86 is the new 50. Great story and I am sure riding with the group brought back fond memories.
On our trip to France, we met a couple who were 70+, riding their tandem who were great cyclists. It was not so much about their fitness (they were in great shape) but their attitude toward riding and life. They were training hard leading up to the tour getting ready for Mount Ventoux. They had done their research on training for long climbs and were focused and committed. We met them early in the tour at the top of a climb and observing them climbing, they looked really fit on the bike with great spin while climbing. I expected them to be in the 50s. They did really well on Mount Ventoux which is brutally hard on a single but outrageous on a tandem. It is refreshing to meet people of similar age and older who have maturity but a total zest for life and a positive attitude.
