Lazmo
Old and hopeless
Back when I was climbing ~25,000m each month on the road bike and looked vaguely anorexic, someone asked me why I needed to be that fit. I didn't have an answer. I think it's possible to be 'too fit' and I feel much healthier now that I'm getting my fitness from a couple of MTB rides each week (and commuting to work sometimes) and am back to a 'normal' weight. When I was doing all those ks I was getting sick all the time as well, which is a known thing as the immune system can be compromised when your body is working so hard all the time.
25,000 vertical metres a month... geez... sounds more like an endorphin addiction.
