Yes

Well I got a chance to spend all afternoon from 2 PM until 7 PM riding my bicycle. I rode 50 miles, the bicycle worked fine after sitting about for 10 months, however the power source me was out of shape. What sould have taken me 3 hours to ride took 5 hours. What I thought was flat ground 10 months ago seemed like hills today, My legs felt like rubber after 10 miles but I said so what Elf keep riding you never know when this can happen again. It was much easier when I was riding 50 to 70 miles 6 to 7 days a week. Must try to find some way to stay in shape.
