Sunday, March 17, is the day of the Shamrock Run, benefiting the Doernbecher Children's Hospital Foundation. We get details from spokeswoman Devon Downeysmith, then hear about one of the conditions that the proceeds will combat, Spinal Muscular Atrophy. We interview Cheryl, who will push her SMA-affected daughter Wren the entire route of the race, and from Alyssa Zavislak of Cure SMA.
