Unraveling the MTB Trail Grading System: Choosing the Right Adventure for Your Ride

Not all trails are created equal. Whether you're a beginner looking for a leisurely ride or an expert seeking a challenge, understanding the trail grading system is crucial. Let's delve into the world of MTB trail grades and explore the factors that determine each difficulty level.

Although these are the official grade systems, from personal experience they are just a guide. One trail centres red may be very different to the red of a bike park like DYFI.

Always pre ride the trails first and scope out any features, re ride it, now you know it hit it hard! and enjoy!

Exploring the Basics of MTB Trail Grading

Mountain biking trail grades serve as a universal language for riders to assess the difficulty of a trail.

For UK riders the existing system, prominently used by Forestry and Land Scotland, categorizes trails into Green (Easy), Blue (Moderate), Red (Difficult), Black (Severe), and Orange (Extreme). Each grade is tailored to specific skill sets and biking capabilities.

You may not see this as often now, as the grading system was updated to Green (Easy), Blue (Moderate), Red (Difficult), Single Black (Severe), and Double Black (Extreme).

Deciphering Trail Colours: What Each Signifies

Understanding the colour-coded difficulty levels is crucial for selecting the right trail for your skill.

In the UK I would look at it like this.

Green - Beginner trail, no features (Jumps, Drops, Rocks etc) suitable for anyone that can ride a bike.

Blue - Intermediate, flowy trails, some small features like rocks and roots. Suitable for people dipping their toes into the world of mountain biking.

Red - Proficient riders only. Steeper trails with more features. Possible small/medium steps/drops. Could include small table jumps, berms are a must! Everything will likely be rollable. Its time to move fast.

Black - You will need a quality bike for these trails and some expert skills. Expect steep downhills, varying terrain unavoidable drops, rock rolls and gap jumps.

Double Black -  Consider yourself a pro level rider? Expect everything from a black but harder. Bigger jumps so jumping skill is a must, steeper downhill sections with corners etc thrown into the mix. Demanding trails for any rider.

Triple Black - Ridiculously steep, off camber, crazy moon booter jumps and very challenging at every section. Only take this on if you are and expert.

Trail Grading from Across the Globe

MTB Trail Grading System - British Cycling

The British Cycling MTB Trail Grading System emphasizes the suitability of trails based on cyclist proficiency. From Blue - Moderate for intermediate riders to Black - Expert mountain bike users, used to physically demanding routes. Quality off-road mountain bikes. 

Although this is the British Cycling grading system, I would suggest from personal experience the Forestry and Land Scotland's grading is more accurate for most UK riding.

What to expect from a Triple Black at DYFI bikepark


Embarking on a mountain biking adventure requires a thorough understanding of trail grading systems.

From the classic Green to the challenging Double Black, each trail grade offers a unique experience.

Riders should choose trails aligned with their skill levels, ensuring a safe and enjoyable ride. One persons idea of fun is another persons idea of craziness. So ride what you enjoy.

Also if you're a cross country rider you probably dont need to be doing a double black at bike parks, so again align your planned trips with the category or riding you prefer.
