The Course

We always look forward to working with Anglian Water for our Grafham Water Swimrun event. We have undulating 5k, 10k and 21k courses and super open water swimming. The course has easy entry and exits into the water and amazing trail running through the woods and tracks around the reservoir. The courses head out along the north shore, with swims across the natural bays, runs through woods and around the reed banks. The  shorter courses then weave their way back along the north shore to the finish as the 21k heads off through the nature reserve and around the reservoir.

Rules & Terms and Conditions 

Registration and Race Briefing:

All participants must register at Event Registration as directed in the Race Handbook or as communicated via email.

At registration you will collect your swim hat and number band.

All participants must attend the race briefing. Participants that do not attend the race briefing will not be allowed onto the course to compete. 

Mandatory Equipment:

You must carry any equipment you require for the event from start to finish. You will not be eligible for any prizes if you fail to carry all your equipment from start to finish.

All participants must wear a number bib at all times and a swim hat in the swim sections. These will be provided by AKA Mustard Events at registration.

All participants must carry a whistle to attract attention in an emergency.

All participants must wear trainers/running shoes throughout the event.

All participants must carry a soft/collapsible cup for use at water/aid stations. 

Wetsuits will be mandatory if water temperature is below 14 degrees.

All participants must carry a waterproof packaged pressure bandage/field dressing.

Participants may compete wearing a wetsuit, tri-suit or swimming gear and light weight T shirt subject to water temperature.      

There will be random kit checks at the race start, if you are not properly kitted you will not be permitted to race.

Optional equipment

You can use additional equipment to help in the swim such as paddles, buoyancy aids, etc. flotation devices MUST NOT be larger than 100cm x 60cm


Your time will be measured by electronic timing from the gun start until you cross the finish line.


We have a zero tolerance policy on litter. There will be lots of bins available for rubbish, if you are using gels as you are racing please pass your rubbish to the next marshal you see.  At the water station there will be bin bags available to put your rubbish in. If you are caught dropping litter you will be asked to leave the course and you will be disqualified.

Withdrawal from the race and retiring:

Marshals and race directors’ decisions are final. Abusive language and/or behaviour towards the marshals, organisers or directors will not be tolerated.

The marshals or race organisers can refuse to let a team or solo participant continue if they judge them to be too fatigued or in a physical/emotional condition that would endanger themselves or others. Please return to the race finish and hand in your number band.  

If you decide to retire/stop during the race please report to the nearest marshal. Do not leave the course without telling a marshal. You must then return to race finish to hand in your number band .  Failure to return your number band will result in a £10 charge.


A proportion of the run is off road and through some rough ground. Please be aware that there may be unexpected natural hazards i.e lumps, bumps, holes, mud. It is an adventure race so there may be hazards to climb over or navigate through.

Please only enter and exit the water where you are directed to do so. The swim entrances and exits have been chosen to limit ecological damage to the lakes and the river banks. They are also chosen to ensure whilst they are safe, they are also a challenge and add an element of adventure to the race. Marshals will be on hand to help you. Please note that you may feel disorientated as you stand up to exit the swims. Please take your time and listen to the marshal’s instructions.


If you feel you are struggling in the swim or need any assistance in the swim please roll over onto you back and put your arm in the air. This will attract attention and the safety team will attend to you.  With this in mind you are only permitted to swim on your front.

You may hold onto the front of any safety boat and when you are ready, continue with the swim as long as you make no forward progress whilst you are resting.

Unlike triathlon, you can help fellow competitors. We actively encourage you to help each other but you cannot have outside assistance.

The Event Course:

The courses will be clearly signed and swim entry and exit points are marshalled. Be observant and follow your colour arrows and tape

The final route maps will be available 4 weeks before the event in the Competitors Handbook. This will be available on the website, posted on social media and the link to it will be in your final email, which will be sent to, once entries have closed. Your final email is sent in bulk mail so it may end up in your Junk/spam folder.

The Race Director or Safety Officer reserves the right to change the race route at any point up to and including the day of the event.

Participants will be entering and exiting the bodies of water at various points, which will be marked and marshalled. Whilst every effort will be made to ensure participants safety you must be aware that being a natural environment there is every possibility of debris being present underfoot.
