I organized this global series of races. The data from those races, along with the tremendous amount of lobbying and meetings with federations, convinced the IOC. We got the women's marathon in the Olympic Games in 1984. That was my dream.

A lack of forgiveness is a waste of time and it's very enriching to forgive and move on but those are things that come with time.

When I forgave Jock Semple on Heartbreak Hill, I also got really cross with women. I couldn't understand why they didn't get it, why they didn't know that running was so cool and why they weren't in the race as well. Then I thought to myself "How stupid can you be? You've had so much encouragement and motivation and these women haven't."

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.

I don't have any kids of my own, quite by choice. There are two reasons for that. One, I had a sense of obligation for what my life would be and a vision of how to get that accomplished and it didn't include children. It's not that I don't like them, it's just that if you have them, they deserve 100 per cent of your attention.

All you need is the courage to believe in yourself and put one foot in front of the other.

When I was first running marathons, we were sailing on a flat earth. We were afraid we'd get big legs, grow mustaches, not get boyfriends, not be able to have babies. Women thought that something would happen to them, that they'd break down or turn into men, something shadowy, when they were only limited by their own society's sense of limitations.
