Paula Radcliffe, chasing(角逐)a third London marathon title(冠军), says she has become a stronger
person after her terrible experience at the 2004 Athens Games.
Radcliffe, who failed to complete the Olympic marathon and the 10,000m last August, said: “Athens made me a stronger person and it made me care about criticism(批评).”
“In the past I wanted to please everyone, but now I am going to listen even more to the people around me.”She didn't care about criticism made at the weekend by Liz McColgan, who felt Radcliffe should
have rested and let her body recover after her failure in Athens.
“Liz is someone I look up to but she hasn't spoken to me last year and if she really cared for me, I'm
sure she would have contacted(联系)me.”
Instead Radcliffe won the New York City marathon just 11 weeks after Athens.
“In New York I wasn't in my best state but I did know I was good enough to win the race.”
Radcliffe insisted her only goal in Sunday's race would be winning a third title and not chasing world
records.
However, Radcliffe has not ruled out(排除)in the future chasing her “final” world record time and
questioned sayings that marathon runners have the ability in their career to produce only four or five
world-class times.
“I don't think that---although I can't put a number on it,” said Radcliffe. “That changes from person to person.”
Radcliffe is sure she can better her winning London 2003 performance some point in the future.
Following a successful three-month training period in the United States, the 31-year-old will chase a third
title on Sunday after her first victory in 2002 and again 12 months later.
Radcliffe clocked a time 2:18:56 in her first 42.2-kilometre race three years ago.
Afterwards she set a “mixed course” mark of 2:17:18 five months later in Chicago before lowering
that to a time of 2:15:25 in the 2003 London event.

D. Radcliffe had a 3-month training before the New York City marathon.
3. By saying “I can’t put a number on it “ , Radcliffe means she’s not sure ______.
A. if she has the ability to set a new world record
B. if she can win another race though she has won many times
C. how many times a marathon runner can set the world record
