Hello, I've been road cycling for about two months now, and I've seen improvements in my overall performance. However, my quads usually are quite tired after riding--not every day, but enough.

It seems to me that they shouldn't be so sore anymore. I asked my boyfriend about it, and he said that, observing me recently, my cadence is too slow. In fact, he said it seems to have gotten slower since I started using clipless pedals about two weeks ago (I disagree).

I don't know what my cadence is, but from using bikes at the gym, I'd guess average around 70-80? I know it's not as fast as my experienced cycling friends.

I feel like if I speed up my cadence, I'm going to lose speed (which I've been working on increasing). But I'm also getting tired of my tired quads! How do you find the balance?
