Our neighbor was selling her $600 stroller for pennies on the dollar. It has been bliss to get an actual cardio workout - no more Laurel stopping every 2 feet to examine a flower or rock. Although we have toddler-oriented walks too, but this is strictly Mommy time. We took it for a 4 mile hike on a rocky trail on Columbus Day and those wheels just glided over everything in its path.
The kids are bundled up because when I leave for my walk around 11am, it's still only 45 degrees.
