Do you want to do it?
Then yes, you can.
When I first started riding I was told..."if you can do ___ miles comfortably, then you can do double that with effort"
Sounded like good advise to me. I had done 50 miles, once 3 months before a challenging century was put before me. So I thought, I did 50 (once) what's 100? And you know what....I did it! Not fast, but it was great! At mile 50 my friend asked how I was doing...my reply was..."great...every mile from now on is the farthest I've ever ridden!"
The moral is...if you beleive you can do it....then yes, you can. Your fitness level is there. You just have too beleive in yourself!
"The bicycle is just as good company as most husbands and, when it gets old and shabby, a woman can dispose of it and get a new one without shocking the entire community." -- Ann Strong, Minneapolis Tribune, 1895
