What a great question. I love it! I have only run the marathon, and there are definitely parts of the course I love and parts I dislike. One of my favorites used to be the run into EPCOT early in the race when it was still dark and Spaceship Earth was all lit. Just so cool. But that's no longer a part of the course. I love the run down Main Street in the Magic Kingdom, of course, with the crowds lined up and cheering and the castle straight ahead. The challenge here is to control the urge to start running too fast (An 8-minute mile! What??). And, for some reason that I really cannot explain, I love running through Animal Kingdom. The scenery is just different; it feels like another spot on earth to me. Strange. On the flip side of the coin, they can bulldoze that ramp from World Drive to Buena Vista Drive right before you enter Hollywood Studios. In a ridiculous side story, while running up that ramp during my first marathon in 2007, they were offering up tongue depressors covered with a bio-freeze like product. I was ignorant and thought it was some sort of gel/food and nearly grabbed one and shoved it in my pie hole. Luckily, I realized at the last moment what the product was, but to this day the thought makes me ill. That ramp, though, sucks. They need to add another green Army man there, instead of just a medical tent for folks about to die. Also, with the exception of the baseball stadium, I have never cared much for the trek through ESPN. Too many turns - way too many turns - to make me happy. Plus, you're creeping up on mile 20, the infamous "wall," and it just seems to go on forever. Overall, however, I love the course. I love the support. I love the experience. I can't wait to run it again in January.
