1/2 Marathon

Jeff and I are thinking of running a 1/2 marathon that will be on October 3rd. We know that some of you have done this before. What are some good tips? I will be recovered from my DNC in 2 weeks, so we will only have 10 weeks to train. Any ideas? By the way, if you would like to do it with us, you are more than welcome to join. If you register by August 1st, it is $15 cheaper (even though I think it is kind of ridiculous to have to pay to run anyway.) :)
