I did the MS 150 over the weekend. It was in Ohio. I was very happy with my speed (19.4 ave last 50 miles) and how I handled the heat. I am using the 405 garmin. Here was my last 50 miles of the last day of the ride. http://connect.garmin.com/activity/44669433
I am on a total vegan diet. I have dropped weight slowly ( 20lb), my total cholesterol is 103. I have type 1 diabetes and my last A1c was 6.4. I am very happy with the results. I don't want to have Bypass again.
