Flat tire

Two nights ago hubs, big guy and I are out for a stroll before bed. Big guy is chilling in the stroller with eyes at 3/4 mast. The weather was gorgeous. We cut through a local park, which was pretty damaged by erosion. Then I hear a loud pop! And one of my tires on the jogging stroller burst. I've got a flat. I'm not even sure how to get it fixed. Can it be repaired? Or am I destined to have a bad wheel? When I figure it out, I'll let you know.
