I disagree. I never injected anything, but I was a distance cyclist for many years, ending almost 20 years ago and my legs are still mannish. High reps, low weight can build build muscle on a high-carb diet. What I really don't understand is why cyclists get bulky and runners don't.

Have you seen the thighs on sprinters? Maybe an extreme example, but they are often similar to cyclists.

Distance running and sprinting lends itself to completely different physiques.

Just like the dudes competing on the Tour don’t look anything like the guys competing in the velodrome.
