Bill, why not test that fitness and sign up to do Blood Sweat and Gears in Boone, NC. Me and Tina just did, she will do the 50 while I do the 100. I did the ride couple years ago and it is a great time. Not as hard as 6 Gap but the climb up Snake Mountain is one of the toughest. I did Mt Michell and it's a *****cat compared to Snake. BSG is probably one of the best supported rides I have ever done, police and fire man every intersection. The rest stops are on the fly, if you so choose, I stopped but you can just grap stuff like going through a feed zone. Going to try and break 6 hours this year did it in 6:07 the last time and I had never done a mountain ride before. Dan
