NVA, organisers of next month's Speed of Light event on Arthur's Seat in Edinburgh, are inviting experienced runners to take part for free. To qualify you'll need to be able to show a turn of speed, with a sub-4.30 marathon or sub-2 hour half marathon time, and must be available to run on one or several nights from 8 August - 1 September.
The event is billed as 'a remarkable fusion of public art and sporting endeavour' and sees participants run a choreographed 90-minute route around Arthur's Seat at night in specially commissioned light suits, with the display viewed by a ticketed audience as part of the Edinburgh International Festival and London 2012 Festival. A trailer for the event can be viewed on YouTube.
Organisers recommend that participants spend up to 20 per cent of their weekly runs practising on hills or steps, in preparation for the event, and suggest that you practise night-time running by donning a head torch and getting out on a hill to get used to show conditions.
Adrian Stott of Run and Become said: "Ever since Angus Farquhar came and chatted to me about Speed of Light two years ago, I was fascinated by the whole project. The idea of hundreds of people running slowly around a hillside wearing light suits that create stunning visual imagery seemed at once ludicrous and inspirational. The idea has slowly grown into a reality that will be a profound experience, whilst also being seriously fun for all those who take part. If you haven't already signed up, and are of reasonable current running fitness, I would encourage you to take one of the remaining late places. Like the Olympics themselves, opportunities like these things don't come around too often."
