Riley (a Corona, CA native), is a 16 year old girl who was born with a bicuspid aortic valve which has led to an aortic aneurysm currently.  She is a very fun, intelligent young lady who leads a very normal life with only physical activity restrictions, but will one day soon require open heart surgery.  Riley will be cheering you all on and giving you your Medal when you cross the Finish Line!

This race was put together by her friends and family to raise money for the John Ritter Foundation in hopes of continued research for treatment and awareness.
