Give 100% of your marathon training and racing miles to a good cause and help fight cancer! Log your miles in Chicago’s Nike+ Marathon Charity Challenge. For this year’s Bank of America Chicago Marathon, Nike and Bank of America Chicago Marathon will be donating up to $100,000 in conjunction with the Lance Armstrong Foundation to support programs at Children’s Memorial Hospital and the Imerman Angels.

The number of dollars donated depends on the number of miles you run and log through Nike+! To reach our goal of donating $100,000 to charity, we’ll need to have 500,000 Nike+ miles logged between now and midnight on October 12th. Join forces with runners around the world as we prepare for the 2008 Bank of America Chicago Marathon and log miles for charity.
