Dulux London Revolution Trails routes



13.7 miles along the iconic Thames Path.

Start Location: Marlow
Finish Location: Windsor Festival Finish
Distance: 13.7 miles
Elevation Gain: 47m
Stops on route: 3


Starting at Marlow Rugby Club, you will accompany the river’s twists and turns for most of the race. Boasting over 120 species of fish, the home of multiple water mammals and the grounds for countless species of bird, the Thames is rich not only in wildlife but also in history.

The longest river in England, it provides two-thirds of London’s drinking water and is referenced in text all the way back to 54 BC by none other than Julius Caesar!

Hitting the village of Cookham early on in the route, make sure you take the time to appreciate the quaintness of this idyllic village before heading out to re-join the Thames Path.

As you head downstream, look to the right for Bray’s ‘Millionaire’s Row’ on the opposite side of the river with tall lavish properties sure to wow everyone who treks past.

For all the rowing fans out on the trails, you will know exactly where you are when you spy Dorney Lake through the hedgerow on your left. Famed for hosting a total of 30 medal events in the 2012 Olympic Games, it is renowned for being one of the most successful venues in history for our beloved Team GB.

Looping back over the river, you will push on to receive your own medal as you trek through to our festival finish line at Windsor Racecourse where an ice cold beer will be waiting for you along with numerous other activities.


27 miles exploring the idyllic English countryside.

Start Location: Marlow
Finish Location: Windsor Festival Finish
Distance: 27 miles
Elevation Gain: 312m
Stops on route: 5


Setting off from Marlow Rugby Club, the route heads along the riverbank where you can admire the stunning riverside estates, one of which is the famed Macdonald Compleat Angler hotel. Built in the 1640’s, it was frequented by the likes of F. Scott Fitzgerald, T.S. Elliot and even Queen Elizabeth who is known to have visited for the idyllic views.

Bearing towards the quaint village of Hambleden, you will spy the brick and flint stone houses. Often used in film sets for it’s charming personality, it has featured in the likes of Midsomer Murders and the award winning Band of Brothers. Heading back to Marlow, you will twist and turn your way along the Thames Path, sticking with the river for most of the remaining journey. On the way, be sure to look out for river dwellers such as the hard to spot water vole or even the seals that are rumoured to make an appearance now and then!

Powering on to the last stretch of the trail, you will take the final turn in to the Windsor festival finish where your friends and family will be waiting for you to celebrate. With yoga classes to help stretch out any aches and pains, live music and ice cold beer, there is nothing more you could want from a finish line!


32.2 miles through leafy woodland, rolling hills and the famed Thames riverside.

Start Location: Marlow
Finish Location: Windsor Festival Finish
Distance: 32.2 miles
Elevation Gain: 505m
Stops on route: 6


Your journey will start at Marlow Rugby Club heading along the idyllic riverside past the town’s famous iron suspension bridge before diving into the depths of the woodland. Passing through Hambleden village, the Chilterns await where you will start to notice the steepness of ground below. Despite the challenging climbs, make sure you take the time to look skyward to spy a famed Red Kite flying high overhead, spurring you onward.

Looping back towards Marlow, the journey becomes easier underfoot as the trail descends to the gravelly welcome of the Thames Path. From boats and canoes to otters and water voles, the waterway is always full of life, so keep an eye out to see what you can spot as you journey West.

Passing Dorney Lake on your left, you may see rowers out on the stretch of water where Team GB claimed a total of 12 medals in the 2012 Olympic Games. Crossing back over the river and making your way on to the last stretch of the trail, excitement is in the air as the finish line comes into sight with our festival village waiting for your arrival. Grab a drink, visit our food trucks or lounge in a beanbag listening to live music as you relax and celebrate your achievement.

Age Limits:

Participants must be aged 16 years or above by the start of the event to be allowed to enter.

Participants under the age of 18 years (but over the age of 16 years) must be accompanied by a parent or guardian for health and safety reasons.

Team Entry:

Teams of friends: as we need all medical and dietary info from each participant we need each individual to register individually. There will be a section on the registration form that allows you to write in your team name, so that we can link you with your other team mates. This is important so that we know to put you in the same camping zone for the event.

Corporate teams: if you are interested in entering a corporate team, please contact us at [email protected] We can invoice your company for the places so the individuals don’t have to pay on registration when signing up. We will also let you know how we can support your pre-event experience on elements such as kit design and training days.

Race Pack:

Your race pack will be sent out in the post around 2 weeks prior to the event start date.

If you are travelling from overseas, you will not receive your pack in the post and you will need to pick it up from the registration desk on the day. This is also the case for anyone who registers after 10/04/2020.

The race pack will include your bib number with safety pins, a luggage label, your participant wristband and your parking (if you booked parking before the deadline above). If you booked parking after this deadline, it will arrive separately in the post the week of the event.

Your merchandise is handled by a separate supplier, so it will not arrive with your race pack.

If you have any questions about your pack, please head to the Info Desk on the day of the event.

Start Times:

We will be running a staggered start to reduce congestion on the first part of the route. You will have chosen your start time when registering for the event.

The start times for the Saturday morning are:

08:30am-9:30am: Ultra marathon and Marathon waves
12:00pm: Half Marathon

We recommend you arrive 30-45mins before you start time.

You are able to change start wave up until one month before the event. This needs to be a request sent by email.


We will be awarding prizes for the fastest male and female for each distance.

These prizes will be awarded on gun times, not chip times. This is so we can award the prizes at the finish line on the day of the event.

We have designated competition waves as follows:

Ultra Marathon & Marathon: 9:15am
Half Marathon: 12:00pm
Please note: these waves are not exclusive to people competing so if you are, then we recommend you get into the start pen as early as possible.

Kit List
There is no such thing as bad weather, just inappropriate clothing. There is nowhere where this rings truer than England so you need to be prepared for anything from hot sun to torrential rain.

We will send a kit list before the event with more detailed guidance but basic kit should consist of: trail trainers/boots, socks, a short and long sleeve breathable sport top, a waterproof shell jacket, sun hat, woolly hat, gloves.

We provide transport for a bag to the finish line, so you don’t need to carry too much.

Spectators are welcome! Your friends and family are welcome to come and see you along the route, but we ask that they avoid pit-stops as these areas are for participants only. A more specific breakdown of the route will be published closer to the event.


How do I transport my bags from the start to the finish?

We will transport your bags for you from the start to your final destination each day. In your registration pack you will be given a luggage label with your participant number on it to attach to any luggage so it is easy to find at the end of the day. You’ll just need to drop bags with us in the morning and it will be there for you to pick them up at the other end.

Is the route fully signed?

Yes, the route will be fully signed.

How much training do I need to do?

This is dependent on how much exercise you do currently. We provide you with comprehensive training plans for all distances for both running and walking,

You will also be provided with training advice to ensure you are in the best possible shape. Other than that we recommend regular, consistent training – give yourself enough weeks to train but don’t overdo it!

Will there be live tracking?

In partnership with Open Tracking, you can now hire a GPS tracker for the duration of the event!

Your tracker will provide accurate location data, available online for your friends and family to view, so they can see how well you’re progressing along the route. This is NOT linked to your event timing but it does mean your supporters can see more accurately where you are throughout the event and how close you are to the finish line!

Can I bring my dog?

Dogs (aside from assistance dogs) are not permitted on the route as part of the event, due to the volume of people on the trail and the challenging nature of the course. Participants will do a lot of training in the run up to the event, and we cannot ensure that dogs have the stamina to complete the route or be responsible for them.

Dogs are only allowed on certain basecamps due to the health and safety regulations on the farms, so please email us directly if you would like to find out which basecamps they will be able to visit.

  • Did the Ultra Marathon in 2019

    Having completed and enjoyed the Threshold Treble in 2018, I decided to give their latest trail run a try and was really glad I did!
    The run starts at the Marlow Rugby Club and then takes you on a loop through the challenging but stunning Chilterns for the first part of the run. After looping back to Marlow you follow the Thames Towpath down to the Windsor Race Course.
    Based on their previous runs, I had high expectations of the checkpoints and they did not fail to deliver. The volunteers were all very supportive and helpful. The finish at the Windsor Race Course brought together both the runners and cyclists (from the cycling event) and there was lots to keep everyone entertained, fed and watered. The weather certainly played it's part but would definitely recommend this as first Ultra option if you're worried about going over the marathon distance.
