Fully self-supported: you carry everything
Every other fact about this race is secondary to this one. There is no aid station handing you a cup of water or a gel at mile 15. You carry your own food, your own fluid or a way to treat water from the trail, and any gear you might need for a remote backcountry crossing, from the start at Piseco Lake to the finish at Wakely Dam. Once you commit at the dam, there are only two ways out: finish to the Piseco Airport, or turn around and go back the way you came.
That framing should shape your entire race, not just your pack list. A mechanical problem, a bonk, or a bad weather stretch has to be solved with what is already on your back, because nobody is coming to hand you a fix.
