I entered my first 5k about a month after I started running, so I was in NO WAY prepared! LOL But it was a walk/run, so I decided to give it a shot. My 18-year-old daughter joined me (it was her first, too). She finished her first 5k in 27 minutes! This was over 2 months after basketball season was over and she hadn't done squat since, but there were a lot of kids her age in the 5k, and she wasn't about to let them all pass her.
Anyway, about 1 mile in, my hip decided, all of a sudden, that it did NOT want me to run anymore. Well, crud. I still had over 2 miles to go, and wasn't doing too hot in the first place. So I wound up walking almost all the rest of the way. There were some that stopped after the first lap and didn't finish at all, and coming around to the finish there were still two people behind me. But they must not have crossed the line, because when the official times were posted I was DEAD LAST on the clock!
It was great fun anyway, and I wouldn't change it for anything.
