I just wanted to echo the comments that have been made about the mud pit in this year's race--you can throw your time out the window because it probably took me at least 10-15 minutes between the wait to get into the pit and amount of time it took to trudge through it.  Literally multiple times I couldn't move my arms or legs at all...someone mentioned that it was borderline dangerous and I agree.  I could tell some people were kind of freaking out because there was a sense that you might not be able to make it out.  It felt like what I would imagine quicksand would be like.  That, and the insanely long, poorly marked lines to pick up the packets were my only complaints, though.  They changed the obstacles up quite a bit from last year, which was nice.  It would have been nice to have more water stations on the course, also.
