The Grand Canyon’s rim-to-rim trail is not an ordinary day hike: a marathon in distance, a mile change in elevation, through a desert that swings through extremes of heat and cold. Rim-to-rim hikers put their bodies through a grueling experience. That makes them the perfect candidates for a study aimed at predicting medical emergencies before they start. KNAU’s Melissa Sevigny reports. 


She would have been the youngest person to have hiked the entire length of the Grand Canyon - about a thousand miles off trail. Ioana Hociota, 24, was close to her goal when she stepped on the wrong rock and died in a hiking accident.
