Did this one in 2009 and have entered again. Looking at my Garmin data there is a reasonable hill around 4 miles and a total bitch of a hill at the 10 mile mark. Most powerwalk up it and don't lose too much time. Last 2 miles are pretty quick. Very scenic course though. I'll be carrying more drink than usual due to problems at previous events organised by these particular organisers but hope it's not needed.
