Highlining is a slackline discipline that is practiced at great heights, between mountains, buildings, bridges or whatever.
It is a great 💵 challenge and a slackline discipline in which the mental game and mindset are far more important than the technical and 💵 physical ability.
To really know what is highlining you probably have to try to stand on one or, maybe, if you 💵 get to see quite decent slackliners crumble when facing this new context and challenge, you'll get a pretty close idea 💵 of what it means for the one on the line.
This form of slackline provides an incredible adrenaline rush when tried 💵 for the first time and has a great impact on the spectators as well.
With the exception of highline freesolo, where 💵 the athlete is purposely unsafe, the highliner is permanently secured by a harness, attached to the main slackline line and, 💵 at the same time, to a lifeline, called the backup.
