I did my first 5K last year at the Minnie, and I started about this time training and had never run before. I tried running 3-4X/week, then started having really bad shin splints and didn't run at all for the month right before the race. I walked at least half the distance, and finished in 38:45. Since then I've done 2 more, and now I'm training with the WISH team for the half marathon in January '08!
Beth - I did the Minnie as an excuse to go to WDW too - everyone thought I was crazy for going all the way there just for a 5K! It made for a really long weekend too, since we drove down and crammed in all 4 parks in addition to the race on Saturday morning.
Good luck to everyone - come join us on the weekly training thread!
