She's a Brick...

"...house. The lady's stacked and that's a fact,ain't holding nothing back."

Ok ladies, the first brick (bike/run combo) is Thursday evening (5/6). There are a number of theories behind the "brick" terminology:
*your legs feel like bricks trying to run right out of the saddle
*you are combining/stacking two events on top of each other
*the thought of doing a triathlon requires climbing a mental brick wall?

Tell me your thoughts on the brick? All and all, we're just another...
