Obstacle races are having a field day; and women’s focused events like the new Mudderella series are getting in on the action. Women’s obstacle events are proliferating thanks to the obstacle racing and women’s running booms. Mudderella officially launched in June as the newest obstacle series for women. Their 5- to 7-mile races have 12 to 15 obstacles designed to test stamina, willpower and strength. Like the vast majority of women’s obstacle runs, there is no time clock. It’s not about speed, but about teamwork.
