WPSD is working with Atlas Physical Therapy and Paducah Athletic Club to help 10 local runners prepare for a half marathon. Our Go the Distance runners are training for the Murray Half Marathon and the Paducah Iron Mom. We’re asking the runners about what inspires them and why they’ve decided to take this journey. Karissa Shelton is a busy mom of two. She’s a volunteer firefighter working to get Candidate Physical Abilities Test, or CPAT, certification. Shelton is running about 4 miles a day. When she started, she found running 1 mile to be a major struggle.
