In the 2011/12 season Runggaldier showed himself in increasing form and was able to record constant point gains in the Continental Cup . At the Nordic Junior World Ski Championships in Erzurum in 2012 , he was 29th in the Gundersen singles after jumping, before he won the junior world championship ahead of Manuel Faißt with an excellent mileage on the trail . Together with Samuel Costa , Roberto Tomio and Manuel Maierhofer , he won the silver medal with the team, which was the first medal ever for an Italian relay at a major international event in Nordic combined. In the sprint, it was only enough to finish 19th. Just a week later, in Val di Fiemme, he finished second for the first and only time in his career on the podium in the Continental Cup. He finished the overall ranking of the second highest competition series in 27th place.
In the following years Runggaldier competed regularly in the Continental Cup, but occasionally started unsuccessfully in the World Cup. At the beginning of February 2013 he was part of the Italian relay in Sochi , which finished ninth in the World Cup race. Due to the lack of squad width in the Italian team, he was repeatedly used in team competitions despite the lack of results. At the Nordic World Ski Championships 2015 in Falun , Runggaldier was in the squad, but was not used outside of training. After the 2016/17 season, he announced the end of his career.
