BBC News Scotland
More than 2,500 runners from around the world have signed up to help light up Arthur's Seat in Edinburgh to celebrate the 2012 Olympic Games.
Every night for three weeks in August, hundreds of runners in special lightsuits will run across the extinct volcano to create a light display.
Runners will follow specially choreographed routes up the hill, which is situated in Holyrood Park.
Organisers of Speed of Light are calling for more runners to join.
