Training for Cross Timbers Trail Marathon

Well, training is a little slow going actually. I've been putting in loads and loads of interval training sessions on the treadmill set on a pretty decent incline, but not too much running outside. I just can't get into a long run mentally when I spend the entire time freezing my ass off! I am such a flipping pansy when it comes to cold weather!! For all you guys that ran and actually finished Bandera this year in those conditions........MY HAT'S OFF TO YOU!! I mean, dude, it was freaking cold out there! Anyway, hopefully next weekend will be warmer and I can get in a good long run. I've realized that it really doesn't take much training to just finish a marathon so I should be good. I'm not looking to place or anything, just enjoy the trail since it's so amazing!
