What I know of terriers is that they have loads of energy and tend toward the hyperactive. They need lots of stimulation or their behavior can degenerate into destructive, obsessive ways. I lived with a Jackabee (half beagle, half Jack Russel), why people intentionally breed these, I have no idea, as she had all the bad traits of both breeds! Don’t get me wrong, though, she is a highly intelligent dog, eager to please, and very easy to train (with no treats and only praise, which impresses me a lot). However, she really needs a lot of stimulation or her bad behaviors increase. I tried to work with this by getting her a puzzle treat ball, teaching her new “tricks”, and getting her to run out as much of that energy as possible. I know you run, so this may be not so much of a problem, as it would be really good for a terrier to get that kind of exercise to balance out their excess energy.
