The last sort of really low-key race I ran, I realized with about a hundred metres to go, that my heart just wasn't in it. I wasn't trying my hardest, I didn't care to compete against the girls I was up against. That spoke a lot about where my heart was taking me-which was off the track.

My story has resonated around the world. I am just Catherine, I just like to run. And I'll run with opportunities.

I felt so full of gratitude and humility that I clasped my hands in front of me, closed my eyes and said a silent prayer of thanks to God... I had at last achieved something I'd wanted for so long... My insides bubbled with happiness. It was a dream come true.

I think the greatest amount of pressure is the pressure I place on myself. So in a way I chose to be alone.
