Good to know I'm not in the minority lifting heavier weights. I would though, like to improve my lactic threshold, but I guess that'll come from time on the bike.
I would also add that the benefits of lifting weights are many, especially as you age, as helps you maintain muscle mass, but also bone density. Cycling, unlike running, is a non-impact activity. So while doing a 100-mile training ride might be great for your cardio-vascular system, it does little for your musculo-skeletal system. Take note, those of you who are over 50 and are proudly eschewing lifting weights. You're not doing your future self any favours.
Good someone pointed this out. It's not just for older folks either.
