Athlete Jinson Johnson, who won gold in the 1500m and silver in the 800m event at the Jakarta Asian Games, has decided to focus only on 1500m in his quest for an Olympic medal at Tokyo in 2020.

"There's a better chance of winning the 800m medal at the Asian level. I plan to run both 800m as well as 1500m next year at the Asian Championships. But at the World events, it is better to focus on the 1500m. I'll run only the 1500m event at the Tokyo 2020 Olympics," Johnson said yesterday.
