This month marked the 40th anniversary of the Marathon of Hope, Terry Fox's legendary cross-Canada run to raise money and awareness for cancer research. To mark the four-decade anniversary, Terry's younger brother Darrell has collected and edited 40 letters from 40 contributors (including Margaret Atwood, Bobby Orr, Tom Cockrane, Jann Arden, Perdita Felicien and Christine Sinclair) recounting the inspiration, dedication, and perseverance that Terry Fox embodied. Darrell joins Gormley to tell us about the new book "Forever Terry: A Legacy in Letters" (which supports the Terry Fox Foundation), and his brother's legacy.
