I'm very impressed. That's a lot of miles to peddle.
I retired in 2008 and just recently have started peddling for exercise and to keep myself in shape. My bicycle is a recumbent, stationary bicycle, a Schwinn.
I prefer the stationary to a traditional bicycle for two reasons. One, our climate has about 5 1/2 months of cold, snow and ice and two, I have metal book stand that allows me to read while cycling. Something I couldn't and wouldn't do on a traditional bicycle.
However I am considering getting another traditional bicycle for the summer months. In the past decade many bicycle paths have been built around my area and it would be nice to take advantage . But in this case, no readin' just ridin'.
