Caroline Paul is no stranger to adventure. From mountain biking the Bolivian Andes to pitching a tent mid-blizzard on Denali, Caroline’s spent a lifetime chasing exhilaration.

Somewhere along the way, she noticed that the women adventuring alongside her kept disappearing. Not literally. And not because they wanted to stop having adventures. But because nobody gave them permission to keep adventuring as they got older.

Tough Broad: From Boogie Boarding to Wing Walking – How Outdoor Adventure Improves Our Lives as We Age is part science, part psychology, part love letter to every woman who’s been told she’s too old for something new.

We look at the five pillars of adventure, why they matter even as we age, what adventure means. And it’s not just base jumping or wing walking. Sometimes it’s an 80-year-old boogie boarding with her crew in the San Diego surf. Sometimes it’s learning to skateboard for the first time at 52. And sometimes it’s a woman in a wheelchair finding the edge of her comfort zone and pushing past it.

We share the research, and the hard-won takeaways from years spent talking to women who refused to slow down.
