I'll be watching and while I don't know how enthusiastic I'll be, I don't think the track itself will be a factor in my final judgement. I've sat on this opinion since the format was announced, but here we go:
I watch Cup, Xfinity, and Truck races because they have longer races than most other series that run on a closed track. There's time for strategies to play out, and for changing conditions to force them to evolve. Drivers have to manage tires, brakes, sometimes fuel, and other resources, and they have to endure. 'Hot' pit stops require the pit crews to play a big role.
From what I've seen when the top three series run similar 'heats and short stages' formats (All-Star and dirt races), today's event will not feature any of those. I have no problem with that for an exhibition race; I'll be watching, at least this first time. But I don't like this format at this level of racing, regardless of track size or permanence; it's why I've skipped the last couple of All-Star nights. Yes, the format is what dozens of short tracks do every weekend, and I enjoy it at those venues, but those tracks and teams don't have the resources to run a race of a few hundred miles and 3+ hours. I acknowledge the track size is one reason for using this format; it's too small to have a 40-car field and pits. They have to eliminate teams somehow, and a longer main is out because there's no room to change tires and refuel. But having Cup teams run this format is like restricting a master chef to making grilled cheese sandwiches; they may be the finest ones possible with the ingredients given, but I know there's so much more she could be doing.
