Key takeaways
- The British trad grade has two parts: an adjectival grade and a technical grade.
- The adjectival grade (e.g., VS, HVS, E1, E2...) describes overall difficulty, seriousness, and danger.
- The technical grade (e.g., 4c, 5a, 6a) describes the single hardest move.
- Together they convey both move difficulty AND how committing/well-protected the route is.
What the British trad grade is
The British trad grade is a distinctive two-part system for grading traditional climbs in the UK, combining:
- An adjectival grade — overall difficulty, seriousness, and danger (Moderate, Difficult, Severe, Very Severe (VS), Hard Very Severe (HVS), then open-ended Extreme grades E1, E2, E3…).
- A technical grade — the single hardest move (e.g., 4a, 5b, 6a).
A route might be graded, for example, ‘E2 5c’.
How the two parts work together
The adjectival grade reflects the whole experience — how sustained, committing, and well- or poorly-protected the route is — while the technical grade pins down the hardest move. Comparing them reveals character: a high adjectival but low technical grade signals a bold, poorly-protected runout route, while the reverse suggests a safe but physically hard one.
A climber sees two routes: ‘E1 5b’ and ‘E3 5a’. Despite the easier hardest move on the second, the much higher adjectival grade (E3 vs E1) tells them it’s far more serious — likely bold and poorly protected — so they choose the safer E1 for the day.
Why Britain uses it
British trad climbing prizes the seriousness and danger of a route, not just physical difficulty. A single number like the YDS or French grade can’t distinguish a safe hard route from a dangerous runout one of equal physical difficulty — the two-part system captures that, central to the UK’s trad ethic.
The bottom line
The British trad grade is a two-part system — an adjectival grade for overall seriousness and danger, plus a technical grade for the hardest move — that together capture what a single number can't: whether a route is bold and runout or safe but physically hard. Comparing the two parts reveals a route's true character, reflecting the UK's adventurous, seriousness-focused trad ethic.
Frequently asked questions
What is the British trad grade?
The British trad grade is the UK's distinctive system for grading traditional climbs, made of two parts: an adjectival grade describing the route's overall difficulty, seriousness, and danger, and a technical grade describing the hardest individual move. A route might be graded, for example, 'E2 5c' — the E2 being the adjectival grade and the 5c the technical grade.
How do the two parts of the British grade work together?
The adjectival grade (running through Moderate, Difficult, Severe, Very Severe (VS), Hard Very Severe (HVS), and then the open-ended Extreme grades E1, E2, E3...) reflects the whole experience — how sustained, committing, and well- or poorly-protected the route is. The technical grade (like 4a, 5b, 6a) pins down the single hardest move. Comparing the two reveals character: a high adjectival but low technical grade signals a bold, poorly-protected route, while the reverse suggests a safe but physically hard one.
Why does Britain use this two-part system?
Because British trad climbing places great value on the seriousness and danger of a route, not just the physical difficulty of the moves. A single number (like the YDS or French grade) can't distinguish a safe, well-protected hard route from a dangerous, runout one of the same physical difficulty. The two-part system captures that crucial distinction, which is central to the UK's traditional, adventurous climbing ethic.
