Slacklining

Urbanlining or urban slacklining combines all the different styles of slacklining. It is practiced in urban areas, for example in city parks and on the streets. Most urban slackliners prefer wide 2-inch (5 cm) lines for tricklining on the streets, but some may use narrow (5⁄8 or 1 inch, 1.6 or 2.5 cm) lines for longline purposes or for waterlining. Also see the other sections of slackline styles below.

One type of urbanlining is timelining, where one tries to stay on a slackline for as long as possible without falling down. This takes tremendous concentration and focus of will, and is a great endurance training for postural muscles.

Slackline handstand

Another type of urbanlining is streetlining, which combines street workout power moves with the slackline's dynamic, shaky, bouncy feeling. The main aspects include static handstands, super splits—hands and feet together, planche, front lever, back lever, one arm handstand and other unusual extreme moves that are evolving in street workout culture.

Tricklining has become the most common form of slacklining because of the easy setup of 2-inch (5 cm) slackline kits. Tricklining is often done low to the ground but can be done on highlines as well. A great number of tricks can be done on the line, and because the sport is fairly new, there is plenty of room for new tricks. Some of the basic tricks done today are walking,[1] walking backwards, turns, drop knee, running and jumping onto the slackline to start walking, and bounce walking. Some intermediate tricks include: Buddha sit, sitting down, lying down, cross-legged knee drop, surfing forward, surfing sideways, and jump turns, or "180s". Some of the advanced tricks are: jumps,[2] tree plants, jumping from line-to-line, 360s, butt bounces, and chest bounces. With advancements in webbing technology and tensioning systems, the limits for what can be done on a slackline are being pushed constantly. It is not uncommon to see expert slackliners incorporating flips and twists into slackline trick combinations.

Highlining is slacklining at elevation above the ground or water. Many slackliners consider highlining to be the pinnacle of the sport. Highlines are commonly set up in locations that have been used or are still used for Tyrolean traverse. When rigging highlines, experienced slackers take measures to ensure that solid, redundant and equalized anchors are used to secure the line into position. Modern highline rigging typically entails a mainline of webbing, backup webbing, and either climbing rope or ultra-high-molecular-weight polyethylene rope for redundancy. However, many highlines are rigged with a mainline and backup only, especially if the highline is low tension (less than 4,000 N (900 lbf)), or rigged with high quality webbing like Type 18[3] or MKII Spider Silk.[4] It is also common to pad all areas of the rigging which might come in contact with abrasive surfaces. To ensure safety, most highliners wear a climbing harness or swami belt with a leash attached to the slackline itself. Leash-less, or "free-solo" slacklining – a term loosely taken from rockclimbing ("free" refers to free of aid equipment vs free from the slackline) – is not unheard of, however, with proponents such as Dean Potter and Andy Lewis.[5]

Split on a slackline

Slackline yoga takes traditional yoga poses and moves them to the slackline. It has been described as "distilling the art of yogic concentration". To balance on a 1-inch (2.5 cm) piece of webbing lightly tensioned between two trees is not easy, and doing yoga poses on it is even more challenging. The practice simultaneously develops focus, dynamic balance, power, breath, core integration, flexibility, and confidence. Using standing postures, sitting postures, arm balances, kneeling postures, inversions and unique vinyasa, a skilled slackline yogi is able to create a flowing yoga practice without ever falling from the line.

Slackline yoga has been covered in The Wall Street Journal,[6] Yoga Journal[7] and Climbing Magazine.[8]

Rodeo slacklining is the art and practice of cultivating balance on a piece of rope or webbing draped slack between two anchor points, typically about 15 to 30 feet (455 to 915 cm) apart and 2 to 3 feet (60 to 90 cm) off the ground in the center. This type of very "slack" slackline provides a wide array of opportunities for both swinging and static maneuvers. A rodeo line has no tension in it, while both traditional slacklines and tightropes are tensioned. This slackness in the rope or webbing allows it to swing at large amplitudes and adds a different dynamic. This form of slacklining first came into popularity in 1999, through a group of students from Colby College in Waterville, Maine. It was first written about on a website called the "Vultures Peak Center for Freestyle and Rodeo Slackline Research" in 2004. The article "Old Revolution—New Recognition - 3-10-04" describes these early developments in detail.

Highlining was inspired by highwire artists. The first successful highline walk is credited to 20-year-old Scott Balcom and 17-year-old Chris Carpenter who performed the first documented walk on nylon webbing highline. This highline, now referred to as 'The Arches' was approximately 30 feet (9 m) long and 120 feet (35 m) high located in Pasadena, California.[13][14][15] On July 13, 1985, Scott Balcom successfully crossed the Lost Arrow Spire highline.[16][17][18] In 1995, Darrin Carter performed unprotected crossings of the Lost Arrow Spire in Yosemite and The Fins, in Tucson, Arizona, on Mt. Lemmon highway.[13] On July 16, 2007, Libby Sauter became the first woman to successfully cross the Lost Arrow Spire,.[19][20] In 2008, Dean Potter became the first person to BASE jump from a highline at Hell Roaring Canyon in Utah.[21]

The record was set by four athletes between July 4 and July 6, 2021. Friedi Kühne, Lukas Irmler, Quirin Herterich and Ruben Langer (all from Germany) crossed a 2.1-kilometre (1.3 mi) slackline suspended more than 500 metres (1,600 ft) high between the Lapporten mountains near Abisko, Sweden.[22] All of them walked this line from beginning to end without falling, taking times from approximately 70–180 minutes.[23]

At a length of 110m and height of 200m, the longest free solo highline was walked at the Verdon Gorge in Southern France by German Slackliner Friedi Kühne.[24] The longest free solo highline by a female is held by Faith Dickey, who walked a 28-meter-long highline in Ostrov, Czech Republic, in August 2012. The line was 25 meters high.[25]

The highest slackline on record was walked by Christian Schou on August 3, 2006, at Kjerag in Rogaland, Norway. The slackline was 1,000 metres (3,281 ft) high. The project was repeated by Aleksander Mork in September 2007. Rafael Zugno Bridi currently holds the world record who walked a slackline between two hot air balloons.[26]

The current world record for the highest urban highline is held by Friedi Kühne, Mia Noblet, Gennady Skripko, Vladimir Murzaev, Maksim Kagin, Alexander Gribanov, and Nathan Paulin. All seven athletes managed to walk a 220m-long, 350m-high slackline between Oko Tower and Neva Tower 2 in Moscow, on September 7, 2019.[27]

The longest slackline walked by a woman, with a length of 305 metres (1,001 ft), was walked by Annalisa Casiraghi across a field in Schüpberg near Bern, Switzerland. The previous record had been set in September 2014 by Laetitia Gonnon, who walked 230 m (754 ft 7.1 in) in Lausanne, Switzerland.[28]

On 28 April 2019 in Kislovodsk, Russia, Friedi Kühne and Lukas Irmler from Germany walked a 975m-long, 200m-high slackline entirely with their eyes closed, ensuring this with a blindfold strapped over their eyes. Thus they broke the world record for the longest blindfolded slackline walk.[29]
