I ran it in road shoes as it was bone dry, but I went over on my ankle inside the first mile as you hurtle down into the woods I sat there as the whole feild went past and was about to walk back to the start but instead ran from the back of the field.... so whatever you wear when its bone dry but a bit knarly, tree stumps and the like, lot of it is through woodland, and I only seem to recall one drawn out ascent, then a couple little uphills toward the finish
