I just signed up for my 3rd half marathon. It is one week from tomorrow! I figured, since I am scheduled to run 15 miles that day I may as well run the half. If I can run the course in 1:47, then I will not run the additional 2 miles as per my training schedule. If I do run slower than a 1:47 finish time, then I will head back out on the course after cross the finish line to run the additional 2 miles.
Not sure if it was a good idea to run this, but what the hell. I've been having race withdrawals so this will satisfy me for the time being!
