Hunter gatherers would have been constantly on the move throughout the year. They would often be nocturnal to hunt and avoid some big beaties - remember Ireland was crawling with wolves until quite recently.
Not a great deal of spare time really UNLESS the diet was very rich. Off picking berries. Rooting around for roots. Building camps at each stop. Collecting fire wood to cook your food. Standing guard against predators. Going off on the hunt. Preparing food when caught. Making skins into clothes.
