My wife and I visited our son and GF in Yellow Springs, OH. We stayed in a motel in Springfield. There is a paved bike trail to Cincinnati, OH about 80 miles away.
Helga and I started on this trail with our tandem bike and met our son in Yellow Springs (about 6 miles).
So we looked at each other and said what to do. I suggested we bike to Loveland a little N of Cincinnati. My son was all for it because they have a great restaurant with some good looking service staff. Somehow we did not discuss the distance.
Well, I knew that this was going to be a long day and stopped in Xenia LBS and bought $40 supply of Hammer Gel and Cliff Bars.
My wife has never in her 66 years biked more than 75 miles in a day. This was going to be a first for her. The round trip was 125 miles and we did it at 17 MPH average. Our son kept up with us, sort of. One year ago he was a smoker since his teens.
We had big pasta dishes in Loveland and the Hammer gel and Cliff Bars were all gone. We were tired but no worse for wear and able to do other things the next day.
The message of this story? Age is no limitation. Food is out-most important. Ohio has fabulous paved trails. This trip was on the Little Miami Trail.
