There is an expression among even the most advanced runners that getting your shoes on is the hardest part of any workout

When I got the women's marathon into the Olympics and we had races all over the world I thought, 'That's great, now we're heading towards total equality.' Then you see that there are women who are still not allowed to drive, get an education, or travel unless they have a male companion or can't carry their passport. There are those who are mired with incredible poverty in North Africa, the mid-east, South East Asia and there's a ridiculous amount of human trafficking.

Women is out because she's getting in her daily dose of empowerment, freedom and fearlessness. She has put on her freedom wings for 20 minutes or two hours. That's going to make her whole day right and her whole future hold up and seem entirely possible. The sense of her not having any limits, or any restrictions, to me, is so liberating. She doesn't have to prove anything.

If you feel positive, you have a sense of hope. If you have hope, you can have courage.

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.

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.
