just finished my first half marathon...by myself...on my TM but that still counts right? hehe 2 hours,5 mins and 22 sec...good timing? WTH..Im just glad i did it!
I watched the movie "gone baby gone" and then I just got it in my head to do another 1.5 miles to say that I did it. I just listened to music for the last little while.
As for signing up for a HM, there aren't to many around here. Actually, I don't know if there are any! LOL HM would cost me a plane ticket...hotel room and sooo much more! hehe
I can relate: I trained all winter for one and then about 3 weeks before the race, the friend I was training with found out she was pregant and bowed out. So, I did the same thing you did and ran the distance, just to say I did it!
Personally, I think a Treadmill run is harder than a real race... the boredom factor is huge!!
