Today’s guest Laura Philipp is a world-class professional athlete who has won 16 Ironman 70.3 races, 3 Ironman races and boasts the fastest Ironman debut time of all time for any woman. Laura was even invited to and participated in the legendary Hawaii Ironman, placing fourth at her first participation. She also has a very special way of training: she bases her training around her menstrual cycle and female physiology. In this episode, Laura talks with host Katja Bartsch about the benefits of having a natural menstrual cycle without hormonal interference as well as how she first got interested in menstrual cycle-based training and how she implemented certain changes to her lifestyle and training routines to maximize her performance. The two also discuss the ways that hormones fluctuate, how that can relate to training, and the effects of stress on the menstrual cycle. Listen in as Laura opens up about the research she says is still missing on hormones and training, why she gets most of her injuries in the second half of her menstrual cycle, and how to see your cycle as a gift to work with.
