I was pretty strong when I was 50. I'd been directing a team of consultants instead of being one of them for a few years and traveling considerably less, so enjoying living where I live and riding year-round. Worked out every day and was road riding on the same composite Trek I'd ridden for 20 years. Cool girlfriend I'd been seeing for a few years. Worked hard played hard. I was a stud

I didn't start riding seriously until I was 28 but was active with all variety of skiing and white water and already had open rotator cuff surgery and a crushed L4 and major hamstring and therefore sciatic and other nerve pain issues, so I'd learned to live with a couple of things and doing well

My senior move at 50 was replacing a 13-21 7-speed cassette with a 13-23, running 53/39 cranks mind you, for my daily up my favorite mountain, which hits 20%. I'd gone up to 13-26 before I had to crash that bike at 53, but I was fit enough to survive being hit by a truck and thrown 20 feet

Bought a new road bike but that was a couple of years later when I could road ride again in 2015, same year Trek released the first Emonda. Love that bike (and the 11-28 11-speed with 50/34 cranks!)
