her historic Calendar Year Triple Crown hike in 2018 when she hiked all three of those trails in one March-November season, making her the first female to do so.

She is the author of Thirst: 2600 Miles to Home (2019) chronicling her Pacific Crest Trail record and Mud, Rocks, Blazes: Letting Go on the Appalachian Trail (2021) about her 2015 AT record.
