Suffering from depression but desperate for "normality," Rachel Cullen found herself with failing relationships, the wrong career and a reliance on alcohol and chocolate to get her through each day. Stuck in an endless cycle of mental misery, she put on a pair of old trainers. She'd never been able to think of herself as a "runner" before, and the first time she forced herself out the door, she knew it would hurt. Everywhere. She just didn't realize how much it would heal her, too. Interspersed with Rachel's real diary entries, from teenage non-runner to London Marathon finisher (just months after giving birth), she questions if she really can outrun her demons.
