A WALLAN family has swept through the Ski Racing Australia Australian Speed and Marathon Championships at Lake Jindabyne last weekend, taking home four national titles between them.

Courtney Grech won in the Marathon Women’s class with mother Jenny driving and sister Melanie observing, while Melanie won the Under 30 Women’s class with fellow Wallanite Ross Harris observing.

Their father Kevin Grech also brought home gold, winning the 60mph Men’s Social class.

Courtney’s marathon event saw her complete six laps of roughly seven nautical miles with each lap completed on a different type of ski with increasing levels of difficulty.

Racers start on a ‘social’ ski, which is very similar to what’s used recreationally and progress through different combinations of finless or bindless skis before the final lap is completed on a ski with no bindings or fins.

“The last one is literally a fence paling,” Mr Grech said.

“Courtney can do about 85mph (136km/h) on her social ski and as she goes through, on the plank she’ll do about 50mph (80km/h).

”Courtney and Melanie are currently in their second campaign working towards a birth in the 2019 World Championships in Vichy, France later this year.

Mr Grech said both have a shot after their first selection races at Lake Jindabyne.

“In their first selection race, Courtney finished fourth with a fall after she was in the boat for at least 10 minutes while they made sure she didn’t break anything. Melanie came through in sixth place which we were happy with,” he said.

With six more selection races to go, the Grech family will travel to Robe, South Australia, Botany Bay and Lake Mulwala.

Courtney and Melanie are currently training for the Southern 80 in Mildura and have been invited to train with current world champion Ben Gulley in Brisbane.
