.....I am also so nervous when I think about how LONG it is. I want to do this race and feel good, feel like I can enjoy myself, chat with my best friend (also doing her first full) and enjoy the experience. I worry that if I aim for just running it, I will either hit the wall, or it will become such an overwhelming challenge and mind/body game at the end that I won't enjoy it as much or be able to enjoy WDW afterwards.
The cliche here is one step at a time. We both know that is BS unless nothing else is working. The easiest thing for me is to break the race into easy pieces. For example...
For me it's goes something like Start to Start - 4 mile Loop
Start to Over pass - 2 miles
Overpass to MK Main 4.5 miles
MK Exit to Turn onto Bear Island Road 2+ miles.
Start of Bear Island to AK (in park) 2.5 miles
AK Exit to World Drive 2.5 miles
Out and back 1 mile
Exit onto World (end of out and back) to DHS Custuming tunnel) 2 miles
DHS exit to BWV < 1 mile Tracked since it is clse to end and its the distance without a crowd. The Ecpot resorts provide lots of folks yelling.
Once in Epcot 1 mile to the Choir + three hills
Once at the choir a sprint
You will figure a way to break up the race that works for you. It could be pacing behind a certain shirt that drives you through a couple miles, talking with a friend (new found or old) or just zoning out.
As far as enjoying the race. Make yourself a deal. FIrst enjoy the training. After each run make a note of how you felt, what was good and what could improve. Also, if the training run was particularly tough, make a note of what you did to get through it. By far that is an important tool in the toolbox on race day. Race day will have a few stretches where you say I can't go further. Open that tool box and pull out you personal tools accumulated through training. Maybe it's singing, talking, staring at the person in front....find one of your tools and you will get through.
