How NOT to train for a half marathon

So 2 weeks to my first half marathon. The training plan was well laid out but alas plans are guidelines are they not?? Last week no long run, decided to play a final fall tennis tournament, 2 weeks before foot injury no long runs, before that a summer ending sprint tri, all great stuff (except the injury) but not on focus for the event to cap off summer. Back at the long run today, 8 plus miles felt fine, one more long run next week back to 9 or 10 miles and I should be fine, but not ideal prep. Strange how I feel I need to make stuff more challenging, "hey anybody can do a half marathon if they do the work!" I still haven't really internalized and acted on the fact that it is ALL about the WORK! OK lesson learned and some pain to come in a couple of weeks but I will push hard and finish strong. Time will tell how successful I'll be!
