I had a look at this on the website. The organisers are to be congratulated on starting a new event. I know the area from other races there and it looks like the marathon is two out and back runs on the same route, from one side of the Mendips to the other. Tough, scenic, but also a bit uninspiring as you will be covering the same bit of ground 4 times. Perhaps I am being unfair, but with a few more marshalls and a circle route rather than a line, they could have made a really attractive race.
