Also be self sufficient e.g carry all your own gear. There are support vehicles, but they are there for breakdowns and bbqs. Not for carrying your bags

Get some (as much as you can) experience riding gravel roads. Practice = seat time. 70-80% of this ride is not paved. So you really need to be comfortable on gravel

Porous from burning oil in the weld probably. I'd grind all the weld back, heat the hole area with gas to burn out the oil. Not red hot though or you'll shrink the axle. Then reweld

Clifton road was the first one with all the water. Noname road was directly after lunch. Maori Gully Road was after that.

Noted If we do it again in the future I have some kind of alternatives
