Back in my early days as a tricycle rider, a century ride was admittedly beyond my imagination. As I rode more and more, a 100-mile day no longer seemed so impossible. After I had been pedaling the trike for about two years, I decided to work up to a century. And I did it!
As I worked to adjust to two wheels, the century bug bit again. First with the hybrid; and later, with the road bike.
Having put four solo century rides under my belt, I decided that my impossible cycling dreams were 1) a double century, and 2) a 5-hour century.
I've always figured that I have a better chance of succeeding at the former. Riding double-digits in five hours (including stops) would mean having to average over 20 mph. I can reach 20-21 mph, but can't sustain it for long at all -- yet.
And finally, my ultimate impossible cycling dream: successful completion of Paris-Brest-Paris!
