The Go Girl Run Series is an 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. Because of this, Ultramax Sports combined the two and continue making the leap forward by expanding Go Girl Run Series to six cities in 2017.
