Schnitzle,
Guuurrrlllll you got the bug!! Woo hoo! I rode a mountain bike twenty some years ago when I was in college and then stopped riding. I asked my husband to buy me a bike last January for my birthday, only wanted something inexpensive as I didn't know if I would continue riding. Oh wow, I got the biking bug soon after! My starting weight was about the same as yours now, but have lost 25 lbs since last October. I have cleaned up my diet and have been riding consistently since the fall.

I rode that poor mtb to death almost! Realizing I like racking up the miles, I upgraded to my first road bike last month. It's been awesome! Now I'm training for my first century ride this summer (I posted a separate thread about the training, questions, etc....)!

It has been fun and challenging so far and I love adding a few extra miles to my long ride each week! Last Sunday I rode for almost 5 hours straight. I remember my first ride last year being 45 minutes and I was excited about that! So, enjoy each step you make, progress at your own pace and enjoy. We can't wait to see what you discover about yourself!

Have a blast!
