GirlTrek, the largest public health nonprofit for African-American women and girls in the United States. With nearly 1M women in the movement, GirlTrek encourages women to use walking as a practical first step to inspire healthy living, families, and communities. As women organize walking teams, they mobilize community members to support monthly advocacy efforts and lead a civil rights-inspired health movement. Beyond walking, GirlTrek’s active members support local and national policy to increase physical activity through walking, improve access to safe places to walk, protect and reclaim green spaces, and improve the walkability and built environments of 50 high-need communities across the United States. With Partnership for a Healthier America, The Centers for Disease Control, Stanford Prevention Research Center, The American Council on Exercise, Safe Routes to School National Partnership, and The Sierra Club, GirlTrek has developed a world-class training for African-American women to serve as health professionals in the areas of fitness, mental health, nutrition, and environmental stewardship. GirlTrek’s mission is to inspire one million African-American women and girls to develop a daily habit of walking.
