Bleeker Street Girl,
I just looked at your post with the before and after pictures. I had been wondering how I could look so much better than before and only have lost 10 lbs. I have only been riding for one year, so three might make even more difference. And for this thread - I am 57. Most of the people I ride with at my local bike club are in their early 60's, and I am now just starting to be able to keep up with them. On Saturday, I rode 49 miles! If you want to see a video clip of this ride, look at this UTube below. the ride is from north of Monterey to Pebble Beach Golf Course along 17 Mile Dr. in CA (where we had one day of sun between all this rain). My husband has started riding around with a camera in a rig that he made that rests on his chest - looks like suspenders.
