just enough for the day, water bottles, clothes etc...once the day is done depending on the type of multi day, you camp, eat, sleep then get up and do it again.
Some events are self supported so you would carry everything with you including the tent! Others the campsite is set up so you just have to rock up and crash out
My brother in law has just finished a self supported 170 mile across the Grand Canyon!!! He had to carry everything with the exception of water for the whole journey!!
