Well I know how(practice and pushing yourself), but its crazy! I was riding today and I got a lift(draft) offered to me. Dude was averaging like 30mph. I stayed with him for about 2-3 miles then I just couldnt hang on anymore. I am working on getting my speed up but im wondering why I couldnt stay with him while i was drafting him? He has serious skills. LOL. When im doing intervals, I end up dropping off quickly. What am I doing wrong?
