    In this comprehensive course, Sarah untangles the myths about what it is to be a cycling woman. The course begins highlighting the wisdom of women and the deep connection our ancestors had. Sarah’s teaching style is enthusiastic, knowledgeable and empowering. Hormones used to be a scary word for me as I didn’t feel like it was something I had autonomy over - rather every month I truly felt at the whim of my cycle. But through this course I have learnt how to be at the helm of my body.
