Gastons, Guppy’s and Grades! No, we’re not talking about Disney villains, fish and school…⁠ Next up in our climbing jargon busting series is terms beginning with G! 

For all our climbing glossary published until now, head to our blog here. 

G is for…

GASTON

Imagine opening a pair of lift doors with your hands; this is the way to place your hands on the climbing holds when doing a gaston. Very tiring; hard to stay balanced. Can be required in shallow cracks where there is no chance of jamming or laybacking. Named after French climber Gaston Rébuffat.

GUPPY

The climber’s hand is turned sideways and grips a hold by cupping it with the little-finger side of the hand.

GRADE

How difficult it is to climb something (almost always disputed as all bodies are different!)

Watch out for the rest of our alphabet dropping soon.
