Darkside Running is proud to introduce two new winter ultra marathons to the UK endurance racing calendar.  Starting at sunset and running through the night, our races follow the Norfolk Coast Path, passing through the Norfolk Coast Area of Outstanding Natural Beauty (AONB).

December 14-15, 2019

Sunrise: 83 miles from Snettisham, Norfolk

Half Sunrise: 45 miles from Cley-next-the-sea, Norfolk

Both races finish at The Britannia Pier in Great Yarmouth, Norfolk and will be run under race permit 2642, granted by the TRA, following UKA rules for competition.

Sunrise Ultramarathons

About the races

The Norfolk Coast Path runs for 84 miles from Hunstanton to Hopton-on-Sea, travelling through the Norfolk Coast Area of Outstanding Natural Beauty (AONB).  A stunning journey in its own right but we have added a couple of twists.

Firstly this event will be run in mid-December.  While Norfolk may not seem that remote when the north winds blow it comes directly from the North Pole, and with the flat and open terrain, conditions could be challenging.  

Secondly, the events will be run during the hours of darkness.  As the sun sets in the west, you will be set off from the start in Snettisham.  How far can you get before the sun rises in the east at 07:58, some 16 hours and 19 minutes later?   For the speedier runners amongst you, can you reach the finish 83 miles away by The Britannia Pier in Great Yarmouth?

Support is provided along the route but is kept to a minimum, to minimise the environmental impact of the race, avoid disturbing locals sleeping in their beds and to add to the running adventure.  A full indoor checkpoint is provided at roughly halfway, in Cley-next-the-sea.  Here you will have access to a drop bag and also be provided with warm food and drink.   Additional mobile checkpoints will be provided along the route but these will be limited to water and some snacks, so pack accordingly.

For those that don’t fancy the full Sunrise experience, we will be offering the Half Sunrise.  This starts from the halfway checkpoint at Cley-next-the-sea at 22:00 and follows the same route to the finish in Great Yarmouth some 45 miles away. Both should be an exhilarating pre-Christmas challenge and a great way to end the year.

UTMB® and ITRA Qualifier Events

Both races have been awarded ITRA points, allowing you to use them as qualifying events for the 2020 UTMB® races.

GPS Tracking

All our athletes will be given a GPS tracker to carry during the race, for safety and also to allow your friends and family to follow your progress as you race the sun to the finish in Great Yarmouth

Regular Support

Regular support is provided along the route, with water stops and a half way checkpoint for those racing the Full Sunrise, where runners can access a drop bag and warm food and drinks

Bus Transport

Buses are provided if required to transport all racers from the finish at Great Yarmouth back to the start at Snettisham for the Full Sunrise or Cley-next-the-sea for the Half Sunrise. This is an option you can select at checkout.


We aim to minimise the use of plastic and other non-recyclable materials in our races. For example, race t-shirts will only be available as an additional purchase. Competitors will also be expected to carry their own reusable cup.

Giving Back

We are keen to support the local communities and environment that our races pass through. £1 from every entry will be donated to a coastal charity, along with 25% of all race profits.
Beautiful route following one of the newest UK national trails

The Route

Starting at sunset outside the Sailing Club at Snettisham, The Sunrise heads north towards Hunstanton. From here it turns eastwards, joining the Norfolk Coast Path, which it follows (with a few diversions for safety and environmental reasons) all the way to the finish 83 miles / 133 kilometres away, at Britannia Pier in Great Yarmouth.

The Half Sunrise starts in the pretty village of Cley-next-the-sea and follows the Norfolk Coast Path eastwards, also finishing at Britannia Pier in Great Yarmouth, covering a total distance of 45 miles / 72 kilometres.

Cley-next-the-sea also marks the only major checkpoint on the full Sunrise, where runners will be able to access a drop bag, take shelter and get warm food and drink. Additional checkpoints will be set up along the route (exact locations to be confirmed) but these will be outside and will only provide water and simple snacks.

Competitors are therefore expected to be self-sufficient for the majority of the race and pack accordingly for a winter ultra marathon.

Both events will be run under race permit 2642, granted by the TRA and will also run under UKA rules for competition.

Frequently Asked Questions


Is there a mandatory set kit list?

Yes, as you would expect for an ultra marathon running through the night in the middle of UK winter, for safety reasons there is a mandatory set of kit you are required to carry at all times. This will be checked at registration, with further random checks during and at the finish. Failure to produce items will result in disqualification. 

Full details on mandatory kit, can be found over on our Race Kit page.

Are there any entry requirements?

As per UKA rules for races of these distances, you must be a minimum of 20 years old on the date of the event.  We also expect that Half Sunrise entrants will have previously completed a trail marathon and Sunrise entrants will have previously completed an ultra marathon of around fifty miles.

Norfolk may seem like a calm and pretty place but in mid-winter, this can be quite exposed terrain, so train accordingly and familiarise yourself with running and navigating in the dark.

Read our full terms and conditions for further details on our entry requirements

What are the time limits / cut offs?

For the Sunrise you have until sunset at the finish to complete your journey, which is at 15:38 on Sunday 15th, or 23h 57m since the start. There is an enforced cut off at the major checkpoint at Cley (38 miles) of 03:00 Sunday, leaving you just 12h 38m to finish the final 45 miles.

For the Half Sunrise you have 12 hours to complete the 45 mile journey to Great Yarmouth, with the finish line closing at 10am on Sunday. There are no cut-offs along the route.

Is the course marked or is it a self-navigation event?

Both Darkside events are self-navigation events along a designated national trail.  

This means that aside from some markings we may add around the checkpoints, you will be required to navigate yourself using map, compass and the existing signposts and acorn markers positioned along the route.

While the signs are fairly well placed, familiarity with navigating in the dark using a map and compass is essential.

What food is available on the course?

A full menu will be published closer to the event itself but expect a small selection of cold simple sweet and savoury snacks at the checkpoints out on the course. For the full Sunrise, the halfway checkpoint at Cley will also provide soup, warm drinks and a vegetarian pasta dish.

What if I change my mind?

Details of our refund policy can be found in our terms and conditions but in short we are able to offer some sort of refund up to eight weeks before the race and transfer to another runner up to a week before.
