So sayeth the Oxford Desk Dictionary and Thesaurus (American Edition). They conveniently left out the triathlon (or at least Team in Training triathlon) definition.
Brick /brik/ n. 1 A workout comprised of two of the sports making up triathlon, specifically cycling and running.
The brick workout is interesting. It's essentially a way to let you feel what it's like to hop off your bike after a ride (minimum, race distance) and start running. Sounds simple. It isn't. Try it, but don't ask me for a band-aid if you fall and break something. The first time you try it, it's a little like having a couple of shots of tequila, closing your eyes and shaking your head really hard, then trying to walk on a balance beam. Your legs won't do what you tell them to. This is because they know you are insane. You should stop. Sit down. Have a stretch, maybe a pretzel. Not go charging off to run a couple of miles.
Even so, when you're done, it feels kind of good.
