The Go Girl Run Series is the premier all women’s marathon, half marathon, and 5K event series. Launched in 2012 by its parent company, Ultramax Sports, the Series has evolved into a true celebration of fitness, health, friendship, and sisterhood. Every detail of this Series is planned with the woman in mind. In its first year alone, the event attracted over 2,500 participants and spectators. Last season, we expanded to four cities and had over 10,000 participants and spectators. Quite simply, the women’s running movement and the half marathon distance across the nation is exploding. Go Girl Run is proud to take the lead in this movement!
