Calorie Deficit

Yesterday the fam and I went scouting in town for acceptable running locations. The forecast for today was overcast with no precipitation, so I figured if we could find a road with clear shoulders I might have a shot at running my scheduled 7 miler outside. Unfortunately most of the roads in town still have pretty snowy shoulders. The roads out by my house seem to require a weather anomaly to be runnable this time of year. By the time we were headed home I was pretty sure that running outside was out of question. This morning I ate breakfast at about 8 am. Then at 9:50 am I had a banana. By about 10:45 am I was ready to run. My plan was to do the first 10 minutes the same way I did yesterday's run. Then alternate runs of 10 minutes at 5.0 mph and 10 minutes at 4.5 mph. By 17 minutes in I knew that my plan was for crap. While it is perfectly fine for me to get up to 5.0 mph on my shorter runs, it wasn't going to be feasible with such of long distance on the menu. The 4.5 mph felt a lot better. By 30 minutes in I had decided to up my speed to 4.6 mph and try to leave it there as long as possible. There were a few times that I had a crisis of faith as to whether I would honestly be able to finish. It was just getting to me that I had been running for over a half an hour and I still had at least an hour to go. In all of my preparations for someday running a half-marathon, I guess I haven't spent alot of time considering that I may be on my feet for 3 hours or more when the day comes. Luckily I was able to work through my mental freak out. One of the things I told myself was that the race won't be held on a treadmill, that seemed to make me feel better. Somewhere near an hour in I had a slight pain on the top of my left foot, the same place I was previously injured. I suppose a cautious person may have called it quits there, but I pressed on. I was relieved when it went away 3 or 4 minutes later. In a week if I'm laid up with an injury I guess I'll know where my error was. I didn't have any other problems until about the 6.4 mile mark. All of sudden I was hit with really intense hunger pains. Something I haven't really considered through any of my runs yet, is the possible need for gels or gu's. Clearly as my runs are getting into these longer distances, that's something I'm going to have to plan for. I finished running all 7 miles in 1:30:57. The most surprising number though was calories burned, 1189. It bears mentioning that is calculated without a height or weight input, so in reality it was probably a larger number. I can say without a doubt that this was my toughest run, but I think that is mainly because it wasn't outside.

Nice run! Definitely need to plan out nourishment once you get much past an hour.

Check out your planned half marathon to see if they have Gu or something like it on the course -- many do.
