I think it's safe to say you're not a "complete novice again"! You may feel weak, physically, but if you've ridden professionally, you're spades ahead of most people.

Good for you for getting back into it. I spent the last couple of months barely riding, because of sickness. Just started getting back into it and today rode my hardest and longest ride since I got sick, 31 miles with the club. I did pretty darn well under the circumstances and it felt so good to be out there and riding respectably. While I have a ways to go to be in the shape I was a few months ago, I was highly encouraged. It will come back for you (even though it's been a big longer than two months for you!). But I'm sure you'll be passing up the rest of us in no time.

Welcome to the board!
