Olympic women's marathon champion Tiki Gelana said it has been a struggle to force the shocking images of the Boston bombings from her mind ahead of this weekend's London Marathon.
The Ethiopian told Press Association Sport: "It is not so easy [to put Boston out of your mind].
"As a human being you feel sorry for the people affected because of what happened. You think about it now and then."
"But I am here to run, I am an athlete," she continued. "London is a big marathon to win. Even with what happened in Boston, you come here to win. To win in London would mean a lot."
