Women in Running: Breaking Barriers & Fueling the Future

For decades, women were told running wasn’t for them. They were warned it was too dangerous, too strenuous, and even "unladylike." Some believed women’s bodies couldn’t handle long distances, while others claimed that running a marathon could cause permanent harm.

But women ran anyway.

They ran without permission. They ran without recognition. And eventually, they ran right through the barriers placed in their way.

From Bobbi Gibb, who became the first woman to run a marathon by sneaking into the Boston Marathon in 1966 (The Sports Museum), to Kathrine Switzer, who made history in 1967 by officially entering and defying race officials trying to pull her off the course (Kathrine Switzer), women have fought for their place in running every step of the way.

Fast forward to today, and women athletes aren’t just running marathons—they’re winning ultramarathons, setting endurance records, and proving time and time again that they belong on every starting line.

Every female runner deserves the best running fuel to power their miles. Whether chasing a new PR, tackling a marathon, or hitting the trails for pure joy, the right running fuel options make all the difference.
