Over 1,000 runners took part in a marathon and half marathon at the Eden Project today.

But they didn't have too much time to enjoy the scenery, it's regarded as one of the most gruelling events in the UK. It's now in its sixth year.

We started in 2009 and it was in partnership with St.Austell running club and they came and approached us and through another conversation we talked about having an event which started and finished at Eden,and we thought what better way to connect with the environment which is what we do all the time.

Around 300 runners took part in the full 26.2-mile race. The half marathon had a much bigger turnout. First across the line in the half marathon was Paul Whear from Cornwall Athletic Club. He wasn't fazed by the terrain.
