God I miss running. First cruise I brought my shoes but we were having such a great time as a family I skipped it. Second (and techically third cruise since it was B2B) I had broken my foot twice in the 7 months leading up to the cruise (dumb luck - same foot different bones). I have had two major abdominal surgeries this year and haven't run since last Dec. Chance of doing CC 5k in March - zero. Seems like a pretty good reason to book another cruise however.
