We've rented from a certain baby-equipment place before, but I think it was a BOB or a BabyTrend, neither of which is showing up on the site. This is what they show for a single jogger though I thought I've read they're not actually joggers:
Safe, or keep looking? The front wheel locks or swivels; of course I'd run with it locked. Thinking 2-4 miles with 38lb DS a few times in a week.
I have the City Mini Double and you "could" do a slow 2 mile jog on an even, paved surface but it is definitely not what this stroller is designed for. But it is great for just strolling around...ours is very light and turns on a dime and it is the double.
