A WINNING surge off the final bend propelled Beaudesert schoolgirl Riley Day to a clear-cut 200m gold medal in the sapping 33 degree heat of the sun-kissed Bahamas.
It was the rising star's sixth sprint of a taxing seven-race program that delivered the high she had hoped for as a climax to the Commonwealth Youth Games.
Day's winning time of 23.42 was just .16 outside her personal best but she is unlikely to again encounter the periods of extreme heat over the past four days at the track unless she relocates to Cairns to train in high summer.
There was a double celebration for Day when just over 90 minutes later she anchored the mixed 4x100m relay for a second gold in an all-Queensland quartet with Caboolture duo Ella Connolly and Ben Schmidtchen plus Townsville's Jake Doran.
"It was only in the call room that Jake realised out of nowhere four Queenslanders had been put together. It all clicked in that mixed race, a real fun way to finish the Games,” said Schmidtchen, a long jumper swung in late when NSW sprinter Yadin Ngeng had a tight hamstring.
The value of this week for Day, 17, was always going to be her first taste of a multi-sport event in preparation for a full-on tilt at qualifying for the Commonwealth Games on the Gold Coast in April.
She has displayed a mature attitude at every point, from handling the disappointment of being pipped in the 100m to preparing properly with enough iced towels to fill a laundromat and the food to replenish when she felt flat on race-eve.
Day was in control in the 200, surged off the bend to pick up 2m on her two closest rivals and ran the straight as a clear-cut winner by 4m into a headwind.
Connolly (24.09) collected bronze.
"Seven races is definitely very tiring but when you get the results it's 110 per cent worth it,” Day said.
"I felt tired and rundown (after the semi-final win) the day before. Pastas, veges, meat ... I ate a lot to feel how I wanted to.”
Highly-regarded Neil Janse, 16, of Brisbane's Cavendish Road State High, was a decisive winner of the javelin with a throw of 74.19m.
In the ring, Queensland's Ella Boot claimed gold in the 60kg division over her Indian rival with a 3-2 split decision from the five judges
The Year 12 schoolgirl from Cooroibah on Queensland's Sunshine Coast has only been in boxing for two years yet has transferred her combat mentality from a long junior career in karate.
She left karate as a second dan black belt with multiple Australian championships in the youth ranks to take on the Olympic and Commonwealth Games opportunities that boxing offers.
