Hi Everyone! I will be down in Disney this year for my first marathon, and I was wondering if anyone had any advice on changing my start corral at the Race Expo? I have been placed in Corral D, because originally I was told to start further back.. unfortunately, I'm beginning to realize that this is a bit TOO far back for my usual running pace, and I would like to be moved up to at least Corral C. I anticipate on finishing between 4 hr and 4:30. Possibly faster depending on how I feel raceday. I know that the rD website says I can bring proof-of-time to the Expo and have my corral changed... I was wondering if anyone had any tips for this? I'm mostly wondering how much of a hassle this change will be... Lots of time? Have to change numbers/write on my number... etc? Any advice would be greatly appreciated! I know I should have done this earlier, but was caught up with my training and fundraising (with TNT). Thank you! See all of you fellow runners soon!
