My memory from last year is of bloody great hills, rain, puddles, cold and more rain. And lots of mud in the car park making exiting the field interesting. It is great that there is the school for you to change in, makes hanging about so much easier when you can do it in the warm. I have not entered yet but am pretty sure I will do so.
If this works, there should be a link to a map with an elevation (click on the button next to “map”).
