Budhia Singh had planned to run 70km but doctors stopped him when he showed signs of extreme exhaustion.
"Budhia Singh completed the distance in seven hours and two minutes, which is an Indian record," his coach, Biranchi Das, said. "This is perhaps a world record, too."
Officials of Limca Book of Records, India's best-known record book, witnessed the run and said it would be included in next year's edition. The boy offered prayers before dawn at Jagannath Temple, a Hindu shrine in Puri town, before running to Bhubaneswar, the state capital.
Thousands stood along the highway, cheering him on. Budhia's father is dead and his mother, unable to support him, was about to sell him to another villager two years ago when he was rescued by the coach.
Mr Das spotted Budhia's talent when the boy entered a sports ground without permission, and was asked to run laps as punishment. When the coach returned five hours later, the boy was still running.
"I loved running today. I can run as much as I want," Budhia said.
Then he sucked his thumb.Last Mod: 20 Eylül 2018, 18:16
