Outside of cycling, Shayna enjoys spending time with her friends and family, which often includes road trips and various outdoor adventures. She also enjoys horseback riding, beach trips, and searching for the best food and coffee shops in the area. Additionally, Shayna is passionate about mentoring and inspiring others to lead healthier lifestyles through sports. She has hosted various community cycling clinics, including numerous events on Native American reservations. Shayna is also a member of the Oneida Tribe of Indians of Wisconsin, where she has family ties, and where she hosted a group ride event back in 2018. In conjunction with these events, she and her partner, Eli Ankou (of the Ojibwe tribe) started a non-profit organization in 2018 called the Dreamcatcher Foundation. This foundation is dedicated to empowering youth through sports, specifically football and cycling. It is also committed to raising awareness of the Missing and Murdered Indigenous Women and Girls crisis in North America.
