Lisa Markland and her husband Dave Markland completed the 10K for the Run, Walk & Roll event on the C&O Canal towpath that went from Darnestown to Potomac, Maryland and back. Her husband is a very healthy 62-year-old Coast Guard veteran but Lisa’s story is a bit unique, and why they chose this particular race challenge (for her, this was a true challenge in every way). She wanted to share it with us.
