When I finished the Boston race in 1967, there were two things I wanted to do. I wanted to become a better athlete because my first marathon was 4:20. In those days, that was considered a jogging time and I knew people were going to tease me. But I was more fascinated with what women could do if they only had the chance.

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.

Talent is everywhere, it only needs the opportunity.

Most people don't know this but over the course of time, the official of the race in 1967 in Boston, who attacked me Jock Semple and I became very good friends. That gave me a whole new perspective on forgiveness.

I said that there's going to come a day in our lives when women's running is as popular and as men's. Looking back, I obviously had a great sense of vision. And I was right.

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.

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.
