To be honest, the most enduro sport for me that I can do right now is kayaking, and I can do ~10 miles or so on flat water with my sorta tubby 10 footer in about 4 hours or so (with breaks)...and that's it, with a week's recovery afterwards.
Crazy distance for them, I'm impressed and a little jealous to be honest. Maybe I'll be there someday. :)))) <3
Yeah—it's literally a rainforest.

5-6 days is a reasonable amount if you are not insane. The second time I did it, there was a couple that ran it in two days. Only saw them at the start, but presumably they made. The reason they did 2 days is because you can pay to rent a tent + food about half way through. So they were running with just a two litter bottle of water and presumably some snacks.
But if you want to actually enjoy the views … even 7 days is not too slow
Don't think you need to precook stuff like quinoa. Can just cook it on an ethanol hobo oven pretty quick.
