As a new to bicycling 65 yo. I am making progress. I have had my Trek 7300 for two weeks now. I ride on a short trail through a park 1.3 mi and do 4 or 5 trips around it every day. It is a bit rolling but nothing bad.
Today, I finally did 10 miles. Now compared to most of the people on here, 10 miles is nothing but a warm up. For me just starting it seamed to be a 1st hurdle to overcome. The best thing about it for me was the fact that I did it without going to the #1 ring. I stayed on #2 or 3 the whole time.
A little step but Progress never the less.
I still plan on riding my age by my birthday in September.
