Thanks everyone for all the positive feedback and advice. I have been on Weight Watchers for 1 1/2 yrs and have dropped 50# and want to lose another 20#(I had a little set back Dec 2010 when I broke my ankle in 3 places, so after surgery of plates/screws). I joined a local cycling club and see that there are some slower rides planned. Since I ride by myself(I can't seem to find any riding partners - none of my co-workers ride). I guess I want to make sure I'm heading in the right direction with training to get faster and become fitter. I appreciate all of your input.
