What have I done?

It all started with lunch after the Carolina Beach 1/2 Marathon.  Delisa and Jill were telling us about runs that they had done or wanted to do.  They mentioned Run Disney as a fun race with really nice medals.  On that day the seed was planted. 
After my runners high subsided a bit and I had successfully gotten my team to commit to running the Flying Pirate 1/2 marathon I set my sights on Disneyworld. 
From what I gathered Disney races sell out at records pace.  I also learned that you could pay to run more than one race during the same weekend.  They called these little adventures a "challenge" And that all of the races are very expensive. The next race to go on sale was the Disney Wine and Dine.  I checked the day the tickets went on sale. It was sold out.   No problem,  I got on the email list so that race notifications would be sent via e-mail.   I set Disney on the back burner.   A few weeks later, I get an alert that Run Disney was having a Marathon weekend January 2016.  I would like to state firmly that I do not like marathons.   I know because I have run two.  After the second one I swore them off and decided that the 1/2 marathon distance was my distance of choice and that I would never be interested in running 26.2 miles EVER again. 
The day that registration for the Disney Marathon opened I was home from work for some reason.  I got a message from Delisa that the run Disney site had "crashed".  Up until that point I wasn't even thinking about this race or anything Disney for that matter.  But, I went downstairs and grabbed my laptop to look at the site.  After all, I'd never seen a crashed site before and was interested in what it might look like. 
The site looked ok to me.  I pointed and clicked and noticed an increase in my pulse rate.  What was happening?  The next few minutes were a blurr but the next thing I know I had registered for the Goofy Challenge.   That's a 1/2 marathon on Saturday and a Full Marathon on Sunday. Hu????  What????   WHAT HAVE I DONE???
