As a point of reference, on my fairly large sized and large bagged hardtail, I can carry just about 3 days worth of food before running out of space. It’s a pig to ride it like that but you can do it. 2 days is fine if a bit heavy.
From memory the Revelate designs guys have done 7 days self-supported in Alaska, with fatbikes and packrafts and giant packs, but one of them was eating raw butter for calorie density by the end. And they’re no amateurs!
