From their website:
11/13/2009 - REGISTRATION FOR THE 2010 BOSTON MARATHON HAS CLOSED. Registration for the 2010 Boston Marathon has closed. Registration began on September 9, and the Boston Athletic Association is unable to accept additional entries.
I decided to take advantage of my BQ from last year (Baystate Marathon) and run Boston one more time. It's always bugged me that I had such a bad experience in my one and only Boston back in 2003. Good news is it won't take much to top it. Yes, it sucked that bad.
So Boston 2010 here I come! Thankfully I registered just in time.
