I just registered for the 2015 Bank of America Shamrock Shuffle 8k.
What have I done?
I missed what was supposed to be my last race of 2014 due to illness, so I went looking for another 8k to sign up for in the new year. I've heard about the Shamrock Shuffle every year that I've lived in Chicago, and I've known people who run it every year and love it.
But...yeah...it draws 40,000 runners. That's a lot of people in one place.
This may turn out to be a great experience, or it may be a huge mistake. Only time will tell.
