The adrenaline rush and all-over workout you get from rock climbing is as addictive as it sounds. And we love it.

To the uninitiated, the world of rock climbing grades can seem like an impossible jumble of letters and numbers. As a diverse and international sport, climbing has – rather unhelpfully – developed an equally diverse and international set of alternative grading systems.

But don’t be put off if you don’t know your Font scale from your French grades – it’s time to decipher them. Because whether you plan on scaling a climbing wall or rock face, you’ll have far more fun having chosen a route that suits your experience and ability.

So, rope up and enjoy the buzz!
