There are lots of WISHers doing the 5K and usually added on to either doing the Half, Full or Goofy.
I am doing it because it is the one length of a race my Mom and her friend will do, so I do it with them. The next day I will be doing the Half!
Good luck out there and look for the WISHers in the lime green/yellow shirts!!
5K here too. I missed registration for the 1/2. It was already full when I decided I would brave it out. Oh well. Extra time to train for the Princess...
