Don't get discouraged. You'll have totally awesome days. You'll have totally sucky days. You'll have plenty of days where you look out the window and say "F that".
You know what your goal is. It will be far easier to achieve your goal if you train more. I can give you a first hand example of this. I spent the end of November and first portion of December in the ICU. Not only did it land at a horrid time in my training schedule, but it depleted most of my endurance, lung capacity and muscle tone. On my pre-Christmas cruise, I went on the Disney Dream and did the 5K on
Castaway Cay and saw just how bad I was. Worse than before I started training for my first event. I had a decision to make. And what my goal truly was.
Choice #1: Throw in the towel and skip the three event I signed up for over Marathon weekend (thereby losing the registration fees) and cheer on other racers--all the while be longing to be on the course.
Choice #2: Still participate mostly as a walker and probably have some pretty horrid finish times.
I went with choice #2. And although my times were significantly and embarrassingly bad, I used the opportunity to smell the proverbial roses. I cheered on my fellow participants more. I took more photos. I listened to what my body was telling me and when I needed to slow it down and when it allowed me to pick up the pace. I am glad I went with choice #2. My goal was to have a good time and bring home the bling. My goal will probably never be to get a personal record time at a runDisney event, there are too many distractions.
I expect my Tinkerbell time to be improved, but I'm not sure by how much, as I only have two weeks and don't want to injure myself.
