Friedi Kuehne and Lukas Irmler, two German slackline athletes, set a new world record by walking a slackline stretched between two hot air balloons at an altitude of 2,500 metres, surpassing the previous record of 1,900 metres set in Brazil in 2021.
Both are veterans of the slackline world, holding multiple records. Irmler covered a 2-kilometre distance in 2019, while Kuehne set a highlining record in 2017 on a 110-metre line at a height of 250 metres.
