Thought you might enjoy the race course profile summary for the run and bike legs in the duathlon;http://www.edinburghduathlon2010.com/uploads/Course%20Maps_Competitor%20Versions_Approved.pdf 

Apparently there is over 2000 feet of climbing for the 41K bike course and there is a steep technical descent which could stir things up a bit for less experienced riders.  Also the run has a steep hill that we run up and down a few times.  Therefore, I need to tailor my training a bit over the next few weeks to include more rolling courses both for the bike and run.
