Some might know that I've run the Targa Newfoundland a couple of times. It's an epic race that's open to amateurs and there's nothing else like it in North America. The race is 5-6 days long depending on how you count the "prologue" day that's used for seeding/testing and has transits between the competitive stages. When it was introduced, the event ran all over the island. In 2012 (IIRC), the event was scaled back into a more compact form that got rid of some of the iconic stages further away from St. Johns. For 2023, it expanded back over the island.
A quick primer: in the high speed Targa division, cars are given a target time to complete a stage. If you take longer than that time, you get 1 penalty point per second. The times get more aggressive as the event goes on, so it's impossible to complete without taking some penalties - and the penalties never go away. There are also ultimate speed limits for safety reasons.
There are three main divisions: Targa 2 (fully prepped rally cars with FIA spec cages), Targa 1 (much less prep, no cage) and Grand Touring (basically, TSD without the games). The Targa 2 division gets the fastest target times and has the highest speed limit for fairly obvious reasons. There are a bunch of classes inside each of these divisions based on prep level and the age of the vehicle. Target times are set across the various classes to try to level the playing field, but it used to be biased towards older cars which is why there was a very successful BMW 2002 that took multiple overall victories about 15 years ago. The Targa 1 division is new for 2023 in an attempt to make the event more accessible.
Targa Newfoundland 2023 just wrapped up last weekend. It's the first time it's been run since 2019 and they brought back the full island-crossing experience. Unfortunately, there weren't a lot of entries. Only 2 in the full fat Targa 2 division. 4 entered the Targa 1 division, and 2 showed up the Grand Touring (basically TSD) division. The Tour group added 5 more entry fees. That's not enough to keep the event alive, as it costs as much to close a stage for 8 cars as it does for 80. When I first ran it in 2008, the field was nearly 70 cars. The lower entries mean higher entry fees, and of course that's a death spiral.
So if you want to run the Targa Newfoundland, do it in 2024. First, it'll help keep the event alive. Second, the current numbers are unsustainable so it may not survive much longer. Don't worry about classes, just do the safety prep and let your car fall wherever it ends up. Heck, rent a car and run Grand Touring using some kitchen timers from Walmart*. It's not a cheap event but it's a great bucket list event - better than going to Vegas to watch an F1 race for the same price. If you don't get out and do it, you may lose the chance.
* seriously, my Grand Touring sister team in 2011 relied more on kitchen timers than the Terratrip we'd installed
