At JR's request, here is some information on the two-way events and how they are scored:
Racers leave the starting line at staggered intervals and their "time" starts at the green light on the starting tree. This time interval is stopped and recorded at the end of the first 50-mile leg. After everyone has completed the first leg, all cars are restaged and started back the other way in the same fashion as the initial start. Your second leg is timed the same as the first, and the two times are added together to determine the final score.
Example: 100 mph class--total elapsed time for a perfect score = 60 minutes (100 miles @ 100 mph). So, if your team runs the first leg in 31:00.0 minutes, they will have to run the return leg in 29:00.0 to achieve a perfect score. Official times of the first leg are not provided in between legs, so your own timing methods will have to be precise to calculate how much faster or alower you need to run the second leg.
In two way events, we have a "team" option, where the Driver and Navigator may switch places after the first leg. This is a lot of fun, and we offer a team award for the most accurate teams in the event.
In the event only one leg of the race can be completed due to any unforseen sircumstance, the scores from the first leg will be used to determine the winner.
If this sounds challenging, don't worry; we will be providing a "navigation and timing class" on the race weekend to all interested racers to help you get the hang of it.
