The Queechy 14-year-old claimed the under-16 division as Launceston athletes dominated the 1500-metre races on home soil at the Tasmanian All-Schools Track and Field Championships.

On a rainy day at St Leonards, Eccles charged home in 4:30.70 to the delight of his coach, Rio Olympian Milly Clark, and despite running 5km in the morning in the Launceston Park Run.

"It was a nice jog warm-up," he explained.

"I maybe had a little fatigue from that but I still did a PB by two seconds. My family have done about 170 park runs between us so it's an everyday thing for us all to take part. I've been doing it since I was nine and I love it."

Eccles said he closely followed the advice of Clark, who is on an altitude training camp in the US as she seeks selection for the Tokyo Olympic marathon.

"She's got me on a new training course of 70km a week. I came back from cross-country nationals and said quite a few of the Queensland competitors were doing 100km a week. But she told me it was more important to get the right volume and that if I do I will run as quick as her so I'm hoping I can reach her level."

Kings Meadows 15-year-old Abbie Butler made it an under-16 double for Launceston state schools before former Riverside High and now Launceston College phenomenon Sam Clifford completed a hat-trick in the under-18 boys' race.

"I was going to take it easy because I've got two more races today but I felt really good and went and got a PB," said Butler who, like all winners, qualified for the national titles in Perth in December.

"It will be hot there but I'll give it a go. My pet event is steeplechase and I got a silver in that at nationals this year."

Butler's day improved even more when she ran 6:47.73 in the 2000m to break state records from under-16 to 20 as second-placed Ella Atkins (Fahan) broke Butler's under-15 record.

Clifford was able to utilise a new race tactic as he remained on course to add to his bulging list of national titles.

The 17-year-old, who represented Australia at this year's world cross-country championships in Denmark, ran a cagey 1100m before producing a kick of Eric Cantona proportions to storm home on the final lap, winning in 4:14.30.

"I've practised that sort of surge in training a lot and I've run in national races which have been very tactical so it's good to have the confidence to go like that.

"They were hard conditions which changed every lap but I thought it was best to go with a lap left and I'm really happy with that."

The championships, which continue on Sunday, act as the state team selection for those in the under-14, 16 and 18 categories.

More than 300 athletes are taking part with the program running until around 3.30pm on Sunday.

Jessica Bray, of Mount Carmel College, threw 38.68m in the under-14 girls' javelin to break a record set 22 years ago. Will Robertson, of Rosebay High, broke the under-16 boys' 5000m record and Zoe Laurenson, of Taroona High, established an under-15 record while competing in the under-16 pole vault.
