At the finish line of the 1967 Boston Marathon, one crabby journalist said it was just a one-off deal and women weren't going to run. Only a 20-year-old who had just run a marathon and was shot full of endorphin would say this but I said that there's going to come a day in our lives when women's running is as popular and as men's.

Five years after Boston 1967, I went to the Munich Olympics. I realized that major sponsorship could help me create the opportunity. I wrote a big proposal to Avon cosmetics on how creating a global series of women's races could lead to getting women in the Olympic marathon. People thought I was smoking poppy at the time. The longest event in the Olympic Games was 800m.

Jock Semple said "Oh the women ran well today the Boston Marathon and they deserve to be in the race." I had to laugh. I said "Well it took us five years but anyway, we're here." It pretty much changed everything.

I married the right guy later in life. Roger Robinson is just so wonderful but I was 40 and by that time he had been married and had his family. I realized how dangerous children could truly be. So I feel maternal when I see those women run.

What I've done in this older part of my life is I started foundation called 261 Fearless, named after my old ,1967 Boston Marathon, bib number.I thought we could create training and a communicative, non-judgmental platform, in a movement to let them know they're not alone. Then fearless women can reach out to help women who are fearful and take that first step using the vehicle of running because it's transformational. It works for every woman every time.

1967 race in Boston changed not just my life, but millions of women's lives. There are also things that, when you get older, resonate more.
