Teenage world champion Kirani James has insisted that he is ready for the test ahead as he targets Olympic 400m gold in London.
The 19-year-old produced a massive upset to win gold at last year's world championships, becoming the youngest ever winner of the title.
In London, James will take on the fastest man in the world this year, LaShawn Merritt, but the youngster maintains that he is ready.
"We have everything in order," he told Reuters. "Everything is set and I am ready to run here in London."
James also admitted that he draws inspiration from Oscar Pistorius, South Africa's double-amputee 400m runner who will compete in London.
He continued: "He's done a phenomenal job. It takes a lot of courage to do what he does, so he is an inspiration to everybody, even to me. What he is doing, words can't describe it."
The 400m event begins on Saturday, with the final taking place on Monday evening.
