Davis is also a blogger who writes about her interests in climbing, BASE jumping, yoga, and veganism.

Free solo climbing, or free soloing, is a form of rock climbing where the climbers climb solo without ropes or other protective equipment, using only their climbing shoes and their climbing chalk. Free soloing is the most dangerous form of climbing, and, unlike bouldering, free soloists climb above safe heights, where a fall can be fatal. Though many climbers have free soloed climbing grades they are very comfortable on, only a tiny group free solo regularly, and at grades closer to the limit of their abilities.
