I gave up cycling in my early 30’s after spending most of the previous 10 years racing in the summer and training in the winter to the point where I think I just got burned out/bored with cycling. As I lost my fitness it got harder to motivate myself to ride everyday and next thing I knew, it had been 2 years before I’d got my leg over, as it were.
I started again about 5 years ago but now just enjoy being on my bike, I don’t care if I’m slow or fast, I don’t watch my diet, monitor my heart rate or care if some 12 year old on a Raleigh Grifter overtakes me up a hill. I couldn’t give a toss about whether steel, aluminium or kryptonite is the best frame material, whether I look a **** in lycra and I can’t even remember the significance of head angles, seat angles or top tube length
I got back into to it again because once I’d let all that other stuff go I remembered what it was I enjoyed the most about cycling. It gets me outdoors, enjoying the scenery and, when I’m going downhill, it feels like flying.
Best of luck with whatever you decide to do.
