Cheryl was able to finish this "20 miles of hope and six miles of truth" that she calls "the most amazing thing I've done" with the help of her husband and an online community of runners, called the Maniacs.
And what comes around goes around. When Wynonna learned of how she had inspired Cheryl, she sent Cheryl her own note.
"I'm so proud of you," Wynonna wrote. "I can tell you've had a major transformation in many ways, and you are awesome. You're truly inspiring me as well. The day I saw your pictures, I was embarking upon a continuation of my own journey, and your story has encouraged me."
