Up in Orange County we called them "TSD" rallies.  Time, Speed, and Distance.
:-)  Usually run by the local SCCA club.

I ran in a bunch of them back in the 70's, best finish ever was a 3rd place.
Never bothered with stopwatches.  Lot of fun, but girlfriend/navigator and I
were usually not talking to each other by the end of a rally.  "LEFT in 1.267
miles at 22 MPH".  I meant "RIGHT".  Yeah, but you said LEFT!  On and on all
evening.  LOL

> In the USA rallies were/are time, distance, speed (TDS) events.  The total
distance is broken up into legs and it should take you a particular amount of
time to do the leg.  However, you do not know the distance for the leg nor
where the leg will end.  You also do not know what route you will be taking,
you are handed instructions less than a minute prior to your departure.  The
instructions are not the type that you can look at a map to determine where
you are going, at least for the rallies I'v done.  They also indicate a that
when you get to a certain point what average speed to maintain.
> Now to the stop watches, I am familiar with three watch boards.  There was
one watch for total time, started at the beginning of the leg. One was the
time for the current average speed.  The third was the ending time for the
last average speed section and for any specified stop times.  These along with
the instructions were all handled by the navigator who was also constantly
doing calculations to determine if you "were on time" or not so the driver
could correct their speed.  By the way he was doing these calculations with a
slide rule and using the dual Odometers for those who were really serious
about these events.
> For those not familiar with TDS rallies the difference between the time it
took you to do a leg and the it should have taken is your "error", early or
late and can not be made up.  The error for all legs are added up and the
lowest error wins.
