India's javelin stars will kick off the outdoor season at the Doha leg of the Diamond League on May 10 with a new sense of 'belief'. Leading the challenge will be world and Olympic champion Neeraj Chopra and his comrade-in-arm, Kishore Jena. The events, including the Federation Cup in Bhubaneswar on May 14-15, leading to Paris 2024 will also evaluate the returns from some intense overseas training under top coaches. Chopra and Jena, who produced a historic gold-silver finish at the Hangzhou Asian Games, have both qualified for the upcoming Summer Olympics in July-August, but Chopra, the poster boy of Indian athletics, believes a third javelin thrower - DP Manu - should make the Paris cut as well.
