What is Competitive Highlining?

Competitive highlining is the elite discipline of slacklining performed at significant elevation (highlines are typically defined as slacklines ≥15 m off the ground, over canyons, between rooftops, or across mountain gaps). Governed by the International Slackline Association (ISA, founded 2012). Disciplines: (1) longest walked highline (distance record), (2) trickline discipline (aerial acrobatics + spinning moves), (3) speed walking (fastest crossing), (4) mono-lines (single strap). Modern highlines routinely span 100-500+ m; current world record ~2,800+ m (Andes, 2023). Uses 2.5 cm / 5 cm webbing under high tension (2-5 kN). Athletes wear leash + harness; falls result in swinging catch. Signature events: ISA World Championships (biennial), Highline Meetings (Petzen Slackline Festival, Sunwapta Highline Festival). Notable athletes: Alexander Schulz (GER, multiple distance records, 400+ m highlines), Faith Dickey (USA, women's champion + first woman to cross 100+ m), Louis Boniface (FRA, trickline champion), Théo Sanson (FRA, expedition slacklines), Andy Lewis (USA, super bowl halftime slacklining 2012).
