REdoing it: The Couch-to-5K Running Plan

Arrrggghhh. I suck. Really, I do. I started out this year with "Yeah,I am gonna run a 5k on my 40th bday...I have a year to train, nuthin' to it..." but the reality is, I bit off more than I could chew in several areas. So...I still have 4 1/2 months to train. I think I can do it. It is a little over three miles. I think I can do it. I think I can I think I can I think I can...chugga chugga puff puff. I visited my fave website for this very training, it is www.coolrunning.com The Couch-to-5K Running plan or c25k for short. You train three days a week...walk, jog, walk, jog, walk, jog. Here is my teensy predicament. I am tired. So tired. The kind of tired that makes you wonder if someone slipped something illegal into your water bottle. Doc says low iron and possible anemia. I have been eating ice like I will never have the chance to eat it again. Killlin' my teeth! Here is the challenge: Will I use this as an excuse to not train? I can't! I will never turn 40 again and running on your 41st bday doesn't look as good on a tshirt or facebook post as running your first 5k on your 40th. So,I must get thy bootay to the gym and hit the treadmill. Walk, jog, walk, jog, walk, jog.
