Welcome to Bike Forums.

I started road riding when I was 65 years old, now 70.

Everything on my body HURT when I first rode.
I had to put foam pipe insulation on the handle bar grips, my hands hurt so much.

My first ride was 6 miles. Had to stop three times to rest.

Last Saturday I was able to ride 121 miles on a race bike.

Takes time but you will get in shape.
