It's that time of year again, the time when I use the GRM forum as my platform for blathering on and on and on about this funny race on some Canadian rock.
First person reports from when I was racing.

So, let's start with the theory. Targa is split into five divisions.
Grand Touring is the easiest to understand. It's a TSD. But not the kind of TSD where the organizers are trying to get you lost or messing with your head. You are given a reasonably quick speed and the same set of navigation notes as the Targa classes. As the event goes on, the speeds go up and the times get tighter. The first day, you've got a big margin of error to finish without penalties - 30 seconds, I believe. By the end, you've got 3 seconds. This division is open to just about any street legal vehicle with minimal modifications. Maximum speed is 130 kmh (80 mph). It's relatively easy to drive but the navigator has a whole lot to do. A lot of Targa-class drivers think this is the easy baby class, but it's a different kind of hard.
Read a good first-person account.
Hot Tour is a fairly new addition. It's an opportunity for drivers of fast cars to drive the closed course without all the pesky rules or timing. Started to let cars like the Maserati MC-12 play, it's not a competition. In theory, the car's speed is controlled by a pilot car that leads them through the stage, but they reach higher speeds than the GT competitors do. I'm not sure how this one's going to evolve, it may not end well. We've already had an Enzo in the water...
Modern Division is the first of the Targa divisions. It's basically a very fast TSD with no penalties for arriving early. Competitors are given a base time (or average speed, as I tend to think of it) for each stage. They are given penalties for arriving later, but not earlier. As the week goes on, the base times get more and more aggressive and it's impossible to finish without penalties. For the first few days, you drive as fast as you have to in order to avoid penalties which is still awfully fast. By day three, you're basically going as quick as you can. There's an overall maximum speed of 200 kmh (125 mph) on this class for safety, although I don't think it's actually enforced. This class is open to cars built after 1984 (I think) with various levels of modification. All cars in the division are competing on a level playing field, with the same base times. Since this is a fast tarmac rally, safety gear is fairly intense, with full cages required. On a stage where the GT cars are given an target base speed of 80 kmh, the Targa cars will be given 130.
Open Division is the same as Modern, but for more heavily modified cars. Such as, oh, V8 Miatas. Basically, if your car is too heavily modified for Modern Class 3, you get put in Open. Otherwise, the rules and base times are identical.
Classic Division is very similar to modern, with the same modification classes. As you can guess from the name, it's for older cars. The big difference is the handicapping. The base time varies from class to class, adjusted for engine size, modification level and car age. The idea is to let every car be competitive, but this is a hard thing to pull off.
The race itself is five days long and covers something like 1400 miles, with approximately 25% of that being closed road competitive stages. At the end, the team with the least number of penalty points in each of the four competitive divisions is named the winner. There's no winner for Hot Tour, although there is a "spirt of the race" award for someone in that division.
Okay, there's the theory.
