting cold too quickly after running more than 13 miles."

The organisers willingly acknowledge the shortcomings and apologise for the inconvenience caused to the runners Organisers' statement

Others have complained that the �20 entry fee was "grossly overpriced" for the "shambolic organisation".

In a joint statement made on runnersworld.co.uk, event director John Martindale and race director Ian Ladbrooke said: "The organisers of the inaugural Edinburgh Forthside Half Marathon acknowledge that all did not go according to plan at their event on Sunday 26 March.

"On this occasion the organisers concede that they were under resourced in certain key areas."

They said all the participants' comments would be taken into account to ensure that the problems were eliminated for next year.
