We'll have to check with the mods to see if we can sticky it. I think it would be a cool idea to have FAQs for many of the Disney events.
It will take a little time to build it. Until then, check out the marathon FAQ for some great general run/walk, nutrition, equipment info. Also, www.disneyrunning.com/minniemarathon.html has a lot of great info with links to trip reports (with photos from last year). Just scroll down and you'll find info from those who did the 2006 race.
