A bit of history: Didn’t start cycling until 44 years of age after a divorce. Mega unfit at the start but got into it over the next two years and got reasonably fit. Re-discovered women and stopped cycling apart from a mile or two back and forth to work each day which I did for 20 odd years as I couldn’t afford to run a car. I did do Lands end to John o Groats on a mountain bike back in 1997 as a holiday but that was it. Got sick of cycling to work each day, rain,sun,wind,snow etc and bought a car 4 years ago and the cycling went out of the window. 3 years ago I decided to try to get some fitness back again, built a couple of bikes and started training on a dumb wheel on trainer. Being Billy no-mates everything was done on my own and I never really went outside to ride. I trained for about a year using my own plans+ GCN videos but most have concentrated on endurance level 2 stuff with maybe some Hiit once a week. I joined a local cycling club last year at 68 years old went their club rides on Sundays. I can now go on their red rides (average 18mph over about 50 miles) hard but I keep up. I bought a smart trainer (March 2022) and I am looking forward to improving my fitness further so joined the SYSTM program at the same time as I bought the trainer.
