any good cycling specific websites that have interval training programs?

no two coaches agree on the whole interval thing, other than the fact that if you want to go fast you will need a lot of that kind of pain. Better to get at least three or so training books.

Here is a link that will give you a start, on your quest for speed:thumbsup:

Some books that have helped me:

Arnie Baker HIT ebook - excellent resource
http://www.arniebakercycling.com/books/b_hit.htm
Maximum performance for cyclists - it'll kill you
http://www.amazon.com/Maximum-Performance-Cyclists-M-D-Michael/dp/193138262X

+1 on Arnie Baker's HIT book. It not only gives you the whole theory behind (in support of) intervals and intensity work but gives you a specific 13-week progressive program. I used it last winter starting around Feb 1 and it was the best training I've ever done.
