Riding the Iron Duke

The Kinesis UK Iron Duke takes you through the heart of a landscape that spans the ages! From the historical town of Marlborough, ride up into hills littered with historic sites, including the Iron Age hill fort at Barbury Castle, and through the ancient Savernake Forest, owned and managed by the same family since the Norman Conquest and home to trees up to and over 1,000 years in age.

From St Johns College on the edge of town, you will ride into Savernake to explore the maze of Forest trails, before tracking the beautiful Kennet Valley to cross the river and ride up into Marlborough Downs, and onto the magnificent Ridgeway. After your excursion into the hills, there’s a long flowing descent back down to the valley, and a last blast through the West Wood before you return to the finish.

This a ride with an epic feel – broad, open countryside with sweeping views and long, rolling trails to enjoy. The combination of open hill, riverside and forest trails adds variety to the ride and showcases the beauty of this corner of the country! Every mile of hte Iron Duke is well worth the effort!

Event Logistics

On the Ride

Once you’re ready to start, report to the start / finish area with your timing chap strapped to your ankle. Listen to the short briefing and ride across the timing mat as directed. As you go around the route, you will find bright orange signs and ribbons to follow. At route divide points, you will find yellow signs showing you which way to go to follow the Full, Mid or Short routes. These should guide you around the whole route, but use your map if you think you have strayed off course or have a problem with the route navigation. There are also emergency contact numbers on the edge of your map. Ride safely at all times, and remember that you are on public rights of way and roads. This is not a race, so please ride appropriately, and be friendly and polite to other trail users you meet. At the end of the ride, pass over the timing mat once again, and hand in your timing chip. For those interested in there ride time, these will be available on the computer screen at the finish.

Entry on the Day

You can enter the event on the day, although there is a small surcharge of £3 (so pre entering is recommended). Just arrive before the end of the registration period and pay at the desk.


Go to the registration desk on your arrival. If you’ve pre-entered via the internet or posted your entry, you’ll have a timing chip on an ankle strap to collect at the desk. If you haven’t pre-entered, pay at the desk and a chip will be allocated to you. Collect your colour A4 map at registration also. Next, get yourself ready to ride.

Following the Route

At route divide points, you will see a set of yellow signs, with “Full Route”, “Mid Route” or “Short Route” written on them, pointing in different directions. At this point, follow the right sign for the route you are riding. Once you get beyond the route divide point, you will start following orange signs and ribbons again.

(Please note, in spite of our best efforts, signs can go missing or be tampered with during the course of the day. Make sure you pick up a copy of the route map at event registration, and carry it with you for use if needed.
