Teenage sprint star Gout Gout has underlined his potential with more outstanding performances at the Australian All Schools Championships in Brisbane on Friday.

Only an illegal tailwind of 3.4 metres per second prevented the Queenslander's heat time of 10.04 seconds being recorded as a national under-18 record in the 100 metres at the Queensland Sport and Athletics Centre.

He later broke the national age record with a time of 10.17 — run with a legal wind reading (+0.9) — in winning the under-18 men's final, dipping under his previous personal best of 10.29.

"I've been chasing this national under-18 record for a while," Gout said.

"This was great atmosphere, this does wonders for track and I couldn't be happier."

Prior to Gout's run, the national under-18 record was 10.27, held by Seb Sultana.

Patrick Johnson holds the national record (all ages) of 9.93, which was set in Japan 21 years ago.

Johnson is the only Australian to have legally run under 10 seconds for the 100m.

Gout's reputation has snowballed this past year.

He has become a social media sensation even to casual observers of athletics who have gorged on viral videos of his track success.

Gout has claimed several age group records over the 100m and 200m.

The 200m is arguably his best event and in November he ran 20.29, which is the fourth-fastest time run by an Australian over the distance.

Gout won a silver medal in the 200m at the World U20 Championships in Lima last August.

The Queensland-based athlete is coached by Di Sheppard, who first spotted her charge when he was in year seven at Ipswich Grammar.

He will turn 17 on December 29 and will travel with Sheppard to the United States next month for a brief training stint with Olympic men's 100m champion Noah Lyles.
