OVERVIEW

Close to London but far off the beaten track, the Chilterns Gravel X takes in parts of the famous Ridgeway and the glorious hills in the heart of this region.

 

Nearly all of the route is off road or on quiet back roads including some secret local spots & a few climbs both on tarmac and gravel. A cracking summer gravel day out!

RIDE HIGHLIGHTS:

What to expect

If you’ve not ridden in the Chilterns before, you are in for a treat. You will ride on a mix of quiet backroads, plenty of smooth gravel amongst some chunkier stuff. There is plenty of climbing and most of these short & fairly steep.

Ride difficulty

There isn’t much flat on the route. On the long ride there are 9 significant climbs, 5 on gravel, 4 on tarmac. This ride is suitable for most riders but 1,300m of elevation on a ride with little flat will feel like a tough day.

Long Route ****

Medium Route ***

*****  Reserved just for our hardest routes. Expect long distance & lots of challenging climbs both on and off road. 

****  Typically longer rides with regular climbs which could be both steep & long. Suitable for regular riders with some training.

***  A mix of terrain & elevation. A decent day out with some tricky sections but still suitable for regular riders.

**  Some harder sections but suitable for all regular cyclists

Easy, suitable for all riders. Mostly flat route.

Technical difficulty

40% of the route is on tarmac (though it’s not always the smoothest on the quiet backr0ads). The off road is a mix of gravel, a few short sections of rockier terrain and some hard packed dirt trails which can be slippy if we get rain.

Long Route ***  

Medium Route ***

TYRE & BIKE RECOMMENDATIONS

This route is designed for gravel bikes but you will be fine on a hardtail MTB. We do send out tyre recommendations closer to the time. Unless it’s very wet, a standard gravel all-rounder tyre (35-45mm) will be ideal.

ROUTE DETAILS

LONG ROUTE

We start in Kingston Blount and get on The Ridgeway almost straight away and stay on this for almost 20km before heading into the heart of the Chilterns.

 

Over the next 40km we take in 7 climbs on a mix of tarmac and off road with some amazing views. The last 25km is quick on some less known gravel sections before we arrive back for a well earned beer & food.

 

The seven climbs come in all shapes and sizes, the rest of the ride is fairly fast so this is a big ride but suitable for anyone happy to get over some climbs.
