Being new to this forum, I can't tell you how much it has helped me. At 51 years old, 6'3" and 385 pounds I was fooling myself thinking that I was in some kind of shape. Going to the Doctor because I was feeling bad, I found out that I had type 2 diabetes. I started riding an old hybrid bike that I had bought 10 years ago. My first ride was 5 miles and I almost died, couldn't walk for 2 days. What a wake up call that was. 3 mounths later and 35 pounds lighter, I'm putting in 140 miles a week on that old bike. I average 15-16 mph for 20-30 mile rides with short brusts of speed up to 24 mph for 2-3 miles during the ride. My sugar levels are down in the normal range at this time. The old hybrid started breaking spokes, so I made a big jump and ordered a Specialized Tricross Expert Double with Velocity Deep V wheels. I still want to lose another 125 pounds and can't wait to get on my new bike next week. Living in South Florida really helps me to be able to ride year round.
Again, I would like to thank everyone that post on this forum, Your sharing of information has been very valuable to me and I hope to be able to do the same for others one day.
