Having claimed his biggest track win in last year's Burnie Wheel, Melbourne's Jensen Plowright added his biggest road win in the Tour of Tasmania on Wednesday.
The 19-year-old attacked from the flag in Anne Street, George Town, on stage one and led the field over the line in Grindelwald three hours and 115.9 kilometres later.
He was eventually joined by three more riders in a break which enjoyed a lead of up to three minutes.
As it became clear that the break would succeed, climbing specialist and Tour of Indonesia runner-up Angus Lyons (Oliver's Real Food) appeared favourite but a slipped chain as he broke away on the final climb enabled the others to catch up and Plowright to sprint to the win.
"It was a long day out," said the beaming Melburnian.
"I went straight from the gate but no-one came with me and I was laughing a bit so was very pleased when the other guys came across.
"We did not think the break was going to make it but when we had two minutes going into the last climb I thought we probably would. After Angus dropped his chain and it came down to three of us I knew I was the fastest and the downhill finish suits me coming off the track."
Plowright said the win trumped previous victories in a Tour de Tweed crit and Tour of Southland stage.
"It's fantastic. I'm very pleased and quite surprised.
"I'm happy to get the yellow jersey and looking forward to putting it up in the pool room."
Plowright's Drapac Cannondale team consists of just four riders including Launceston's Oliver Martin and Zach Johnson.
"I cannot believe the break survived but I'm very happy for Jensen," said Johnson, 19, who has been training for the tour with Richie Porte.
"When the bunch sat up and we had a man in the break we knew we could take it easy."
