Lol, that's awesome! Jackson LOVES to run too. It's his favorite thing. A walk can suffice but his energy doesn't get really worn out unless he RUNS!
I think it's great.
I will use rollerblades and bikes a lot of times when I visit over at my dads house and go for a run with Jackson. I don't have sidewalks/neighborhood at my house so I can't do it there but he loves it when I do it with him. It's easier for both of us with the rollerblades though rather than the bike.
But yeah, sounds like she's got the stamina and the energy for it!
