I guess they meant 3km through uneven ground in a forest.

Definitely this, 3km across rugged terrain is nothing like 3km on a sidewalk.

I'm pretty sure tree planters, a common forest job, cover more than 3km in a shift.

Do they work for kibble?

It's usually piece work at pennies a tree.

That’s rough... I think I’d actually prefer kibble!
