Vitality Brighton Half Marathon organisers have released a statement this morning announcing that their 2015, 2016 and 2017 race courses have been short, following concerns raised by UK Athletics.
The statement reads: 'Over the past few weeks we have been conducting a formal investigation into this matter and can now confirm that unfortunately the course has been short by 146 metres (0.09 miles) for these particular race years.
The area of concern centred on the turning point just after mile 4 where the course passes Roedean School before turning and heading back towards Brighton.'
The concerns were raised following an analysis of GPS data from runners and procedures around how the course was set out for the races.
Simon Dowe, CEO of the Sussex Beacon, the charity which organises the race, comments: 'We can’t apologise enough for this mistake. I know it’s hugely disappointing to everyone who trained so hard. I also know that for some, the news will be devastating as it affects race times, personal bests and records. Our thoughts are very much with the runners. I’m so sorry that their remarkable achievements and the money raised for good causes may be overshadowed by this error.'
Race Director Martin Harrigan comments: 'We are a team of runners ourselves so we fully understand the impact of this news. We are really upset that this mistake has happened and we take full responsibility for this situation. We remain committed to making the 2018 Brighton Half Marathon a great event.'
