Running Concrete Hero on July 14th to raise money for AIDS famlies

So one of the events I am doing, to stay healthy, and to help people out is competing in a Los Angeles event called Concrete Hero.  Its a 5 mile run with a lot of obstacle courses built in.  It should be a lot of fun.  I have pledged to raise at least $600, and I am currently at $495... Any help would be great!  I will keep people posted on the progress and updates as the dates get closer!
