4 Days Till Marathon

Now I'm thinking about it, obsessing about it, worrying about it.

What to pack. What to put in special needs bag. I should have a spare pair of shoes - I only have one pair worthy of a marathon, the others have too many miles on them. It might rain. It might be hot. It might be humid. It's going to be dark at the beginning. How will I change out my lenses in my glasses if it gets sunny. Where does Dude need to be to change out my fuel belt bottles. What if he's not there when I need him. I should have bought an IPOD shuffle, my nano only lasts 3 hours. Should I still wear it and just not turn it on until the 2 hour mark? My nutrition has worked in training, will it work through the final 6.2 miles? What should I eat for breakfast? When should I eat breakfast? What if I get a blister? I've never had a blister. Should I pack some tissues in case there's no toilet paper in the porta-potties? Should I wear my long sleeve shirt under my other shirt? I hate being hot. How bad am I going to smell when I'm done?

Do I mentally have the strength to do this? Am I ready?

What if I finish and feel good - does that mean I didn't push myself? What if I finish and feel horrible - what's that going to do to my Ironman mindset?

What if I don't finish?
