Organisers of the Brighton Half-Marathon have apologised after participants ran 500 yards longer than the advertised distance.

About 7,500 runners took part in the 13.1 mile race through the streets of Brighton and Hove yesterday.

But, after dozens of complaints about the distance, organisers have admitted there was a human error with the placing of turn-around point between the four and five mile point in Roedean, Brighton.

This meant participants actually ran 13.42 miles - about 500 yards longer than the official distance.

A statement issued on behalf of the Race Director said: "We take full responsibility for this human error and would like to issue our most sincere apologies to all the runners who experienced disappointment over this.

"We have taken all feedback into account, we will be implementing some new additional measures ready for the 2013 race to prevent this from happening again."

Action has been taken to amend the runners' times on the Brighton Half Marathon website, taking the extra distance into account.

This will be live on www.brightonhalfmarathon.com at 4pm today (February 20) in the results section.
