Longline slackline, a never ending challenge
Longline slackline is category or branch where the challenge is to walk longer and longer lines. More tensioned or saggy, with higher or lower anchors, the focus is always the same: sending the line". What determines if we are doing slackline or longline (as a distinct kind of slackline) is just line lenght. From 40 meters it can already be considered a longline.
