I have a hybrid that I love to ride. I bought it for fun, to get active, and to lose weight. I had an idea in my head about eventually getting to a road bike when I got fit, but I learned that my weak core and big belly prevented me from getting one right off. So there I was, loving my new hobby and my new bike, lost a few lbs, feeling good. Then I take a little trip without my bike and, missing the feel of wind on my face, headed to a bike shop to rent a bike for a ride. Turns out this shop has a Felt F5 carbon road bike available for just a bit more than the hybrid...who could pass this up? HOLY CRAP. I could not believe how FAST and FUN this machine was. At 265 I am well into the clyde-range, but I felt like a friggin fighter jet zipping around the the curves on the trail...long gentle curves became a tight slalom course and I found myself playing a game in which I was trying to find the perfect race-line through the turns so I wouldn't have to slow down!
I know losing weight is still a major focus of my health goals...but now a principal motivator to keep working out is to whip my body into shape, and train it to eventually be able to handle a bike like the one I just tried. Never thought I would be a racer, but now that is my new goal.
