I ran (and by "ran" I mean walk/jogged) princess this year after nursing an IT band injury for three months during which I ran a total of about 20 miles (plenty of swimming, bike, and strength to pick up the slack). It was fine, with absolutely zero expectations, running with a friend who was a few weeks recovered from knee surgery, about an hour slower than my PR. I know that if you do start, you've got the self-awareness to know exactly what your body can take. And if you don't start, you'll have made the right choice for you, and we'll see you in January.
