Gulp!!!

I've entered the Rhayader Round the Lakes 20 mile race, I did the 10 miler in October in the pouring rain in the same area and so I thought this would be a beautiful pre marathon run. I have since looked at the route map which can be viewed at http://www.mapmyrun.com/run/united-kingdom/rhayader/317202262. Thank you very much Steve for bringing this to my attention as I am now going to have sleepless nights anticipating the monster of a hill. I guess if I can can get through this then the marathon will be a breeze!!!
