Is that a typo? MS250?
I know some guys ride the course all the way to Austin in one day, and repeat on Sunday.... is the 250 comment your own doing, a different ride, sanctioned? Do you over ride the first day, and then backtrack before starting the second day?

I don't see a problem with mileage and fixed... it's the hills in Bastrop. As for going around the park... I did that one year and vowed never again. The park is too much fun, and too pretty to skip. The alternate was the shoulder of us71. Not exactly smooth (rough asphalt I guess), and since it was a highway... the hills were LONG, and the wind from the cars was less than ideal.
