Hi Aggie, I don't know if you have ever heard of Selene Yeager, but she's an amazing athlete and I have one of her books. She trains for mountain biking and shares a great deal of information. Here is a link to her blog. She's also the most real, down to earth, athlete I've ever read about.

Enjoy.
