Vexed canine-like determination propels Kennedy, the pole vault queen, as she defends her world title.

Nina Kennedy, the reigning Olympic pole vault champion, is determined to defend her title at the upcoming World Championships in Tokyo. However, the Australian athlete faces a unique set of challenges, having not competed since her gold-medal victory in Paris last year due to a hamstring injury.

Kennedy underwent surgery after suffering three strains in six weeks, and the rehabilitation process wiped out her entire build-up to the September 13 to 21 world championships. Despite these setbacks, Kennedy is embracing vulnerability and is focused on returning to competition.

The 28-year-old athlete, who has only three years left at the highest level, is unsure of her current abilities but is optimistic about her chances. Kennedy estimates she is currently at about 80% fitness after six weeks of training, and she does not expect to be at her peak fitness for the Tokyo event.

Kennedy is unsure if she will be able to nab a spot on the podium, but she is determined to give Tokyo a "red, hot crack." The Australian pole vaulter sees herself as the best athlete out there and is aiming to challenge Yelena Isinbayeva's long-standing world record of 5.06m.

In an attempt to achieve this goal, Kennedy has been working closely with her sports psychologist to adjust her goals and focus on the process. Kennedy is also preparing for the event without any lead-up competitions, as she has skipped all Diamond League meets.

Despite the challenges, Kennedy remains hopeful. She believes that a first-attempt clearance above 4.80 metres might be enough for a medal in a post-Olympic year. Kennedy's personal best is 4.91m, and she hopes to become the fifth woman to clear the five-metre barrier.

Kennedy describes herself as having a "mongrel" and a "dog" inside, expressing her determination to return to competition. If it were earlier in her career, Kennedy might have skipped the event, but she is now approaching it with a sense of determination and resilience.

Accompanied by her trainer during her preparation for the World Championships, Kennedy is entering Tokyo on a wildcard. Ultimately, Kennedy aims to challenge Isinbayeva's world record and make history in the world of pole vaulting.
