Good luck Joe! It's all about the start, unless you get a bad start, then it's all about keeping your head and elbows up, passing on the inside, and don't look back! Head and elbows up is key, so don't forget to do that. And don't watch the starter dude walk off, just watch the light. That's it, the rest is simple. It's easy, no pressure. Good start, head up, elbows, and keep your weight centered over the rear wheel.
Oh, and bring something to scrub the tires with if they use any kind of traction aid, like coke syrup. The tires get gummed up after one run and you won't get traction with gummed up tires, so bring a grinder or disc sander to clean 'em off after each run.
That's it, tires, head, elbows, green light, weight centered...
