I don't plan to quit riding until I can't remember where I parked my bike! I am 81 and my wife is close to 70. My wife and I have completed 23,118 miles of bike touring (total of 2 years) in 11 countries during the last 15 years. Then there are all the fun rides: training, recreation, and errands which come close to another 22,000 miles. Last summer we did a 1,050-mile bike tour in eastern Canada. We were 500 miles short of our goal, but it was not because of our ages. We may go back and complete our ride across Canada by finishing those last 500 miles.
We are in the planning process for a 2-month tour next summer. We are also planning our 12th annual bike tour with our daughters
I know it sounds a lot like bragging (well, maybe it is) , but I want to show what can be done with a little luck, and not talking yourself into "getting old".
