EVENT ETHOS: ‘RACING’ AND OUR FINISH TIMES SERVICE

Race’s ethos has always been about inspiring folk to undertake challenges in awesome outdoor locations. Santorini Circuit is just that, taken to an epic level. This is not a formal race environment and there are no winners and losers. We do not award prizes for the fastest folk. We will publish the times captured manually by our event crew for each day, in alphabetical order and for your information and comparison as we know everyone does their best and many want to see how their efforts compare to others. There will be no splits for Pit Stop to Pit Stop times. Rat Race totally appreciate the incredible commitment of those taking on the challenges we lay down and each participant is as important as the next regardless of how fast you can cover the distance on foot, bike or skate.

In delivering this unique challenge we prioritize factors such as safety, camaraderie and environmental concerns. Respecting the wishes of local stakeholders with our route management and litter policies is vital in being able to bring folk together for this unique experience. Safety above all else is paramount, as you will fully appreciate. To reasonably balance all these factors, we emphasize that the event is not a formal race environment, rather it is a challenge in the great outdoors where great folk come together with a common purpose.

TRANSFER DEADLINE

At the time of booking, on our website and within our introductory email on we made clear that your purchase is non-refundable. But up until 12 weeks prior to departure, you could use our transfer system if you wished to withdraw from the event. We respectfully remind all participants that unforeseen circumstances preventing attendance is what travel insurance is designed for and is the reason for this as a strong recommendation on such undertakings.

For the avoidance of doubt, the final day for transfers is Friday 10th July. We regret that we cannot provide any transfers once these deadline have passed. These are HARD deadlines as we go firm on all aspects of our planning after this stage. We cannot make any exceptions.

MANDATORY KIT 

Some of the kit listed is to help you have a safe experience and have the best chance of finishing. Some of this kit is to ensure that if you are unable to continue, and assistance is not immediately available, then we can be confident of you having the level of equipment required to keep you as comfortable as possible whilst you wait for that assistance. Some of it is simply to keep you from perishing. It is a serious list, and we know everyone knows this, but we ask that you please do work with us on this. Please do not skimp on kit.  

CLICK HERE TO DOWNLOAD MANDATORY KIT LIST

OIA KIT CHECK

In Santorini we will reserve the right to inspect some or all of your kit. This is an important part of our safety system and it is really important that you pack the right gear for this event. 

​As a minimum, at kit check will be checking the below.

  • Daypack or running vest for foot stages including water carrying capacity 
  • A first aid kit 
  • Suitable footwear for the foot stages and water stages
  • Salt tablets and dissolvable electrolytes for water
  • Navigation/GPS device
  • Collapsible cup
  • Smart Phone

There is no instant access to sports shops in Oia and the ability to ‘fill in any gaps’ is therefore heavily reduced.  

If in any doubt, please check well in advance on kit. We have devised the mandatory kit list for your protection and safety, and we will not be able to make any exceptions on required items. 

AVOIDING KIT CATASTROPHE IN TRANSIT

It is not impossible that your gear may not arrive with you into Santorini. In general, the longer you are in Santorini, the easier this is to solve. To avoid the chances of total catastrophe, we would recommend that you do travel with some event clothing in your hand luggage: A set of running kit and some trainers would be minimum recommended. Indeed, you can travel wearing this gear. 
 
Experience tells us that if you arrive wearing or physically carrying some of what you need, the likelihood of getting you on the start-line increases dramatically, vs those who entire event kit is in their hold baggage, making its way around a carousel in the wrong airport far, far away. 

BAGS & TRANSITIONS

Transitions

Saturday: you will take a ferry to Thirassia to complete your first run/hike stage. While there is no actual transition involved on this day, you may take a small bag with you on the ferry (in addition to the daypack/running vest that you will wear for the run/hike) which you may leave on the beach to be looked after by a member of our crew while you are running/hiking. For example, this bag could contain swimming gear, a towel, change of clothes etc.   

Sunday: there will be one main transition from kayak to run/hike. Your transition bag will be handed to a crew member on the morning and will be waiting for you at the end of the kayak stage. This bag contains anything you wish to access AFTER kayak and BEFORE the long run/hike stage – e.g. fresh running clothes, shoes and daypack/running vest. You may also leave items in this bag that you have used on the kayak and do not wish to carry with you on the run/hike. After you transition, this bag will be taken directly to the hotel – i.e. you will not see this bag again until after you’ve finished. 

Transition bags must be soft and not hard suitcase-style cases, ideally dry bags so protected from any weather and no more than 30l each in size. Small holdalls, duffels or rucksacks are fine

Bags

There are multiple bags to be considered for this journey: 

  1. General ‘overnight’ bag: (recommended: Holdall or duffel) for spare and general kit.
  2. Daypack or running vest: This is the bag you will carry with you for the two run/hikes. This should be big enough to carry all the mandatory kit, with 2 litres of water.
  3. Transition bag: to be used on Saturday and Sunday as specified in the transitions section

DAY TO DAY

ACCOMMODATION

Agnadi View Villa 

Accommodation will be provided across a mix of 2/3/4-bed studios and apartments. 

If you wish to share a room with a fellow participant, you will have the opportunity to request this on your Event Participation Form. If you are taking part on your own, you will be paired with another participant/s of the same sex. 

FOOD AND BEVERAGE

The itinerary is on a Bed & Breakfast basis. 

On event days you will be supported by Rat Race Pit Stops: 1 on Thirassia (Saturday) and 5 on Thira (Sunday). Pit Stops will be spaced out as evenly as possible and feature water, small grab-and-go snacks and other treats. At Pit Stop 2 on Thira there will typically be some more substantial savoury ‘lunch’ items such as wraps and bread. 

You should look to augment these Pit Stops with your own snacks and you should very definitely provide your own hydration, electrolyte and sports nutrition supplies. This will be important throughout your adventure. You will pass some tavernas and shops along the middle section of the route, you are more than welcome to pop in and get yourself a cold drink or a well-deserved ice cream. 

On the Sunday night in Oia we will provide a celebration dinner at a great local restaurant. 

ALCOHOLIC DRINKS AND EXTRAS

Where we provide meals as part of the general event service, we will not include alcoholic or soft drinks as standard and these must be provided by yourselves. 

Please ensure that you settle any personal bar tabs at the hotel before you leave.  

ABLUTIONS AND HYGIENE

Toilets will not be available at pit stops. We recommend that you take advantage of the facilities available in cafes that you pass along the route. However, you will inevitably find yourself needing to go to the toilet in the wild at some point along the course.  

The firm advice is always to ensure you are ‘self-contained’ with toilet roll and anti-bacterial hand gel for the trail. Do NOT leave toilet paper or human waste out on the route, please bring nappy bags to contain this waste and dispose of in the nearest bin or at the next pit stop.  

You should keep to a high level of personal hygiene and keep your hands clean by using wet wipes and antibacterial gel where soap and water is not available.

STYLE OF TRAVEL

There will be 20-40 participants taking part in the event, depending on the weekend.   

You will kayak in pods. Each pod will be a group of approximately 10 people. The kayaks are double sea kayaks. You can go with a friend, or you may be paired up with another participant. Each pod will have a qualified sea kayak instructor. The pods will stay together throughout the kayak stage. This is for the safety and management of the full team. A safety boat will be present throughout the kayaking stage to support the event.   

For the run/hike stages, you can go at your own pace. Run or hike with others, run or hike on your own, whatever you fancy. We will not stop you trekking unless you look unlikely to finish in daylight. As such, there are no formal cut-off times at the pit stops – it is very much down to the judgement of the event team. We can help and assist every step of the way. We are there to support you and if this means boosting you forward by vehicle, we will do so to enable you to finish on a high. Unless we think you’re going to run out of daylight, we will not cut you off. That is our pledge to you. For your part, just keep moving forward.

ROUTE

OVERVIEW

Santorini comprises two main islands: Thira (the larger island – we will be staying in Oia, in the north of the island) and Thirassia (the smaller of the two islands). Your adventure takes place on both islands on two consecutive days: 

SATURDAY: You will take the ferry from Amoudi Bay across to the island of Thirassia. Exiting the boat at Riva Beach, you will set off on a 13km run/hike which will take you via roads and tracks to the southern tip of the island before returning to Riva Beach. You’ll pass many a beautiful chapel and ruin before reaching the Monastery of Kera at Cape Trypiti. From here you can see the Akrotiri Lighthouse marking the southern tip of Thira. 

SUNDAY: The day begins with an 6km paddle around the southwest tip of Thira from Paralia Vlichada to Mesa Pigadia. It's here that you will start the final stage – a 36km run/hike to the northern tip of the island via the summit of Mount Profitis Ilias. At 567m, this is the highest point on Santorini and you will be met with stunning views of the whole island, the volcano and the deep blue sea. From here you’ll also be able to spot your final destination in the distance – the beautiful town of Oia. As you descend the mountain, you will re-join the coastal path, high up on the cliffs overlooking the caldera, as you pass through the stunning whitewashed village of Fira. The final 10km is a highlight of the entire route and is a trail runner’s dream. We will be waiting for you in the centre of Oia to welcome you in and celebrate your achievement! 

ROUTE FINDING & GPS

We will NOT waymark the route EXCEPT for small sections where we think it might be absolutely necessary. 

In general, this event is operated with GPS as the main method of route guidance. YOU need to bring a GPS watch and a navigation device or application on your phone. It is imperative that you are well versed in the usage of your own device and that you are confident in their battery life and reliability. 

We will provide you with GPX files for you to upload onto your own devices. These files will be provided much closer to the event once we are satisfied that we have the final version to share. Experience has shown that we will never share the file until it is the final, final, final version. Or else we end up with version control issues that are hard to resolve. 

If you wish to rent a GPS watch from us, you can do so via your RR account. This will have the GPS already uploaded and you will get tuition on how to use the watch on registration day. 

PIT STOPS

Each pit stop will feature a vehicle, staff, first aid support, comms and of course, some food and drink. Expect the odd cameo local snack appearance, some baked goods from time to time, plenty of sweets and salty snacks and loads of fresh fruit.   

General note on food – trail snacks  
Please pack your own hearty supply of snacks and electrolytes that you enjoy on the trail. 

TRAINING AND PREPARATION

The Santorini Circuit is a substantial undertaking. Even with a reduced kayak leg and splitting the on-foot distance over two days, the main event day on Sunday will be a very long, hot day for most. Santorini is a beautiful island, but it will pack a punch. The foot sections can be run or hiked, aim for a minimum pace of 3mph/5kph and you will have plenty of time to finish. Training should now be focusing on long days on foot – up to 6-8hrs, if hiking. 

Do not avoid hills, hill strength will be the key to success: Santorini is not flat. If you don’t have access to multiple hills, do some hills repeats to strengthen the legs. We understand it is by no means easy for everyone to fit in the training – everyone is different, everyone has different day-to-day pressures and commitments, life throws many curve balls – but being physically fit for this challenge will make it more enjoyable.  

Train with the kit you are planning to wear. You will then be able to check if it is comfortable and fits correctly. Chuck on the bag that you are going to be running or hiking with, fill it with some tasty snacks and water, this will help your body to get used to the extra weight on your back. The fitter and more prepared you are for a challenge like this, the more you can enjoy every moment of it.

MEDICAL & SAFETY

INSURANCE

We have asked that you have in place Travel Insurance cover and specified Evacuation cover to last for a minimum period of the event duration for the days you are with us on the published itinerary. Evacuation and medical expenses cover should total no less than $500 000. A copy of this cover/covers (if separate policies) is required to be received by us by 8th August 2025. The details for submission can be seen at the bottom of this EEI in the ‘checklist’ section.  

We recommend that participants have insurance to cover damage, loss, theft, injury and non-attendance. Rat Race cannot accept any responsibility for the loss of, theft, or damage to any Participant property or the circumstances of Participant non-attendance. Within the 12-week departure window, we cannot provide any transfers and, in all cases, we cannot entertain requests for refunds. We respectfully remind all participants that unforeseen circumstances preventing attendance is what travel insurance is designed for and is the reason for this as a strong recommendation on such undertakings.  

You can submit copies of your insurance via the online form here. Alongside this, we ask that medical screening is completed, plus an online waiver. Please see the actions list at the bottom of this document for details. 

Some suggested providers are as follows:  
 
For UK and Channel Island residents Rat Race’s own insurer brokers have a brand-new product: https://www.mannbroadbent.co.uk/sports-travel-insurance/


Note: This is Rat Race’s UK-based insurance broker, specialising in the leisure insurance market. This is a specialist sports travel cover product; however, Rat Race is neither an insurance broker or underwriter. We can recommend Mann Broadbent wholeheartedly as good people to deal with, but please remember that this is not a ‘Rat Race product’ and we have no say whatsoever on claims decisions made by the insurers, in the event that you raise such a claim via one of these policies.  
 

Other providers: 

Note: We have no relationship with any of these providers, but previous customers have found them reasonable to deal with regarding some of our similar Bucket List challenges.  
 
Note: For all insurance, please remember that cover is offered based on several factors, (the nature of the event disciplines being one of them), but your own insurance profile, age, health and other details form a big part of this. As such, we are always happy to provide details to insurers in support of cover requests from customers, but we cannot influence their decisions as to whether to offer cover to individuals.  

COURSE CUT OFFS & WITHDRAWALS

This event is not about cut-offs. But, having a ‘cut-off’ and a ‘sweeping’ structure is an important part of our Event Management Plan and Risk Assessment processes. Cut off times are independent of any other factors that occur earlier in the course such as start time, injury, going the wrong way, time taken at Pit Stops, head winds; and whether it is your fault or not. We understand that missing cut offs can be tough to take but please remember this is not the crew member’s fault that breaks the news to you, should it happen to you. Please also remember that if this does happen to you, the Event team’s decision is final.  ​

There are a number of reasons why you may be cut-off or withdrawn from the event. These could be medical, pace, kit, personal or other factors.  

As far as the time available goes to avoid a cut-off, there is no ‘set’ cut off time . (ie. time limit or published time). Instead, we require all participants to be at the finish location before nightfall. If this is looking unlikely you will be ‘swept’ or 'boosted' forward. That is the cut-off.  

Above all else, please remember, this event is not about cut-offs. It is about getting the most out of this magical environment. We will not cut you off and sweep you forward unless we really must. And if we do, it is for your own safety.

GPS TRACKING SYSTEM

Rat Race utilises top-tier satellite tracking units attached directly to your running pack. There are two main purposes for this.  

The primary function is safety and Race Management. It allows our event team to ensure everyone is following the correct event route, and will aid us in advising you if you have wandered off course. Further, in the instance that you or someone near you comes into difficulty, it helps us to find you and get help to you more quickly.  

The secondary function is spectator tracking. There will be a public tracking map link generated for family and friends to view your progress from home. 

Crucial Note for Friends & Family: Satellite tracking technology is not entirely infallible. Signal drops can occur in deep valleys, or units can temporarily freeze if blocked by heavy gear inside a pack. Please explicitly warn your friends and family not to panic or contact local emergency services if your tracker stops moving on the map. Our dedicated event safety team monitors the tracking matrix constantly. If an anomaly occurs, we have internal protocols to verify your safety. Third-party interference can severely disrupt active event management and waste emergency services’ time. 

MEDICAL FORM

We will have a medic with us for the duration of the trip and they are available for you to interact with in confidence if you experience any medical issues. Whilst the medics are there for ‘what ifs,’ they are also a great source of preventative advice; so please do use them to ask questions and check best practice, particularly in suspected foot injury or issues such as blisters. 

Medical Form

At this stage we are inviting you to have a medical screening process, which can be completed via the link below. Please complete this as soon as possible – and certainly please, no later than 2nd August. You can do so HERE. If you do have any condition that you feel we should know about, however small you feel it may be, please do share this with our Medics. Experience has shown that early pre-screening can assist both us and you greatly in enabling the care you need pre and during the trip. If you do not share information on conditions which are likely to affect your participation or decide to share them very late in the process, we are all under pressure and we will always reserve the right to cancel your participation if we feel there is a medical issue that may affect yours, or others’ safety. So please, do share anything and everything you feel our team should know about, at the earliest opportunity. Please view our latest Health Information HERE.

IMPORTANT NOTE ON SUBMISSION OF DOCUMENTS AND MEDICAL INFORMATION:

We are very fortunate to have an excellent Medical Director providing oversight, planning and screening on all of our international trips, who in turn engages seriously professional and qualified staff to join you on the trip. Rat Race also conforms and has been audited to the rigorous BS8848 standard of expedition management. This means our approach to all things safety and medical is extremely thorough and it is designed throughout with your best interest at heart.

Your medical screening details will be sent direct to our medical team and under medical confidentiality rules, this will only be shared with our medics and no-one else. If they decide this is info that is in the best interests of everyone for us as organisers to be privy to, they will seek and gain your consent before doing so. It is therefore important you complete the link to the medical survey only which can be found HERE. Do not send Rat Race medical information direct. If you have any queries at all on the medical side of things in relation to this event, you can email our Medical Director, Dr Patrick Musto confidentially on office@trailmed.com and he and his team will assist.

POOR WEATHER AND CONTINGENCIES

Santorini’s popularity with tourists coupled with high temperatures in the summer months makes October the preferred month for this event as it is both quieter and cooler. However, falling later in the season does mean that the weather can be more temperamental. If wind conditions are too high and sea states too rough, the kayak route may have to change. 

It will be rare that the kayak will be completely cancelled. However, it is not impossible.  

If we deem the sea state to be too large for any kayaking to be done safely, we will complete the run/hike section only on Sunday. However, the route will be extended slightly to start from Akrotiri lighthouse. 

EMERGENCY PROTOCOL

In the event of a true emergency or serious incident you will be notified of protocols at the orientation in Oia. If you are with an injured party whilst on the route, stay with the casualty and await assistance. In the event of a non-emergency incident but for which action is requested from the organisers, then you should place a call (we will give you numbers) or if no phone reception, you should send a message forward to the next Pit Stop with another participant if possible and/or await an event crew member approaching via vehicle/or on foot from behind. This might be medical, logistical or kit/ equipment breakdown as examples. We politely ask that you stop and help someone that is in difficulty – you will be the first person to find them – remember to take note of time, place (number of km, or minutes/ hours from last Pit Stop) and participant number/ name at the incident site. Remember we are all in it together and we are in effect one big team.

TRAVEL MEDICINE ADVICE

As well as being a practising NHS Emergency Care Doctor and Expedition Medicine Specialist, Dr Musto is also a qualified travel medicine practitioner.  Please view the Travel Medicine Advice PDF HERE

SUN & HEAT

Please carefully review our Sun & Heat safety guidance issued by our medical partner Trail Med.

SAFETY AROUND VEHICLES

This event takes place on the trail and open roads. There are vehicles, this is not a closed road event. Vigilance must be always taken.  

MUSIC PLAYERS

While these are allowed, please control their volume according to your environment. Always use your judgment when listening to music or audiobooks. Please also be aware that if you cannot hear general voice levels you might miss instructions or warnings from crew, other participants or approaching vehicles.
