So you’ve heard the term Sky Running but what actually is it? Well it’s an international series of running races held in the mountains, with most events having a VK or vertical kilometre – 1km of ascent in as short an amount of horizontal distance as possible, basically straight up! – a mountain marathon and ultra up to around 80km.

If these kind of events sound like your cup of tea, then you may be interested to hear that this year a UK based Sky Running series was launched, running alongside the existing international calendar of events.
