That race is in Texas, just south of Midand/Odessa Tx. I don't know how long that race is, but just down the road a bit (Ft.Stockton,Tx) is where the big one is, Big Bend Open Road Race. I ran it in 2007, what a RUSH!!
BBORR is a 120 mile event. 60 miles each way with 59 turns on HWY 285 that runs from Ft.Stockton to Sanderson Tx.(Davis Mountain Range) Has everything from 5 mile long flat straights ,sweepers,blind truns out of a quick rise (hill) with elevation changes of about 800 feet through out the run. Absolutely a beautiful drive. Its a must do IMO .
ps. a good navigator is a MUST
