Sport climbing



Sport climbing is a style of rock climbing that relies on permanent anchors fixed to the rock, especially bolts, for protection. Sport climbing places an emphasis on gymnastic ability, strength and endurance, while virtually eliminating the need to place protection while climbing. Also see Free_climbing.

A route suitable for sport climbing has pre-placed bolts following a line up a rock face. Sport climbs are typically between 20 and 120 feet in length, and have eight to twelve bolts (some routes may have as few as three bolts, while other routes may have twenty-five or more).

Sport climbing can be undertaken with relatively little equipment. Equipment used in sport climbing includes:

* A dynamic rope
* Quickdraws
* A belay device
* Climbing harnesses for belayer and climber
* A few runners
* A helmet is recommended
* Climbing Shoes and chalk bag are normally used, although not technically necessary

To lead a sport climb is to ascend a route with a rope tied to the climber's harness, and with the loose end of the rope handled by a belayer. As each bolt is reached along the route, the climber attaches a quickdraw to the bolt, and then clips the rope through the hanging end of the quickdraw. This bolt is now protecting the climber in the event of a fall. At the top of sport routes, there is typically a two-bolt anchor that can be used to return the climber to the ground or previous rappel point.

Because sport routes do not require placing protection, the climber can concentrate on the difficulty of the moves rather than placing protection or the consequences of a fall.

Sport climbing differs from traditional climbing with respect to the type and placement of protection. Traditional climbing uses mostly removeable protection (such as cams or nuts), and tends to minimize the usage of pre-placed protection. Sport climbing typically involves single pitch routes, whereas traditional climbing can include single-pitch routes as well as longer, multi-pitch ascents. There are areas like El Potrero Chico that feature multi-pitch sport climbs, but longer routes generally lack pre-placed anchors due to economical, logistical or ethical reasons.

The drilling required to insert expansion bolts invariably damages the rock this being the main reason, that traditional climbers disdain the use of bolts.

Rock types that produce good sport climbs include limestone, granite and quartzite, though sport climbs can be found on almost all rock types.

Ratings

Sport climbs are assigned subjective ratings to indicate difficulty. The type of rating depends on the geographic location of the route, since different countries and climbing communities use different rating systems.

The Ewbank rating system, used in Australia, New Zealand, and South Africa, is a numerical open-ended system, starting from 1, which you can (at least in theory) walk up, up to 34 (as of 2004).

The French rating system considers the overall difficulty of the climb, taking into account the difficulty of the moves and the length of climb. This differs from most grading systems where one rates a climbing route according to the most difficult section (or single move). Grades are numerical, starting at 1 (very easy) and the system is open-ended. Each numerical grade can be subdivided by adding a letter (a, b or c). Examples: 2, 4, 4b, 6a, 7c. An optional + (no -) may be used to further differentiate difficulty. Many countries in Europe use a system with similar grades but not necessarily matching difficulties. Sport climbing in Britain and Ireland uses the French grading system, often prefixed with the letter "F".

In the United States, the Yosemite Decimal System is used to rate sport climbs. Current grades for sport routes vary between 5.0 (very, very easy) to 5.15 (ridiculously hard), although the system is open-ended. Past 5.10, letter grades between a and d are sometimes used for further subdivision (e.g. 5.11a or 5.10d). Pluses and minuses may also be used (e.g. 5.9+ or 5.11-).[1] Originally, the YDS rating was designed to rate the difficulty of the hardest move on a given route.However, modern sport grades often take into account other features such as length and sustainedness.

Terminology

Sport climbers have developed their own terminology. For example, sport climbers have terms to categorize a successful climb based on the number of attempts and pre-existing knowledge of a given route:

* An ascent is considered an onsight if climbed the first try, without falls and without prior knowledge of the route.
* An ascent is considered a flash if climbed the first try, without falls but with some prior knowledge such as, but not limited to, watching another person climb it or discussing it with another climber.
* An ascent is considered a red point once a climber has attempted a given route and failed to climb it on the first attempt, but succeeded on a subsequent attempt while placing quickdraws.
* An ascent is considered a pink point once a climber has attempted a given route and failed to climb it on the first attempt, but succeeded on a subsequent attempt while climbing on pre-placed quickdraws. In some climbing communities, a pink point is considered to be a red point. In other climbing communities, this term has been abandoned entirely.

Routes that are at or above the individual climber's skill level often require working to red point (e.g. "We spent the summer working Ro Sham Po at the Red River Gorge in Kentucky."). A climber may return to a climb between two and hundreds of times to work out the moves, memorize the movements, and develop the strength and stamina required to complete the route. It is not uncommon for climbers to work routes for months or years.

A route that is being worked is considered that climber's project. Upon success, a climber is said to have sent a given route. (e.g. "Pete was working Ro Sham Po all summer, and in October he sent it.") The term can be used in the present tense as send. (e.g. "We were all yelling at Pete, 'send it!'")

Prior knowledge of a route passed between climbers is referred to as beta. Beta can be information about difficult moves, specific sequences, or any other information that aids in ascent. In particular, a climber may be interested in getting beta for the crux of a route. The crux is the most difficult section of a route. (e.g. "Pete got a bunch of beta for the crux moves on Ro Sham Po from Bill, who sent the route last year.")

Some of the terminology described above was developed by sport climbers, and has been adopted by other forms of climbing, such as bouldering and traditional climbing.

Ethics

The ethics climbers adopt toward their sport are not always steadfast, and they often depend on the venue. The following examples are merely outlines that do not always hold true.

Bolting

Whether a route should be bolted as a sport climb is often in dispute. In some areas, including a large part of the United States, if a route cannot be safely climbed with the use of traditional gear, it is acceptable to bolt it. However, in much of the U.K., similar bolting is widely considered unacceptable. Additionally, the method of bolting may often be challenged. Many early sport routes were bolted by the first ascentionist, on lead. However, it is now considered acceptable in most areas to place bolts while rappelling, before climbing the route.

First Ascents

Sometimes, a newly bolted route is considered "red tagged," and ethics dictate that the person who bolted the route should be the only climber to attempt it until they can send it. Other times, the bolter will allow the route they developed to become an "open project" that anyone can try. Ascents of reserved routes have led to a number of controversies in the sport climbing world.

Chipping, Comfortizing, and Reinforcing

Changing the natural features of rock is often frowned upon, but in many parts of the world it is still accepted to some extent. At some areas, "chipping" of the rock with a chisel or similar tool to create a hold that did not exist naturally is considered acceptable. This is particularly true in some quarries as well as some European crags. However, at many other areas, local ethics absolutely forbid this.

Comfortizing holds often involves aggressively cleaning a route to the point where sharp holds have been filed down, often making them somewhat easier to use. While many climbers frown on this, in some areas comfortizing is considered acceptable to a point.

Reinforcing rock with glue is the most widely accepted modification to natural features in the sport climbing world. When a popular route is climbed over and over, holds may become looser and closer to breaking. Sometimes, these holds will be reinforced to prevent them from breaking. Other times, if a hold entirely breaks off, it may be glued back on. In most areas, these practices are considered acceptable if done neatly.

Sending

Sometimes, an ascent or the style in which it is done will come into dispute. For example, a leader who experiences tension on their rope from their belayer while climbing without falling may have not made a valid ascent, through no fault of their own. Additionally, the line between an onsight and a flash is often disputed. Some climbers consider any knowledge of a route, including its grade, to be beta that invalidates an onsight. However, other climbers will go so far as to belay another climber on a route and still claim that they did not have enough prior knowledge to move from the onsight realm to the flash realm.

Not Sending

If a climber fails to onsight or flash a route, they may decide to "work" it by attempting to climb it despite falling and hanging on the rope. However, at popular destinations, multiple parties of climbers will often line up to try a route. A climber working a route may spend an inordinate amount of time on it, preventing other parties from climbing it. This is often frowned upon, particularly if the climber is toproping rather than leading.

Lead climbing


Lead climbing is a climbing technique used to ascend a route. This technique is predominantly used in rock climbing and involves a lead climber attaching themselves to a length of dynamic (stretchy) climbing rope and ascending a route whilst periodically attaching protection to the face of the route and "clipping in" to it. The lead climber must have another person acting as a belayer. The belayer has multiple roles: holding the rope in the event of a fall, and paying out or taking up rope as the climber moves.

As lead climbing does not require a pre-placed anchor at the top of the route, it is often seen as less restricted than top roping. Also, because a lead climber does not have an anchor point above them whilst climbing, only the limbs and body of the climber are used to effect upward progress. Protective devices are only placed to catch the climber in the event of a fall.

Lead climbing is an advanced technique, and is rarely practiced by novice climbers.

Lead climbing basics

When lead climbing, the lead climber or leader wears a harness tied to one end of a rope. The leader's partner provides the belay, paying out rope as needed, but ready to hold the rope tightly, usually with the aid of a belay device, to catch the leader in the event of a fall. The lead climber ascends the route, periodically placing protection for safety in the event of a fall. The protection can consist of pre-placed bolts and pitons, to which the climber clips quickdraws, or removable protection such as nuts and spring loaded camming devices which are carefully secured by the climber into cracks or other features. Distances between pieces of protection can range from three to forty feet or more, although most often the distance is between six and twelve feet.

At any point, the leader can fall at least twice as far as the distance to the most recently placed protection. If a leader is ten feet above the last piece of protection, a fall will be a minimum of twenty feet. Realistically, the fall would likely include several more feet due to rope elasticity and slack and give in the overall mechanical system. Any time a lead climber approaches twice the height of the last piece of protection, there is danger of a ground fall in which the falling climber hits the ground before the rope goes tight. In such a case, the rope does no good at all. The severity of a fall which is arrested by the climbing rope is measured by the fall factor: the ratio of the distance fallen to the amount of rope between the climber and the belayer. A fall of 20 feet is much more severe (exerts more force on the climber and climbing equipment) if it occurs with 10 feet of rope out (i.e. the climber has placed no protection and falls from 10 feet above the belayer to 10 feet below--a factor 2 fall) than if it occurs 100 feet above the belayer (a fall factor of 0.2), in which case the stretch of the rope more effectively cushions the fall.

Once the leader reaches a suitable spot for anchoring, or runs out of protection (hopefully the former), two things can occur:

1. The climber is lowered to the ground by the belayer or rappels to the ground, removing the pieces of protection on the way down. This is common when sport climbing or climbing short routes.
2. The leader belays the lower climber (the former belayer) up to the anchors. On the way up, the climber cleans (removes) the protection placed by the leader. This is common when climbing multi-pitch routes, where this process is repeated once for each pitch.

Sport climbing generally uses pre-placed protection, while removable protection is more commonly used when traditional climbing. However, it is not uncommon to see routes with both types of protection present when lead climbing.

Lead climbing is done for several reasons. Often, placing a top-rope is not an option because the anchors are not accessible by any means other than climbing. Sport climbing and traditional climbing both utilize lead climbing techniques for practical reasons, as well as stylistic reasons. Climbers may work individual pitches on top-rope, but valid ascents require the climber to lead the pitch.

Types of rock climbing


Rock climbing may be divided into two broad categories: free climbing and aid climbing.

* Free climbing requires the climber use only his/her bodily strength for upward progress. Commonly confused with "free-soloing" which means to climb without a rope. The essence of free climbing is that, although gear may be used to protect a climber in the event of a fall, the actual "climbing" is being done without the help of any artificial device.

* Aid climbing involves using artificial devices placed in the rock to support all or part of the climber's body weight, and is normally practiced on rock formations that lack the necessary natural features suitable for free climbing.

Other kinds of climbing:

* Lead climbing is a method of climbing in which the climber (here called the "leader") climbs a route from the ground up. To protect him/herself, the climber trails a rope which is managed by a belayer who remains on the ground or at an established anchor. As the leader climbs, he/she can either clip the trailed rope through pieces of traditional gear (cams, stoppers), placed in cracks, or clip the rope through gear already in place (bolts, pitons). If a climber falls while leading, he/she cannot comfortably sit back on the rope and be held by the belayer as in toproping (where the rope is anchored above the climber); rather, the leader will fall twice the distance between his/her position and the most recent piece of protection (a cam, stopper, bolt, etc.) that he/she clipped the rope through (assuming this piece of protection holds).
* Traditional Climbing, or "Trad" Climbing. In Trad Climbing, the leader uses mostly removable gear (and the occasional bolt placed on lead) to protect against falls. As in all forms of lead climbing, the climbing team (a leader and follower, or multiple followers) begins at the bottom of a climb and ascends to the top, the leader placing protective devices in the rock as he/she climbs. Once the leader is finished climbing, he/she establishes a belay. The follower then "follows" the route and removes all of the gear placed by the leader. It is important that the leader be proficient at placing Trad (or clean) gear (cams, stoppers, hexes, tri-cams, etc.) because his/her safety depends upon the soundness of each individual gear placement. Placing trad gear on lead can be time-consuming and thus tiring, sometimes making routes feel harder than their rating. Trad climbing is generally practiced according to ethical principles, that dictate only natural gear placements be made. These same ethical principles have driven many to put their lives in danger rather than place a bolt. If the climbers are exceptionally traditional, the leader will immediately lower to the ground or anchor after a fall (rather than continuing on from where he/she is hanging). It is, with perhaps the exception of Free-soloing, the purest form of climbing. A true traditional ascent will leave no trace of its passage.
* Sport Climbing is a type of lead climbing which involves the use of pre-placed permanent bolts for protection. This frees the leader from the need to carry and place traditional gear. The leader merely clips one side of a quickdraw (two carabiners connected by a loop of webbing) into a bolt and the other into the rope. A typical sport route will require the leader to carry between 6 and 12 quickdraws or "draws," one for each bolt in the string of bolts that protect the route. Sport Climbing, in essence, is focused more on the gymnastic aspects of climbing than the aesthetics or adventure. Sport routes are bolted with safety in mind and also because they generally (though not always) ascend faces that are not protectable by any other practical mean. Bolts, however, are not foolproof. The same stringence concerning safety found in Trad. climbing should apply to Sport climbing as well. In the case of a fall, sport climbers often rest on the rope and begin from where they are hanging, called "hang-dogging." Hard sport climbs often require that the climber literally rehearse every single move several times before he/she can complete a clean ascent (without falls).
* Top Roping involves suspending a rope from an anchor located at the top of a short climb. The climber ties into one end of the rope and is belayed by his belayer who manages the other end of the rope. The belayer can belay either from the top or base of the route. This is distinct from Lead climbing where the climber is not safeguarded by a rope attached to an anchor situated at the top of the route.
* Bouldering may be described as climbing short, severe routes on boulders or small outcrops. While safety ropes from above are occasionally used, most boulderers feel that the most ethical form of protection is a bouldering mat or pad similar to those used by gymnasts. In addition, other climbers standing on the ground may "spot" the boulderer, to help safely guide his or her fall.
* Indoor climbing is a form of climbing that can involve bouldering, top roping, and leading in an indoor environment on wood or plastic holds. For most it will be the easiest way to begin the sport.
* Free solo climbing: Usually describes free climbing without a rope or other protective gear. Free solo climbing is distinguished from solo climbing where a climber progressing alone uses a rope and protection devices including a self belay system.
