First Half Marathon here too! I watched DH run the WDW Half in 2010 and it didn't even remotely cross my mind that I would EVER be able to do the same. Here I am 3 years later. And I'm even on track to beat his time!
I'm going to be a Debbie Downer here and say that I don't stop for characters. I've run two races: the WDW 5K in 2013 and the DLR 10K two weeks ago and the lines for characters in both races were wicked long. I'm not going to break my momentum for a character pic. Now I did for a pic of myself in front of the Castle but that's different.....I didn't have to wait in line for that one.
Think about your pace and whether or not you can afford to stop for photo-ops. There ARE stories out there about people getting swept while waiting for a character.![]()
I don't think it makes you Debbie Downer that you don't stop for characters. I don't think I'll stop and I didn't during ToT. I'll lose too much momentum waiting in lines and (is it safe to say this here?) I'm not a big character person

Happy training this week to everyone!
