Everyone has FABULOUS advice & I "second" it all. Something i'd add is that u are out there in the corral EARLY & to stay warm we brought cheap small fleece blankets from Walmart (like $2) & gloves ($1). It's far more cozy than a garbage bag & u can leave off to side when you start-or gloves along the way; they collect & donate. YOU'LL have plenty of time-so get all those special photos taken. Bring $ for the expo on Fri/Sat-good stuff there! Don't feel weird wearing some kind of costume-it's very common (expo even has cute sparkly running skirts & wings etc, I bought green sparkly one from Team Sparkle last year). Remember it'll be dark(ish) a long time so somethibg that lights up is fun too-i wore my Tinker Bell pin from the main street carts. Smile at & hi-five those cheering u on! After, the post race is organized well & is quick & easy to use bag-check. Finally-I've found that if I keep moving that entire day/evening after-I'm not sore the next day. So put that Tinker Bell wing medal on with pride and head into Disneyland. It's the best feeling ever!!🏁✨ - TinkerSchelle  650.2 #164 8:10PM

Stop at the rare characters if you have time. Enjoy the time through the parks. You will be going backstage and last year at my first race I loved it! Take pics- I just use my phone. Get water and powerade at every stop. Run some, walk some, and sign up for runner trackin so that you know along the course what Disney has your pace registered at. - LilSterner  2656.0 #18 7:12PM

I run with a small belt that is just big enough to carry some salt tablets and gels, I always run the whole thing so you dont want a lot of water on you weighing you down, there are enough water stations where I dont think you will need to carry any with you. - diznymommy84  215.3 #1417 10:37AM

I'm walking it. I'm anxious, but excited. - JenAnneWho  300.7 #610 7:59PM
