Her writing has been featured in Women’s Running Magazine, Self Magazine Online, Outside Online, and Runner’s World Magazine. In 2018 she was chosen as a National Geographic Adventurer of the Year, and in early 2020 appeared on the Kelly Clarkson Show and Access Daily, and most recently was featured on the Today Show.
