Marianne C. Bohr, published author and award-winning essayist, married her high school sweetheart and travel partner. She follows her own advice and hits the road at every opportunity. She wrote her first book, Gap Year Girl: A Baby Boomer Adventure Across 21 Countries, over the course of the yearlong sabbatical she and her husband took to explore Europe. The Twenty: One Woman’s Trek Across Corsica on the GR20 Trail, is her second book. Marianne lives in Park City, UT, where—after decades in publishing, and then many years teaching middle school French—she now skis, hikes, and writes. She lives in Park City, Utah.

Marianne Bohr and her husband, about to turn sixty, are restless for adventure. They decide on an extended, desolate trek across the French island of Corsica—the GR20, Europe’s toughest long-distance footpath—to challenge what it means to grow old. Part travelogue, part buddy story, part memoir, The Twenty is a journey across a rugged island of stunning beauty little known outside Europe.

From a chubby, non-athletic child, Bohr grew into a fit, athletic person with an “I’ll show them” attitude. But hiking The Twenty forces her to transform a lifetime of hard-won achievements into acceptance of her body and its limitations. The difficult journey across a remote island provides the crucible for exploring what it means to be an aging woman in a youth-focused culture, a physically fit person whose limitations are getting the best of her, and the partner of a husband who is growing old with her. More than a hiking tale, The Twenty is a moving story infused with humor about hiking, aging, accepting life’s finite journey, and the intimacy of a long-term marriage—set against the breathtaking beauty of Corsica’s rugged countryside.
