Just wanted to update the thread. I am well on my way to goal, having lost 110 pounds since last May. I have upgraded my bike again, just a few weeks ago, to a 2014 Cannondale Quick 4. I am averaging close to 100 miles per week now. I try to get on the bike 5 days per week for an hour and a half to 2 hours, with the longer rides on the weekends. Having a blast and I feel terrific! Even better, I look a little better in my lycra after going down 7 sizes in clothing.
