In fact, the couple met at the Fort Bend Fit Running Club and even got married at Mile 20 of the Boston Marathon.
That doesn't mean their love hasn't come without challenges. In 2013, Susie was near the finish line of the Boston Marathon when terrorists attacked the famed race.
Later that year, Susie was diagnosed with breast cancer. Remarkably, she recovered in time to run the Chevron Houston Marathon just months later.
Fast forward to 2020 and Dave will be running his ninth Houston Marathon, while Susie prepares to take on her nineteenth!
