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.

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.

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.

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.

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

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.

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