Karoline Sinnhuber kann sich mit dem Highball „Knocking on heavens door“ im Sundergrund im Zillertal ihren zehnten 8A+ Boulder  in diesem Jahr sichern. Insgesamt hat Karo auch noch fünf 8B-Boulder auf ihrem Konto. Erst Ende November konnte Karo im gleichem Gebiet „Drischiebl right“ klettern.

„ I was thinking about that highball already a few years ago and already checked it out twice on the rope, but I was just too weak for the hard crux part at the beginning. The crimps are really small and you have bad footholds. This time I found a different beta for the start and as I could do all the moves on the rope I decided to give it a go. I’m glad for not making the experience of dropping down from the „point of no return“.  Massive line!
