If I was the producer, I'd just have them run a mile or two up a grueling mountain trail to where each team has to, grab a clue out of the box and then jump into an SUV and speed off.
Make it a real ordeal, too - something straight out of an army basic training course where there are obstacles to overcome, swollen rivers of mud to ford and every last inch of it on a coronary-inducing steep incline.
Pretty much try to put everyone of them into the hospital.
Then here's the best part...
Supply one less SUV than there are teams and supply special instructions for the last team who doesn't get a car.
In the clue, tell the last team that there's a penalty for displaying such incompetence before the first commercial break. Tell them that they have to return to the bottom of the course completing all of the obstacles and hazards in reverse.
When they complete the heartbreaking journey back down the hill after undergoing not only physical torture but also the emotional anquish of wondering what awaits them, they find...
Phil standing at the mat and all of the other teams standing proudly beside their SUV's.
Loser A and Loser B, you are the last team to arrive. I'm pleased to tell you that you have both been eliminated from...
The Amazingly Evil Race
*Phil laughs maniacally*
Cue the new sinister opening credit sequence.
