Cheers all rigid bike it is :) my mate did it last year and i’m aware of the rough parts! There is also 4/5 of us going so shouldn’t encounter to many issues.
Kit list so far, some items we will likely pool so only 1 pump, 1 multi tool etc:
Inner tubes (x2) and patches
Tyre levers
Cable ties
Gorilla tape
Pump
Basic lights
Multi tool
Leatherman
Quick release chain link
Mobile phone & charger
Card and cash
Waterproof jacket
Riding clothes (washed each night)
A few detergent tablets for clothes washing
Clothing (2 x t-shirts, boxers, socks, 1 x trousers, hoodie)
Food bought daily night before
Also, thinking this for the clothes:

and this for the food / tools etc

They’re expensive though so open to suggestions on the packs!
