Japan’s 21-year-old Bouldering World Cup champion Miho Nonaka, a model of consistency this season, added victory in the annual adidas Rockstars event to her CV as she held off the strong challenge of 29-year-old defending champion Alex Puccio of the United States.

As the lights flashed and the music boomed in the Porsche-Arena at Stuttgart, Russia’s 29-year-old Ekaterina Kiprianova beat 20-year-old Serbian climber Stasa Gejo to bronze.

In the men’s event, victory went to the overall Bouldering World Cup champion of 2018, Jernej Kruder of Slovenia, who held off the challenge of South Korea’s 22-year-old Jongwon Chon, current world bouldering silver medallist and twice former winner.

Japanese climbers took the next three places, with Tomoaki Takata earning  bronze.

Earlier in the day, Japan’s 19-year-old IFSC world bouldering champion Kai Harada had missed out on a top six qualifying place for the final by one position.

There was no progression from the semi-final either by Iran’s 33-year-old Gholamali Baratzadeh, who finished in 13th position.

Canada’s 31-year-old multiple winner Sean McColl, who had hinted he was not in top shpe before the event begun, failed to progress from Friday’s qualifying.
