Since the beginning of women’s sports, there has been a struggle over who qualifies for the women’s category. So this week, we're sharing an episode of a new podcast we love, called Tested. Tested follows the unfolding story of elite female runners who have been told they can no longer race as women because of their biology. As they work toward the Olympics, they face hard choices: take drugs to lower their natural testosterone levels, give up their sport entirely, or fight. This episode asks: Would you alter your body for the chance to compete for a gold medal? You’ll meet runner Christine Mboma and hear about the difficult choice she faces. Find more episodes of Tested at https://link.chtbl.com/XReiimtOTested is from CBC, NPR’s Embedded, and Bucket of Eels.
