MOUNT Isa's star sprinter, Mason Holm, has returned home from Sydney after competing at the National Under 20 Track and Field Championships.

Holm was optimistic of a good showing after producing impressive trial runs in the lead-up.

Competing in the 100m and 200m events, he failed to find his best and was unable to make the final in either event.

Holm made the task nearly impossible by missing the start in both events, a crucial mistake at events such as the nationals.

After working tirelessly at Sunset Oval every afternoon in preparation, the 18-year-old was disappointed with his performance.

"I just couldn't get into it, especially after missing the start," he said."It's disappointing, because I've been training well.

"I've just got to put it all behind me now, and look forward to the next event."

Holm's attention now turns to the state titles in Brisbane on Saturday.

"I just need to be quicker out of the blocks in Brisbane," he said.

"It's a lot easier when you get off to a good start.

"I need to keep my technique right and trust it, instead of trying to muscle it out if I miss the start."

Holm flies out to Brisbane on Friday, with a much more relaxed attitude.

"Hopefully I can stay focused and relaxed, and make the final," he said.

He will contest the 100m sprint and triple jump events, scrapping the 200m in Brisbane.
