From a family of runners, Chamberlain's father competed at the USA Olympic Trials in the steeplechase, as she ran in track and field at high school alongside her sister, Karissa.

She set a BYU record and became the fourth fastest NCAA all-time in the women’s indoor mile run with a time of 4:33.14 at the 2023 Razorback Invitational. [3]

Chamberlain was a member of winning BYU distance medley relay teams at the 2024 and 2025 NCAA Indoor Track and Field Championships.
