Tired. So, so tired!

I'm tired. I'm tired of running. I'm tired of work. I'm tired of this cold weather. Spring break is coming up and with it, THE marathon. I'm getting a little bit nervous. What if I can't make it 26.2 miles? What sane person would even put herself through something like that? I think crossing that finish line will be so bittersweet. I will be so proud of Katie and I for finishing a marathon and I will be SO happy to be able to take a break from running. After crossing that finish line I just may sleep for 12 or 16 hours. I think I'm just THAT tired. I was thinking about it today. This week's mileage will total 49 miles. That is an INSANE amount of energy expended! Let's say that I average 10 minutes per mile. That's 490 minutes or 8 and a little bit hours of running. Or 5,032 calories burned. That's about 2 pounds of fat. JUST FROM RUNNING! That's CRAZY! It's been a great, crazy experience!
