The Slate Trail

From quarry to summit.

The Slate Trail is a self-guided gravel route through the raw, industrial landscapes of Snowdonia — linking forgotten quarry tracks, quiet mountain roads, and remote lakes that most riders will never see.

Long Course

90km of riding.
2100m of climbing.

Short Course

74km of riding.
1446m of climbing.

No shortcuts.

Ride by GPX as you move through hardpack, loose slate, and silent backroads carved into the hills.

No race numbers. No noise.

Just distance, elevation, and space to ride.

Designed to be ridden, not rushed.

At the finish, a locally crafted slate medal from the actual slate you were riding on — simple, heavy, and earned.

What you get for your money:

• An incredible, carefully planned route with accurate GPS
• A relaxed, friendly atmosphere with like-minded riders
• A chance to explore an area many won’t have ridden before
• A shorter route option (being added this week for those not taking on the full 90km)
• A proper feed station — homemade food, well stocked, and a highlight of all our MTB events
• A unique finishers medal made from the very slate you’ll be riding on

We believe the entry fee offers strong value for the experience. Events like this take a huge amount of time, planning, and behind-the-scenes work to deliver safely and properly.
