Grades

We want to work with the rock climbing community to get a comprehensive and intuitive coverage of grades in the system. This is a long term initiative and at times will involve fundamental changes to the way grades work on the site. We welcome feedback on grades, but for this to be useful to the community as a whole it has to go onto our GithubBugs and new features issues list. We don't promise to fix things straight away, but we will link the discussion into this article so that the whole community can constructively contribute.

Grade conversions ↑ Back to contents

theCrag can automatically convert grades to a different system according to the table below. If you can suggest a better translation please log an issue in GithubIssues list

Note the coloured Grade bands which are used throughout the site as a quick way to gauge the general level of difficulty of a route or area.

Internally grade conversions work through an open ended fine-grained internal system, currently with over 500 grade levels.

If you would like programatic access to the grades and grade conversions through the Sharing and embeding (API). The programatic version of this table is available through the following API call:

http://www.thecrag.com/api/config/grade/system

Grade bands ↑ Back to contents

theCrag has segmented climb difficulty into 5 broad categories - Beginner, Intermediate, Experienced, Expert and Elite. These definitions are somewhat arbitrary, but they are based on many years of climbing experience and has some statistical basis.

There are two common area difficulty graphs used throughout the site, the grade band and dual grade band.

The grade band chart shows the relative number of climbs at the particular difficuly bands. This is shown at each area and should give you a quick summary of the area's relative difficulty.

The dual grade band shows also what grades people are climbing at an area, based on the number of ascents at each grade. Some areas may have a lot of hard climbs, but the easier climbs are climbed more often (eg Arapiles) and other areas have a lot of easier climbs, but people go there for the hard climbs (eg Grampians).

The table below fives a brief description of each band.

Beginner The level of difficulty for your first couple of days of climbing (seconding or top roping). Many people may achieve these grades on their first day of climbing. There are still some very scary and/or dangerous climbs at this level (eg Bard).
Intermediate Typical grades for people with less than a years climbing. Note that most people cannot climb this level on their first couple of days of climbing. Statistically speaking, most outdoor climbing is done in this band. A lot of experienced climbers end up backing off to this level as they enjoy their climbing into old age.
Experienced People can achieve these levels if they have been climbing fairly regularily for a couple of years. These grades are where the social climbers start becoming rare.
Expert You really need to be training in a focused way to climb at this level. Not so many people reach this level.
Elite You climb for a living, are sponsored and have a full time trainer and massuer looking after you. This is the best of the best. If you are normal, you would not have a hope of even dogging up one of these climbs.

How are grades assigned to routes? ↑ Back to contents

Routes have a registered community grade and a list of independent user and publisher grade contributions. The user and publisher grade contributions are displayed on the route page. The official grade of the route according to theCrag is given by the registered grade.

Please consider the registered community grade as the grade that has been accepted by the community. This may change over time.

Registered community grade ↑ Back to contents

The registered community grade is the official grade of the route, and is used through out the website and publications.

A registered community grade may have multiple components, for example:

  • A free climbing grade (5.12a) and an aid grade (A3), combined would read 5.12a A3.
  • British technical (4a) and adjectival (MS), combined would read MS 4a.

A route may have official grades from several different grading systems (eg in Thailand many routes have an official French and Australian grade). For example:

https://www.thecrag.com/climbing/thailand/krabi/route/17710201

The above route, 'Knights In White Satin' has a registered grade of 7b+ French and 26 Australian Ewbanks. Because the Thailand is assigned the French context the French grade will be shown on the site.

Once a route has a registered grade it can only be changed by an Editor and is not affected by subsequent user contributions.

Grade contributions ↑ Back to contents

Anybody may make a grade contribution. A climb may have several grade contributions from users and publishers.

When you add a new route, the grade you enter becomes your grade contribution (unless you are citing a publication, in which case in becomes a publisher contribution). For new routes your grade contribution also becomes the registered grade.

You may add your user grade contribution to an existing route using the update route details process. If the route already has a registered grade then this will not be effected (otherwise your contribution is used to start the registered grade).

Grade ranges ↑ Back to contents

Behind the scenes everything is a grade range with a minimum grade and maximum grade. Mostly people will use just one grade, but on occasions it is useful to use a grade range for a particular route (eg you may input 5.10a-b, which will be interpreted by the system as a grade range and displayed as 5.10a to 5.10b.

Grade ranges are absolutely necessary for grade conversions. Very few grade conversions match exactly there is usually overlap. For example 5.8 in the Yosemite Decimal System maps to both 15 and 16 in the Australian Ewbanks system.

Aid eliminates ↑ Back to contents

A route may orinally be a 5.10b A4, then later somebody may climb it as a 5.11a A0, then later as a 5.12c. In this scenario the route should have the cleanest grade as its registered grade, but may have all the other grades listed as grade contributions.

Note we have plans to make some changes here to cater for multiple whole grades, so all aid eliminates can be created as alternate registered grades and available for selection when ticking.

Special rating systems ↑ Back to contents

You may use the YDS protection rating in your grade contribution or registered grade. For example 5.10d X.

On some pages the system does not display the mild ratings to avoid clutter.

Although not part of the registered grade you can include some additional rating systems in your grade contributions. These include:

  • Stars

If you add a , or to the end of your grade contribution the system will recognise this a star rating. See How stars work.

How are grades assigned to ascents? ↑ Back to contents

Currently when you log an ascent the asent will automatically take up to two of route's registered grade components as the ascent grade. If there are two grade components (eg British Adjectival and Technical or Free and Aid) then both will be catered for. If there are more than two (eg Free, Aid and Protection), then one will be dropped.

A logged ascent has a primary grade and secondary grade independent of the route's grade. This means you may update your ascent to any grade you want, such as a different grading system or different grade to the route.

To adjust your ascent's grade after you have logged the ascent follow the following procedure:

  • Log in to theCrag.
  • Go to your dashboard page.
  • In the Logbook top level tab navigation click 'All your ascents' dropdown.
  • Look for the ascent you want to update. There is a down arrow on the right, click it then click the 'Edit' dropdown.
  • Select the new grades.

Note that ascent logging grades is a little restrictive and we plan to bring this in-line with the full route grade capability.

The minimum level of difficulty of the ascent grade and the route grade is used for Climber Performance Rating (CPR).

Grade contexts ↑ Back to contents

Our aim is for you to contribute grades as you see them in guidebooks and for the platform to be smart enough to work out what you mean.

Grade context meaning ↑ Back to contents

What does it mean if you type in the grade '5c'? If you were in Britian you would think it was the Experienced British grade 5c, but if you were in France you would think it was the Intermediate French grade 5c. If it was a bouldering route in Fontainebleau then you would think it is the Experienced Fontainebleau bouldering grade 5C. Interpretation of grades is dependent on where you are and the style of route, this is what we term grade context.

A Grade context is a way of the platform working out how to interpret potentially conficting grades written in plain text, and we set a grade context at the country level.

A grade context is simply a priority list of which grade systems it should check first when matching a grade. For instance in Australia, you can use a french grade, but it will check it first against the locally used Ewbank, and V-Grade bouldering grade systems first, and then if it doesn't match it will check against all the other grade systems. The platform defines as few contexts as possible in order to eliminate conflicts. In general most countries can use the default context.

You may set the default context for any area which overrides the inherited area above. You may also set the context on a route.

Currently the system defines the following contexts:

Examples ↑ Back to contents

The best way to explain how the system converts the plain text you enter into grades is to look at some examples.

(If you see a way of writing a grade in a guidebook then test it out and if it does not work then please contact us so we can enhance the system.)

Context Style Text entered Grade Comment
US Trad 5.12a
US Trad 5.12 The system has a grade system where grades are expressed as 5.12-, 5.12 and 5.12+.
US Trad 5.12+
US Trad 5.12a+ Note that + does not always form part of the offial grade, in which case it is ignored.
US Trad 12a The system is able to work out common partial grades.
US Trad 12 partial grades can be very dependent on the context (in US context this is 5.12, in AU context this is 12).
AU Trad 12 Compare to above example
US Trad 5.12a-5.12c This is interpreted as a grade range.
US Trad 5.12a-b Common abbreviated grade ranges
US Trad 5.12a/b The forward slash '/' is interpreted as an or, in which case the system assigns the highest single grade.
AU Trad 17/18

Grades in a gym ↑ Back to contents

Because indoor climbing is not standarised, gyms can opt for their own color codes. See the for more information about setting up gyms on theCrag.

For gyms, theCrag color scheme does not apply to routes in the crag, but rather the color specified against that route.

Country context's ↑ Back to contents

Default contexts are set at the country level but can be overriden at any area below the country. For example Germany has a UIAA context, but there are plenty of crags which override to a Saxon (SX) context. The following table shows the current system settings for country context.
