That course is called the World Champion and the fastest time
is 41.14 by Patrick Goeres.
One or two athletes before you have had some troubles in the east end of the valley....
Not sure if I got all the contral locations exactly correct though so you can consider your time as unofficial.
Oh don't even count my time, I'll destroy it the next time I run it ;P
@Nev: And some have had trouble between east and west.
