1. Synchronized driving: two athletes drive identical cars around identical race tracks at the same time while avoiding identically placed obstacles. The drivers are judged on how closely their laps match up. The degree of difficulty can be increased by selecting hard to control vehicles, including the Reliant Robin, a 1978 Buick LeSabre, or any Toyota manufactured in 2010.

2. Synchronized driving: two athletes hit one golf ball each down the same fairway from golf tees set 20 feet apart. Points are awarded for similar shot timing, ball trajectories, and the final position of each golf ball. The degree of difficulty can be increased if the golfers elect to be blindfolded, use a putter to strike the tee shot, or be paired with Jean Van Der Velde.
3. Synchronized deriving: two athletes simultaneously solve identical differential equations. A panel of international mathematicians awards points based on how quickly the two athletes arrive at the same solution. Additional points can be awarded if both athletes satisfy the Liebniz Rule at the same point in their calculations, though adherence to the Jacobi identity is a prerequisite for additional points to be awarded.
The 1786 Dowsing World Championships were a tense affair.
4. Synchronized divining: two athletes attempt to determine what score the panel of judges will award them by fashioning two dowsing rods into a pair of crude pendulums. Additional points can be awarded if the athletes simultaneously predict the same, correct, score. However, if any additional points are awarded they will render the original prediction incorrect and thus disqualify the athletes.
5. Synchronized, synchronized diving: two pairs of athletes, each in a different stadium, simultaneously perform dives. Judges pay no attention to discrepancies between the dives of each diver in a pair, but instead award points based on how similar the pairs of dives are to each other. However, video technology is not permitted and the judges must award points based only on their initial observation of each dive. The logistical difficultly that this rule presents are yet to be overcome by this otherwise hugely popular sport.
