Bought a new bike for fittness, and to drop pounds like many here. Bought a cyclecross / roadbike which due to my weight I probally should have waited on, but I like it, and I couldn't help myself! Reading alot lately, I have been bypassing the threads on climbing, as I live in Florida. What I didn't realizes is the neighborhood is not very flat, and I seem to live on top of a small hill! I had scoped out a route about .75 of a mile starting and ending at my home. The traffic is low, and it starts at my driveway. The issue is I can only make it around the loop once per day. :-( Here's the deal, After about 3 strokes of the crank, i'm in coast mode! Thats right , The first 1/4 mile I coast at a hight rate of speed(30MPH?) That part is fun! However in a span of 30 feet I have to shift down from the tallest gear to the lowest ( a 27 gear difference!) then begin the long 1/2 mile climb back to the house. By the time I get there, the legs are burning, and I'm very very short of breath. I barely make it back. So far this is not fun! I'm in Florida and my entire ride consist of a climb? This is no way for a heavy guy to get into biking!
