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.

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.

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."

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.

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.

If you are losing faith in human nature, go out and watch a marathon.
