uk bug out, how long would you last ???

[Tarrel]

10-12 days before needing a re-supply of food, either foraged, hunted or scavanged. If that's possible, then on-going really, until something breaks irrepairably or wears out, or I get injured or ill.

My bug-out equipment is basically the same as my backpacking gear; a lightweight tent suitable for year-round UK conditions in all but the highest locations, sleeping mat, decent sleeping bag, trangia and fuel, dried food, first aid kit, change of clothes, extra warm layer, decent waterproofs, compass, gloves, hat, appropriate maps, knife, fire lighting kit, water bottle, fishing rod.

None of this is really time-dependent apart from the food and fuel. Your body will continue to operate provided you have food, are hydrated, stay dry and stay reasonably well insulated.
