Also, it may be a combination of my poor endurance and love for simple trail loops, but my normal after-work crank session at DP usually runs:
First parking lot up Fire Road
Enter Yellow prior to second lot
Cut onto White at junction
Follow white all the way to lake, and continue back onto white to finish out on Blue
Head back towards lot 1, cutting into Yellow again at same entry point
Take new JORBA trail (on left) from Yellow all the way to lot 1
For most of you, the above is WAY too pedestrian I'm sure. But for a throwdown challenge, it's probably a sub 1 hour loop for the fast guys with almost no trail overlap.
Not like it matters anyway. Saw the 6MR time trial and had my jaw on the floor for a while. You're all crazy.
