I did my first intervals on the bike. There was some logistic issues (how to ride hard and keep your eye on the clock...and what _was_ my beginning time?) but all in all, I made it. Spokewrench I started with an article on intervals by Selene Yaeger and she recommended 5 intervals of 5 minutes with a max of 3 minutes rest between. I'd say I was pretty done after 3 but I have a rule that I don't keep doing it if it will make me never want to to do it again. and so my last two intervals were not spectacular.

I first did intervals in spinning class but the road put a level of authenticity into things that cannot be replicated in the spinning studio.

I probably will not follow Yaeger's article too compulsively. I don't think I would like such a steady diet of intervals through the week but I really liked seeing that I actually was pushing my speed.

Here's the article if anyone is interested. http://www.bicycling.com/training-nu...-fat-intervals
