TM San Diego 2013 Preview

I have been training pretty hard, in fact I have pretty much matched or topped my previous PRs in all my training.  I ran the 6+ mile Elfin' Forest in 55:26, which was a best be about a minute.  I will probably taper from here on in.
The course looks quite a bit different this time around, if anything it looks a bit easier and definitely a bit shorter.  About 10.4 miles.  There are quite a few new obstacles this year.  I am not even sure what many of them are, but I expect they are just terrain obstacles, like "hey run up this hill, no really it's an obstacle".
