One of my wife's good friends has MS. I did my first MS150 the first weekend in October. My training consisted of my commuting, 100-120 miles per week, plus brisk weekend rides with a group of buddies who have been doing the tour as a group for many years. Unfortunately, I missed 5 weeks of training during the important July-August period due to travel then missed 3 MORE weeks in September due to minor surgery resulting from an otherwise minor crash. I wound up back on the bike with ONE WEEK to go. Keeping up with my group wasn't even a remote possibility, but I did finish. It would have been a lot more comfortable with those 8 weeks of additional training. It was still a great experience. Very well organized with rest stations every 12-15 miles or so. Nice activities and entertainment though our group entertained ourselves by doing our own steaks, drinking beer and telling dirty jokes.

I could not have done another 25 miles either day, but then I missed a lot of training. With the additional training I'm sure I could have. I am looking forward to next year's tour. My "training" objective for the year is to keep up with the 30-somethings. I'm the old guy.
