Am I a glutton for punishment??

After the 5K yesterday I found myself on active.com looking up 5K's and seeing that the Tinkerbell half still has spots open and thinking I wish I was doing the Pixie Dust challenge next year (10K on Saturday and half on Sunday)  Then I shake my head and tell myself to snap out of it! I remind myself how miserable I was during and after my half.   Why does it seem the endorphins from running hacks into the crazy part of our brain? I read somewhere to never make a promise when you're in a excellent mood. I think this is the only way most people sign up for a race. After a race is over you feel accomplished, happy and so glad it is done. Then you start thinking that wasn't so bad.

Today another runner at work that saw me at the Run a Muk, he has ran the Boston marathon w/ an 8 min pace O_O, asked me how my race was and what I am doing next.  This is someone who in my 9 years at my job he has hardly said two words to me but now we have something in common. He wanted to know if I was doing the River Run again this year, I told him no I will be on vacation but I loved that run last year.  As we talked I realized I have no plans for anything running wise.  BFF and I are going to do the Biggest Loser walk/run. She is going to do the Half and I am planning on the 5K.  They have a Walk Half Marathon option and they allow 5 hrs to complete the half marathon.  That is a 22 min pace and I can easily walk a 20 min pace.  I was just thinking I could so do that but then I have flash backs MILE 10 and how I don't know & still don't know how to fuel my body property. What am I thinking?!?!?! Am I a glutton for punishment?? I said NEVER AGAIN. Walking for 5 hrs keeping a good pace w/o breaks just sounds like forever.  The Tinkerbell took me 3:43 with a pace of 16:50. I am still baffled by the fact that yesterdays walked 5K was only 20 sec per mile slower and yet I walked it!!  How is that possible?

My next post is going to address my problem with my nutrition and diet and how I am falling into old habits that seem to go hand and hand with working out........over eating.
