I ran the R&R Chicago Half Marathon in 2012 and 2013. This was my first race and I truly had no idea what to expect. I can still remember how nervous I was waiting at the start line. It turned out to be an experience I will never forget. There was many times that I did not know if I was going to be able to finish, but with the support of the crowd(and my boyfriend) I made it to the finish line. The running experience was so great that I ran it again in 2013. Please note that the food and drinks after the race are great, definitely the best I've had. Xsport also has a complementary stretching tent that I'd take advantage of and use. :-) Happy Running!
