CX Century: The South Downs Way, 6th July 2019

100 mile or 100km CX Challenges

The South Downs Way; it has long been a right of passage in mountain biking circles. And now this hundred mile ribbon of imposing chalk downland is about to become an icon of the CX/gravel scene.

Renowned as a supreme physical rather than technical challenge, the South Downs Way is the most high profile answer to the long distance US gravel scene that we have. But so much more, too. The huge climbs and sweeping descents wouldn’t be out of place among the Tuscan Strade Bianchi, while the expansive coastal views are quintessential British beauty.

CX Century brings you all of this in the ultimate gravel event! An unforgettable experience and a monumental challenge that will prove your place amongst the endurance elite! CX Century will be a badge of honour and pride, and this is your chance to be one of the very first to join that club!

CX Century is fully supported, from route marking to multiple feed and support stops, we make it possible for you take on this epic ride as part of the first mass CX/gravel bike challenge!

You can also enter on an MTB – read more here:


ALSO INCLUDES: 100km option.

CX Century also includes a kilometre century option; 100km and almost 7,500ft of climbing in a single day, 90% off road on CX friendly chalk tracks, the CX Century kilometre century is a physical test and a genuine epic, and the perfect preparation for taking on the full 100 mile CX Century in a future year!

Starting alongside the 100 mile event in Winchester, the 100km route finishes on top of Truleigh Hill above Shoreham; ideal for an easy pick up off the A27, or downhill all the way to the station to begin your journey home!

Transport Options

You will need to arrange transport to and from the event. Due to the numbers of riders and the broad timescale and distances the event will cover, we cannot offer transport solutions as part of the event. you will need to make your own way to the start, and arrange either a pick up or transport solution from the finish. Prior to the event, we will provide you with as much information as you need to help you make all of your arrangements in good time, including pick up locations, connecting train services and local taxi contacts. For the second half of the route, the South Downs Way runs close to the south coast mainline, so you are never too far away from a station (and downhill all the way!)

Cut off & bail out points

Your big target for CX Century is to complete the challenge. Not everybody will finish, by any means. There will be cut off times at strategic checkpoints on the route, after which riders will not be allowed to continue on the event. Should you miss a cut off or decide to abandon the ride, we will provide you with detailed options for your transport options from those cut off / bail out points, including location details for pick up, nearest rail station and local taxi numbers.

Event support vehicles & mechanical assistance

Our support vehicles will be travelling along the route on the closest possible roads, and will be equipped to help with mechanical problems and basic first aid. However, please note that getting assistance to any point on the South Downs Way may involve considerable distances and can take a long time. Riders will be expected to carry basic tools and spares, and a small, basic first aid pack. Your first and best option is always to fix yourself if you can; if you can’t we’ll be there to help.

Luggage transport

We will be able to carry a small amount of luggage for you along the route (such as a small overnight bag with change of kit etc). This will be transported from the start in Winchester to the Truleigh Hill checkpoint (and 100km finish) where it will be available for you to access. From here, luggage for riders on the 100 mile course will be transported to the finish at Beachy Head.

Please note: we will take care of any luggage left with us, but cannot take responsibility for any damage or loss that might occur. Any luggage not claimed at the ride finish will be taken back to our offices after the event, from where it can be returned to the owner at the owners expense.

Friends and family support vehicles

A good number of riders will arrange for friends or family to support them along the route from their own vehicles, and to collect them at the end of the day. We welcome friends and family support vehicles on the event, however, we will need them to to observe our guidelines to help the event to run smoothly. We will provide details of recommended rendezvous points on the course, with suitable access and parking. There will also be certain roads on the course where we will ask vehicles not to attempt to access the course, due to road width or parking limitations. This information will be provided to you well in advance to allow you to plan.
