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.

When I go to the Boston Marathon now, I have wet shoulders—women fall into my arms crying. They're weeping for joy because running has changed their lives. They feel they can do anything.

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."

Jock Semple and I were at daggers drawn for five years, even though I kind of forgave him from the get-go. I knew he was an over-stressed race director, I knew he was protecting his race. It took five years because we had to do our homework - meaning we women - we did our legislative work and we officially got into the Boston Marathon. Then, all was forgiven by Jock Semple.

Life is for participating, not for spectating.

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.

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.
