I simply go out and ride as fast as I can while enjoying riding unfamiliar terrain. Don't worry about points. Just come on out and ride. Hopefully that answers your question.
Nate: Didn't you ride last year's Gator Bait??? If not, shame on you.
There will be a morning loop and afternoon loop, both around 30 or so miles. Can't tell you if there will be a fuel stop yet. Nate you a ride a KTM right? You'll be plenty fine without one.
