As a reluctant runner, the very idea of jogging up a steep hill in the heart of the city of Edinburgh makes me feel exhausted. But add a few extra aspects to this challenge and suddenly I’m more than keen to participate. Arthur’s Seat, a formidable hill jutting out of the Scottish capital city, played host to Speed of Light – a mass choreographed performance of walkers and runners wearing a series of lights on their clothes, all in the summer darkness. It was curated by the Scottish arts charity NVA as part of the British Olympics celebrations and the Edinburgh International Festival.

Taking place throughout July, August and September, the project combined the natural environment, art and sport. Take a look at these photos – if they don’t get you running, nothing will:
