Makes Running Fun
Since I moved from Texas, I have struggled with finding a workout ‘family’. I am the type of person who needs the motivation to keep moving, provide accountability, and make running fun. Mandy has created a great network of people who come from all backgrounds, athletic differences, and has a plan for every body.
