Originally from Sacramento, Shayna started out as a competitive runner and triathlete from elementary through high school. In 2012, her senior year of high school, she decided to switch her focus from competing in multiple sports (track/cross country, triathlons, and cycling), to focusing solely on cross-country mountain biking. Through her four years of college, she competed in both road and mountain bike racing with the UCLA cycling team. She also raced with the BMC MTB Development team from 2012-2014 and the Liv Co-Factory MTB team from 2015-2016. The past couple years, Shayna switched her focus to road racing and gained valuable experience from racing in the pro peloton. She plans to continue making road racing her primary focus in the upcoming years and is very excited to be joining Twenty20 for another year, a team she knows will help her accomplish her goals.

Outside of cycling, Shayna enjoys spending time with her friends and family, which often includes road trips and various outdoor adventures. She also enjoys yoga, beach trips, and watching movies. Additionally, Shayna is passionate about mentoring and inspiring other women and young kids to stay healthy and active through biking. She even hosts community group ride events on Native American reservations a few times per year.
