I'd say MANY women here have managed it and many more are in the midst of that journey. I starting biking in March 2006 and lost 20 lbs over a year - 5 more to go. The changes that my body has gone through are amazing. People comment all the time how fit I am now. (me? me? If you knew me for the last 20 years, you'd know how funny that is.) Not only did I lose weight and feel stronger, but I am much healthier. I hardly ever get sick any more. And I feel great about myself.

For me, it helped me to find TE and learn from all these amazing women who are so knowledgeable and supportive. It also helped me to sign up at bikejournal and log every ride. Data made a difference for me, but it's not for everyone I know. I find motivation in watching myself improve in speed and distance etc. I also joined sparkpeople where I got info and support in the eating end of things. Logging my meals from time to time helped to keep me on track.

I say you find as many sources of inspiration you can and use them! And get out on your bike and ride, even if it's in old shorts and a t-shirt!

Good luck!
