Tomorrow, I turn 55. In observation, I’ve decided that my year in fitness should revolve around the number 55. Since I dabble in running, I’ve decided one of my goals will be to run 11 5Ks, the logic being: 11 races x 5K = 55(K). But which 11 5Ks to do? It was a decision that became more difficult as I looked around and discovered just how many 5Ks there are.
