I ran this FKT attempt as part of training for an upcoming race. I've run this route quite a few times, but I really wanted to hit it hard. Felt great (although the final climb up Hard Times Rd was tough!). The map/GPX file from Trail Run Project worked perfect for navigation (there's lots of turns & different trails you could accidently turn on, so this is important).
I ran this attempt solo & unsupported.
