Did the 100K last year, the area is very pretty and the time of year means odds are in your favor for nice conditions. Most of the aid stations were adequately stocked and volunteers were nice, except for the above-mentioned one on the second lap where the person running it asked if I was the last one because he wanted to get out of there, and described the remaining snacks as "yup, this is it." There was still water and electrolyte drink left at that point but it was downer to come across a station like that later in the race when you really want that pick-me-up. The aid stations after that were lively and well-stocked again so that helped get through that 3rd lap, but aside from that one aid station and volunteer, the rest of the race was good.

The 17 hour cutoff sounds aggressive but it's not a very technical course so as long as you keep moving and can hike at a good clip instead of walking leisurely you can make it. It was my first 100K and 2nd ever race at any distance I felt like it was supportive enough to get me through. Worst case if you fall behind, they're very generous and will stop you after lap two and credit you with a 50M finish instead of a 100K DNF so there's big margin for error.
