Fourth in Oceanias and seventh at national mountain bike championships, the 17-year-old apprentice builder demonstrated plenty of road potential having also ridden the Tour of Tasmania this week.

"Mountain biking is what gets you up that hill every lap," said the Launceston Mountain Bike Club member.

"In the Tour of Tas I got dropped in crosswinds on the Poatina stage so did not make the time cut but that gave me a couple of days to recover and probably helped for today.

"I'm still a mountain biker but road is good fun. I felt really strong on the hill every lap and with one lap left I said to myself 'righto, let's go'."

Northern Districts member Hamish McKenzie finished second to take out the under-17 category while Burnie's Dalton Stretton was third and McKenzie's father Paul won the masters.

Electrician Glenn Campbell proved the most switched on of the masters.

The 47-year-old father-of-two led home the oldest rider in the field, Legana neighbour and 1980 Olympian Michael Wilson, who turns 60 next month and added a second place to his son Josh's third in the final Tour of Tasmania stage the previous day.

Northern Vets' Andrew Brown completed the podium while reigning champ Andrew Howell icked himself up from a crash on the final corner to win C-grade.

"That was tough because it was very warm out there," said Campbell.

"It's a fantastic event and really good to win in your home town because I don't win much at my age."

Gold Coast-based Launceston couple Summer Dingemanse and Jono Butler returned home to finish first and second in the 5km running challenge.

Partly inspired by Rio Olympian Milly Clark ding the commentary, 25-year-old Dingemanse became the first female winner of the popular annual event.

"I love this event. It's a lot of fun because there's not too much pressure," said the former Launceston Christian School pupil who was the front-marker in the handicapped event.

"I did it last year and did not go out as hard this year. I just paced myself a bit better."

Butler, who is also Dingemanse's coach, had begun off a handicap of 2:30 while third place, off 2:45, went to Launceston's former rowing world champion Ali Foot.

"That was really hard," said Foot, who coaches Scotch Oakburn's rowing crews.

"The girls were rowing at New Norfolk this morning then we had a quick stop at the Brighton bakery before heading home and got here just in time."
