In fact, she thought it might be a blessing. She was far from peak form—recovering from illness and questioning her running future—and didn’t expect much of herself that day.

And what can athletes do to prevent and manage gut symptoms that occur during training and competition?

Yet as she became involved in the community and learned its history, she realized that the sport was largely built with white people in mind. Running While Black draws on Désir’s experience as an athlete, activist, and mental health advocate to explore why the seemingly simple, human act of long distance running for exercise and health has never been truly open to Black people.
