Hi there and welcome! And I bet it must feel fantastic to be back on your bike again! My boyfriend and I are both avid cyclists.. I am very new to the sport, have only been riding with any seriousness at all, for the last 2 years. He has been riding his entire adult life (he turns 40 next week), and most of his childhood.. He raced, racked on the miles like you. Then he wound up married, had a daughter etc and wasn't able to ride as much. He then broke his foot last year, which hasn't helped. He is back to riding again, but finds himself frustrated with no weightloss. His problem is portion control, and too many fats in his diet. He just loves food! I was able to drop my weight, thanks to the bike, but I also was able to be quite strict with myself. Now that I am just maintaining, I'm not nearly as strict, especially since I am able to ride nearlly every day each week.
Sorry to ramble.. just had to say hi from Nevada!
