Ezreal's adventures are not short. He doesn't leave in the morning and is back by evening to have his tea. Just counting the traveling time, it takes weeks. The ruins aren't exactly just standing next to cities either. Finding them is equally time consuming. It usually takes a month or more(usually more) before he returns to Piltover again. But then, he forces himself to stay there for some time, because he values preparation the most. Research, information, re-supplying, equipment maintenance(or buying new ones), as well as physical relaxation. Pushing the body constantly will only have negative results. He loves risks and pushing himself beyond his limits, but he finds no point in it if it's not actually his limit. If he isn't at 100% already, to then go beyond that.
