Koellner triumphed in the boys' 12.5 kilometres race with a time of 42min 47.3sec.

Fellow German Benjamin Erik Menz finished second in 43:59.1, while Ukraine's Stepan Kinash came third in 44:16.3.

In the girls' 10km competition, Remonnay prevailed by a margin of 2.9 seconds over Switzerland's Lea Meier with a time of 38:17.4.

Rounding out the podium was Russia's Sofia Tsyplukhina, who finished 41.5 seconds behind in third.

Also tasting victory today in Bosnia and Herzegovina was Austria's Magdalena Egger as she claimed her second Alpine skiing gold medal of the event by topping the girls' giant slalom standings.

Egger, who won the girls' slalom title on Monday (February 11), clocked an unrivalled two-run time of 2:16.38.

She becomes the first girl to achieve the slalom-giant slalom double at the Winter EYOF since Slovenia's Ilka Štuhec, now a two-time world champion in downhill, did so in 2007 in Jaca in Spain.

The silver medal went to Slovenia’s Rebeka Oblak in 2:19.00, while France’s Axelle Chevrier took the bronze in 2:19.02.

Russia's Ilya Yablokov leads the boys' figure skating competition after the short programme with 74.76 points.

Compatriot Anna Shcherbakova tops the equivalent girls' standings with 72.57 points. 

The free skating programme in both events is scheduled to be held tomorrow.
