How energetic are these puppers?

We used to have an Irish setter. I would have to run her about 10 miles a day. My life motto at the time was “a tired dog is a good dog.” I know wolfhounds are also prey driven but I keep seeing mixed “reviews.” Some say the dogs are couch potatoes and others say they need a solid 45 minute run daily with a middle ground of some walks with being able to run around a yard. We have a 75’x52’ yard. It was good for a tired out setter, but if I couldn’t run her one day, it was way too small.
