Tell us about your training.
I didn't have the time for a full cycle, so trained for 5 weeks. I did an 18 and 20 miler three and two weeks, respectively, before the race, and in each case, ran half of the long run on a treadmill "on blocks", so that it was decline. This is very necessary in my opinion (very long sustained downhill training)...the course is obviously set up to be fast, so if you get in the downhill runs, you can get away with an abbreviated cycle.
