Four-time world champion underwent shoulder and elbow operations last winter

After winning the past four titles, a new women’s world shot put champion will be crowned in Beijing as Valerie Adams has announced she is to miss this year’s event.

The 30-year-old has claimed medals at the past five editions of the IAAF World Championships but feels she is not yet ready to compete at a major championship following the shoulder and elbow operations she underwent last winter.

Her 56-competition winning streak came to an end on her comeback in Paris in July as she finished fifth with a throw of 18.79m, almost two and a half metres down on her best recorded in Daegu four years ago.

“I want to inform you all that I won’t be attending the World Championships in Beijing,” the New Zealander announced via her Instagram account.

“I have thought about this long and hard and know it’s the right thing to do. For all those that know me, know how competitive I am and how much I love competing in the black singlet.

“This has been a tough comeback but I’m glad I made an attempt this season as it has just boosted my motivation more for the Olympics which has always been the main focus.”

The two-time Olympic champion added: “Deep down this is not easy but I’m a realist and know I’m not ready just yet. I still have stuff to work and it’s been a challenge since my surgery on my elbow especially as it has/is taking more time then I thought it would … But that’s life and I must roll with the punches and deal to this sucker.

“My right knee also needs some tender loving physical care and that will be attended to as soon as I hit NZ soil. But all in all I want to take this time to thank you all for the continued belief and support throughout my career especially in the last 10 months. No one said it would be easy but I’m a willing participant and will continue to fight and work towards defending my tittle in Rio 2016.”

Speaking ahead of the Anniversary Games in London last month, Adams had explained how her defeat in Paris had given her more “drive and determination”, with retaining her title in Rio her main target.
