I've now officially started working on the half marathon with the 5:1 intervals.

My mile time was slow (even for me). I was averaging in the 12's, and maybe one time did a high 11, during C25K. Last night was a mid 13! UGH. That's okay. Speed will come with training....right?
I ran with the new shoes, minus the special inserts. Overall much more comfortable, and the fatigue was much less, too!
On the other hand, my left knee was a bit soar afterwords and today - which I think had stopped with the inserts. Go figure. My main concern is that I don't want to go for comfort now, and end up causing an injury.
For the Disney Marathon Veterans - I'm a bit confused with how the 16 minute requirement is used. I understand (I think) the difference between clock time and chip time. I read that the clock time is used for sweeping people. If that's the case, then aren't us slow people starting out way behind? Do they go by "clock time" for when each corral is released or the first group? I know there's got to be something I'm not quite "getting" here.
Oh, and also within the corrals, if you're at the back of a corral, does it take several minutes to cross the start (again concerned about "clock time"). Does getting there plenty early help assure a spot in the front of a corral, or is the order specified for what part of the corral you're in?
Sorry for all the questions! My goal is to be far enough ahead that I'm not be pushed by the sweepers. But, I am curious how it all works!
Thanks!
