Hi, I'm Janie
Olympic sprinter, former midwifery student, and your Performance Sister.
I've been where you are. Standing on the track wondering why some days I felt invincible and others I questioned everything. Frustrated by the lack of information about how my cycle affected my training. Tired of fighting my body instead of working with it.
After years of research, education, and real-world testing at the highest levels of sport, I've created what I wish I'd had when I started my athletic journey.
