35.76km. *Second only to Lunokhod 2 (37km).

Note that taken about 9 years to do what the Apollo astronauts did in a few
days.

I'll take the Mark I eyeball on site when I can.

well if speed is what you want...... that can be done but science
along the way takes time

And exactly how many samples did *all* of the Mars rovers return to
earth? Zero.

Unmanned rovers "doing science" is quite inferior to manned missions
returning *many* samples to *far* better equipped earth based labs for
detailed analyses.
