A combination of these is ideal. 

It’s a good idea to always have a backup in your bag in case you get hungry. Muesli bars, long-life bread, tinned food, fruit and snacks (be aware that chocolate melts in the heat) are good to have on hand when you need to replenish your energy stores.

Some choose to add a daily supermarket visit to the route and visit a local place to eat in the evening. That way, you only have to concentrate on getting the fast carbs in your bag.

It’s also possible to cook outdoors at the area’s nature campsites. In this case, you must bring dried ready meals and cooking equipment.

And remember to fill up your water bottles before you leave! Fluid requirements vary from person to person and depend on the weather, but a basic rule is to carry one litre of fluid for 10 kilometres of walking.
