Half-Marathon Training

I follow the training regimens on running.about.com to train for races - I've run several 5k's and 10k's. This summer I am entered in the 2009 Rock 'n' Roll Chicago Half Marathon on August 2, 2009 as a charity runner for the American Cancer Society. To train for the race I'm using the Half-Marathon Advanced Beginner training program on running.about.com. I'm on week 9, currently - I repeat some weeks to pad out the time until the race. The long 10 mile+ runs are pretty brutal - I made the mistake last week trying to do a 10 mile run in the 90+ degree heat. I'll probably write more about this stuff later on.
