tired

I'm tired.  3 straight mornings of running. 19 miles.  Only 31 to go for my 50 mile week.  Lighthouse 50k this Saturday in Blanco.  I'm pretty excited about getting in a 50k.  But I'm a bit nervous about it too.  I've been getting in some decent mileage but my longest run is only 18 miles and that was several weeks ago.  That run was pretty hilly and I've got plenty of other hilly miles where I think I'll be alright.  The course is a mystery too, so that's kind of fun.
