**Outdoor Climbing Grades:

Where Numbers, Sweat, and Rock Legends Collide**

You crush 6b in the gym like a rocket, you feel invincible. Then you show up at the crag, jump on a 5c… and end up crying over a mossy foothold. Welcome to the wonderful (and sometimes cruel) world of outdoor climbing grades.

But before you throw your climbing shoes into the nearest bush, let’s take a moment to understand what these mysterious numbers mean, where they come from, and why they spark endless debates at the crag café.

**A bit of history:

When climbers started counting**

Grades were born from a simple need: knowing what you’re getting into before hanging 20 meters above the ground. But their history is anything but straightforward.

1930s: The Germans invent the UIAA system (I to XII), used for big alpine routes. Efficient, sober… a bit austere.

Fontainebleau, 1940–50s: Pierre Allain and friends start grading boulders. No crashpads, just courage and ankles made of reinforced concrete.

1980s: Patrick Edlinger climbs shirtless, hair blowing in the wind, inspiring an entire generation. He sends 8a the way others flip burgers.

Then come the extreme grades: 9a, 9b, 9c… with climbers like Fred Rouhling, Chris Sharma, and Adam Ondra pushing the limits of what’s possible — and sometimes, what’s believable.

How it works (or doesn’t)

The grade of an outdoor route depends on several factors:

Technique: slab, overhang, cracks, microscopic footholds that make you question your fingerprints.

Commitment: when the next bolt is 3 meters away and you start negotiating with the rock (“Come on, be nice…”).

Endurance: especially when the route is 35 meters long and you forgot your chalk.

Route reading: because outside, there are no fluorescent red holds telling you where to go.

And above all, it’s subjective. A 6c might feel easier than a 6a depending on your height, style, mood, or how many croissants you had for breakfast.

🤯 Juicy anecdotes from legendary climbers

Fred Rouhling creates Akira (9b) in 1995. A route so futuristic some people thought it didn’t exist. Spoiler: it does. And it hurts.

Chris Sharma, the surfer‑monk of climbing, refused for years to grade his routes. For him, “grades are like Wi‑Fi at the crag: not always useful.” He opens Realization in Céüse, the first confirmed 9a+. And the wet dream of thousands of climbers.

Adam Ondra, Czech extraterrestrial, climbs Silence (9c) in Norway. A route so hard even the holds needed a break.

Gym vs. Crag: two different planets

In the gym:

• Holds are clean, colorful, sometimes shaped like bananas.

• You can fall without getting hurt (except your ego).

• People clap when you stick a dyno.

Outside:

• Holds are polished, hidden, or covered in moss.

• You might fall onto a bush, a goat, or your belayer.

• It’s just you, the rock, and that cursed grade.

**Mini climber glossary

(to shine at the base of the cliff)**

Send: Climb a route bottom to top without falling. The climber’s holy grail.

Flash: Do a route first try with beta. Kind of like cheating… but legally.

Onsight: First try, no info. Just you, the rock, and your instincts.

Redpoint: Send after working the route, rehearsing moves, and whispering insults at the rock.

Crux: The hardest move. The one that makes you ask “Why am I doing this?” every attempt.

Zipper: Foot slips off a hold. Usually followed by a scream, a fall, and a dirty look at your shoes. (It’s always the gear’s fault.)

Clip: Put the rope into a quickdraw. Simple in theory, terrifying when you’re pumped 20 meters up.

Rest: A spot where you can breathe. Sometimes it’s just a tiny nubbin for your big toe.

Polished: A hold used so much it’s as slippery as a bar of soap. Classic in popular sectors.

Dyno: A dynamic jump to a hold. Looks amazing when it works. Looks tragic when it doesn’t.

💬 **The eternal debate:

“Underrated!” or “Am I just bad?”**

Grade debates are part of climbing folklore. Some crags are known for being “soft,” others for being “sadistic.” But in the end, a grade is a suggestion, not a truth carved in granite.

As an old climber in Annot once said:

“Grades are like wine: don’t trust them too much, but they make great conversation.”

🎒 In short: climb, laugh, forget the number

Grades are there to guide you, not judge you. They give you an idea, but your experience is what matters.

So climb, fall, laugh, try again. And remember: even pros struggle on a polished 6a.

And if you really want to shine, invent your own grade:

“It’s an emotional 7b, with a psychological crux and a philosophical finish.”
