Bethany Hughes and Lauren Reed (calling themselves “Her Odyssey”) traveled through two continents starting in 2015 from Ushuaia in Argentina, and ending in Tuktoyaktuk, Northwest Territories, Canada. They traveled by hiking, backpacking, sea kayaking, river rafting, and canoeing across 14 countries, 18,221 miles. No, they didn’t do this all at once, but in multiple legs over almost seven years.
No book (yet), but this article describes some of their experiences. I love their goal of connecting with local inhabitants. Here’s the article in Paddling Magazine.
