Twenty of them!! You must've been throwing up at the end, nice workout though!
Hey this is Tim remember? He'd only throw up if he's NOT running.
We weren't pushing them too hard, so 20 wasn't too bad. We actually did a session with 50- 200m and 20sec rest last year :P (though those were a little slower)http://www.attackpoint.org/viewlog.jsp/user_10490/...
I did that once in high school......... no idea why
Totally thought that you meant that you had run either 20meters or 200meters haha xD
