No rest for the not weary

Ahhh rest days.

Too bad you actually have to race or ride hard to earn them.

I need to carry a calculator or something for today's wicked workout. How in the world am I going to remember to do all of this when I can hardly remember to breath?

your rest on each interval will be half the interval length (2 minutes rest for the 3 minute intervals is fine). Each interval will be a progression in effort at every 30 seconds. You will start out in a controlled, but strong pace ... then you will punch up your effort every 30 seconds until the completion of the interval. Yes, at the end of each interval you should be hurting pretty bad, but not sprinting. You should be on a high effort of pain that you can barely last out for the duration of the interval.

Uhhh...huh?
Aw crap, I'll just go out and flog myself for random minutes, rest for 5, do it again. And call it a day.
