First of all, that's a BIG margin (somewhere around 3000-4000), but secondly did you mean feet instead of metres?Well I did 143km on an off-road expedition touring bike with somewhere around 3000-4000m of climbing
If by fully laden you mean 4 panniers and tent etc (like my avatar) then I would say take a couple days over it. It could be done in a day, but I'd work on no more than 15 km/h total speed including stops, so you are looking at at least 12.5 hrs, and I'd not want to be doing the same again the following day.
Of course if your fully laden is a couple panniers of clothing and bits and pieces then you should be able to ride that in a day![]()

Pffffffffff, the thought alone makes me tired...
We only managed 2150m on a 56k stretch, but that took us 8 hours (cycle time) and (11 hours in total).
