Questions about races/qualifying

Hey guys, new to the community, ran my first Super last year and had a blast. Looking into doing a lot more events this year. I've been poking around the website and having some trouble finding information about qualifying for some of the larger events like the Death Race in Pittsfield VT, as well as information in general about what I'll need, etc. Is there a page or two that I'm missing that has deeper explanations about the other offerings than the regular sprint/super/beast? Definitely planning on at least getting the trifecta this year and hopefully more. Thanks in advance and sorry if I sound like an idiot
