It used to make me sad that by the time my kids were old enough to cycle up big mountains, I might be too old/unfit to join them... but the massive growth in the last few years of electric bikes (mountain and road) makes me really excited that I actually might be able to keep up. I don't know if e-bikes would help given your condition, but if you haven't tried one, it might be worth a shot - they're amazing
