Betty Fox, mother of Terry Fox, died this morning, one week before the anniversary of her son's passing.

According to her biography on the Terry Fox Foundation website, "it is estimated that Betty spoke to more than 400,000 school children alone during her 25 years of touring, leaving each and every child with the inspirational story of the Marathon of Hope."

We offer our condolences to the Fox family. To learn more about Betty Fox, visit TerryFox.org.
