~I had read something last year leading up to the Princess last year, to pay yourself a dollar for every mile you train, save it up for something special, and I did that!! I got myself tons of cute shirts at the expo
I absolutely LOVE this idea! I already have a special savings account set up called "Race/Registration", so on payday, I can tally up how many miles I've done and move the bucks over!
A few more things: find a local running store that will video tape you running to fit you for shoes. Shoes make all the difference! You don't want to give up because of pain or get an injury because of skimping on them.
Look up videos in
YouTube. Remembering will help you through the long runs. This may sound mean, but I would also look for people way more out of shape than I am so later I could think "hey, if that woman can do it, I have no excuse!"
Print the training calendar and put it on the wall somewhere you will see it. Put checks or happy faces or whatever when you finish a run. Some people get Disney stickers for this.
I also had the course map as my background. Then I can think "okay, I did 8 miles today, that gets me to the Polynesian!" I currently have the WDW Marathon course as my background.
Running Store - Fit2Run is a running store in FL that does this - it's how I learned that I over-pronate (my ankles roll when I run) and got a great pair of Brooks. They were very helpful and patient with me (a very overweight non-runner).
YouTube - YES! I think that is how I decided to jump into this. I saw someone's video and I was seeing all of these women older than me, larger than me, more out of shape than me and said to myself (I talk mean in my head) "If that fata$$ can do it, so can THIS fata$$!!!"
Training Calendar - I made a monthly calendar in Excel that tells me what I need to do that day, or which days are off days, and it is posted on my fridge, on my armoire (in sight of the treadmill), on my office cork board and integrated into monthly menu I make for home. I can't get away from my Training Calendar, and it's good motivation for me. Each month has a Disney Quote or Marathon Motivational Quote on it (May says "If it was easy, everyone would do it" and June says "The only way to achieve the impossible is to believe it is possible" from Alice in Wonderland). Also, I put it in a page protector so that I can use those dry erase markers to check off my days or make notes to myself. There is something so self-satisfying about checking or crossing off days with a big red marker!
I hung a copy of the race route on my armoire so that I can see how far I've gone. When I'm ready to give up, I can see that I'm so close to whatever and go just a bit further. I've only made it to the Toll Plaza, but I'm getting there!!!!
3. Don't forget throwaway clothes for the morning of the race. You'll need to get to your corral by 5AM at the latest, and you'll be waiting around for 45 minutes or so until the race starts.
...I'd also suggest not booking your room (assuming you're staying on property) through the WDW-IRUN number. I think there are better discounts out there if you look.
Keep an eye out for inexpensive hoodies/pullovers, gloves and winter gear around Christmas time. I remember last year on Black Friday, I got a Danskin quarter-zip fleece pullover for $4.
Walmart usually has skull caps or fleece ear warmers and those dorky magic gloves for a buck or so. If you are gonna toss 'em, you might as well not spend TOO much! (Granted, if we get a winter like we did a few races ago, where it was like 20 degrees, go ahead and get some REAL gear

)
Another option is perhaps booking your room to ensure that you get the hotel you want, and then shop around for a better deal. I've never booked with WDW-IRUN, but if it's the same as booking normally, you can book the Run rate and if a great deal comes out for your hotel, you can switch to the better deal. This way you have a room booked and don't have to worry about not getting what you want if you wait too long for a deal!
Thanks ladies for great tips. I wish I had more to add, but I've not yet run my Princess race, so I'm just here for tips and encouragement!
