Excellent! Started training on the bike this week, and been shocked just what a difference the hills make. Of course, as a runner you know that a hilly course will always be slower than a flat one but for me at least the penalty on uphills seems to be much greater when cycling. I guess that makes sense as you have to push the weight of the bike up the hill as well, but it's obvious that I need to do a lot more hill work in the next 2 months. If Box Hill really is a killer, I'll have to adjust my target time significantly so all feedback appreciated!
