Bike adaptation

Whoohoo, my new bike is here! I decided to get a tri bike since I've been doing triathlons for three years on my road bike and I’m going to be doing IMLP next year. I wanted to do it right, so I went up to Fitwerx in VT, and had them fit me. This weekend, I went and picked up my new black Guru Cron`Alu. I’m thinking of naming it Gerald… an obscure reference to a Pink Floyd tune (Extra points for naming the song)

In any case, being excited about the bike, I go for a spin on Tuesday evening. Hmm… going from a roadbike setup to spending an hour in the aero position is different. So, anyone have thoughts on how quick the adaptation will be, any exercises to do off the bike to help. My riding time is a bit limited at the moment, I’m training for the Hartford ½ marathon in a few weeks. For the record, it’s mostly my next that is sore, although the forearms aren’t feeling great either.
