Borneo Sea to Summit is a dramatic 120km ultramarathon which sees you traverse some of the most biodiverse rainforests in the world as you wind your way to Malaysia's highest mountain: Mount Kinabalu.
We will greet you in arrivals at Kota Kinabalu airport before transferring you to our comfortable hotel accommodation in the city centre. Once you've had a chance to rest and unpack we will meet on the waterfront for a sunset dinner as you get to know your fellow #ratracers!
The next day will give you the chance to start acclimatising to the heat and humidity. This is our registration day where we will give our full adventure briefing, answer any questions you might have and run through kit. We also have an optional excursion to Manuken Island for those who are itching to do a bit of exploring, this beautiful island is a great place to do a spot of snorkelling and to grab your first glimpses of the wildlife this area is famous for.
After a good night’s sleep our adventure begins! Over the next 4 days we will run/trek our way towards Mount Kinabalu, this magical journey will showcase the many beautiful rare species of flora and fauna that only exist in this rainforest. Keep your eyes peeled for orangutans and the native Thomas’Pygmy-squirrels and Black Shrews as we go from sea level to 4095m (with over 5800m elevation gained in total). After we’ve tapped the summit our descent includes a traverse of the world’s highest Via Ferrata which is an exhilarating way to wrap up our time on this stunning mountain before we continue the climb back down through the national park before jumping on our transfer to our beach resort hotel for our celebration meal and maybe a spot of karaoke!
DAY ONE: ARRIVE KOTA KINABALU AIRPORT (KKIA)
We will pick you up from the airport and transfer you to our accommodation before coming together for a sunset, waterfront dinner.
ACCOMMODATION: Twin Bedrooms,
DAY TWO: REGISTRATION, OPTIONAL ISLAND TOUR
After breakfast we'll go straight into our adventure briefing and Registration process, this day is a good chance to get used to the heat and humidity you'll be running or trekking in over the next 4 days. In the afternoon there's an opportunity to go to Manuken Island for spot of snorkelling and wildlife spotting for those who are up for a bit of exploring.
ACCOMMODATION: Twin Bedrooms,
MEALS: Breakfast, dinner
DAY THREE: THE ADVENTURE BEGINS (58KM)
Here we go! Our journey to Mount Kinabalu begins, to reach the National Park from sea level we have to hoover up 58km on road. With over 900m of elevation it's a bit of a beast as we march towards the jungle.
ACCOMMODATION: Twin Bedrooms,
MEALS: Breakfast, pit stop lunch, dinner
DAY FOUR: INTO THE JUNGLE (17KM)
If you know the jungle you know not to be fooled by the 'short' distance. Today is just 17km but the terrain is entirely off-road, tricky, technical and slippery underfoot. Today we'll rack up another 1200m of elevation and in the Test Pilot event this took our #ratracers nearly 7 hours to get through!
ACCOMMODATION: Twin Bedrooms,
MEALS: Breakfast, pit stop lunch, dinner
DAY FIVE: THE ASCENT CONTINUES (32KM)
An early start today (but not as early as tomorrow!) as we set off on our punchy 32km mountain trail route with a whopping 2800m as go from 1000m above sea level to over 3000m! The summit is now firmly in our sights and tomorrow we'll set off in the dark to reach the summit at sunrise.
ACCOMMODATION: Mountain hut (dorm style)
MEALS: Breakfast, pit stop lunch, dinner
DAY SIX: SUMMIT AT SUNRISE AND VIA FERRATA (14KM)
After a 2am wake up call and with our headtorches strapped on we will begin our final push to the summit just in time for sunrise. After the obligatory photos on the top of the highest mountain in Malaysia we will descend to the world's highest Via Ferrata for an adrenaline filled activity and a once in a lifetime opportunity to tick this off your list. All equipment is provided and with local guides on hand no previous experience of this is needed, just a keen sense of adventure! We will then continue our descent back to the edge of the park and our glorious finishline. After we've kicked off the celebrations here we'll jump aboard our transfer coaches to continue the party back at our beach resort hotel.
ACCOMMODATION: Twin bedrooms, beach resort
MEALS: Basic breakfast, pit stop lunch, celebration dinner
DAY SEVEN: HOME TIME
After a final breakfast together we will arrange early morning transfers to Kota Kinabalu airport for those who are heading home. If you are looking to relax and catch up on some sleep ahead of your journey home we would recommend booking another night at our resort to recharge those batteries after this epic adventure(extra nights can be booked by contacting us on firstname.lastname@example.org)
MEALS: Breakfast provided
All accommodation is always offered on a shared basis. If you are taking part on your own, you will be paired with another participant of the same sex in a twin room. If you have preferences for who you share with, you are able to specify that prior to departure. For mountain accommodation this is more dorm style.
Single supplements may be available subject to availability.
Breakfast at the accommodation is a fresh and varied local buffet. Breakfast on the mountain trails will be a more basic offering.
Each evening we will provide a meal which consists of good quality cooked, local food with dietary requirements catered for.
During the challenge you will have access to our Pit Stops.
Pit stops will typically have a minimum of the following available:
Water – Ensure you leave with water bottles and bladders filled so you have enough to get you to the next Pit Stop.
Salty snacks – such as crisps, dried fruit and peanuts, pretzels
Sweets – including local speciality sweet treats ,chocolate etc
Fruit - as you will see we will pass mango, coconut and pineapple farms on this route. We will be bringing as much fresh fruit as we can to you to keep you refreshed and energised.
Our Pit Stops are there to help supplement any personal sports nutrition plan you may have – if you use gels and other such products – you should plan to bring these with you. If you have any special dietary requirements, then please also plan for this and pack your kit accordingly. Rat Race aim to offer Pit Stop snacks that are tasty and functional, catering to as broad a mix of needs and diets as possible. We have options available that are suitable for vegetarian and vegan diets and availability of this will depend on demand. Rat Race cannot guarantee that the food does not contain contamination from allergens such as nuts or gluten in its preparation or serving.
Please make sure you sanitise your hands prior to eating any food. Please, please, please take care with your trash and help us in our aim of leaving these incredible islands tidier than we find them. This is even more critical in this environment, with any lost trash instantly becoming a choking hazard for the marine life we are here to admire.
The date-range is set and the routes are tried and tested. However, our challenges unfold in some of the most spectacular places on Earth. Sometimes we do have to change plans on account of weather, injury or other unforeseen factors. If we do have to do so, you will be informed and usually, these unforeseen changes simply add to the flavour of proceedings and provide for a good story to tell at day’s end! That having been said, our route is likely to remain largely intact, regardless of any on-the-ground changes.
Our pick-up location for this event is Kota Kinabalu International Airport. For anyone already here we can meet in town at the hotel, details will be provided closer to the event.
We have designed this challenge so that you may travel at your own pace. See below for our notes on route-finding and guidance. There will also be some cut-offs, but in the true Rat Race tradition these will be generous and we will always look to help you to achieve your goals in finishing this challenge, vs having to pull out. Of course, we will give you some early starts to allow the very best possible window for route completion. But, if you need us and if you need to abandon the route for whatever reason, we are there for you and can pick you up.
You will need to navigate on a GPX device, ideally a watch with a smartphone as a backup. We have devices available to rent if you need one. There are times in the jungle and on the mountain summit trails where you will be accompanied by Rat Race staff and local guides who will help navigate the route.
We will use a mixture of UK safety staff in cars, foot sweeps and local crew. You will be able to interact with medics and the Rat Race crew at Pit Stops..
RR has a lot of experience supporting people at altitude. Together with our medical provider, we will share information with you in advance about how you can prepare yourself for this ascent profile; and what you can expect when you are undertaking it. During our attempt, you will be under the supervision of our experienced trip leader, local guides and a professional medic. We will not take any chances at all with your safety and if anyone presents as unwell and altitude is suspected, we have a plan to get you down the mountain.
Whilst everyone is different physiologically when it comes to their disposition to altitude illness, it is worth noting that we have tested this route and this ascent profile. Of the test pilot group who took part in this trip in 2023, all individuals successfully summitted and no altitude illness presented.
We have built a format here that has a sensible and achievable altitude ascent profile and as stated above, we will take no chances ith anyone’s health and welfare when it comes to such an ascent
Click Buy Event Voucher Now and go through the sign up process, you’ll then be issued with an event voucher which will automatically reserve you a place in the event you have chosen.
Yes. You need a decent travel policy covering you for general travel and which covers participation in outdoor sports. You will also need what is called an Evacuation Insurance Policy, which is for if we need to send you back to the closest city for urgent medical attention via a helicopter or similar. We also recommend you have this in place as soon as you enter this event and that if you book flights, we highly recommend booking a flexible option for any last-minute changes you might need to make or to ensure you have maximum flexibility if you cannot attend for any reason.
Travel insurance is compulsory for our events, so please make sure your insurance policy covers the activities you will be participating in. There are a number of specialist providers available including Mann Broadbent.
No problem. Where we use hotels, rooms are offered on a twin / shared basis. If you wish to share with a fellow participant, you will be asked to add this information to your event participation form which we will issue you with approximately 3 months ahead of the event.
The short answer is no. The price for this event is for everything outlined on the website and it is very difficult for us to split this out. Our accommodation is based on group rates and is on a shared basis. All of our event logistics, support and organisation has been designed to have all the participants in the same locations to allow transfers, briefings etc to run smoothly and to let you bond with your fellow #ratracers!
Yes you can trek this, in the jungle and on the mountain trails everyone will end up trekking.
We take our medical care very seriously and we commence our commitment to you in this respect with a pre-depatture medical screening exercise, plus the dissemination of information on preparation and on the effects of altitude.
We will have a professional medic with us at all times, supporting you on every step of your journey including the mountain ascent phase. If you are feeling unwell, you can speak to our medic in confidence and we can decide the next appropriate steps. If altitude is suspected as a cause of your feeling unwell, the first port of call is usually to descend and such an eventuality is all planned for as part of our comprehensive Evacuation Planning activity. Rest assured, you are in the very good hands and there is a plan for your safety at every stage of the trip.
In typical Rat Race style we want to give you as long as possible to complete each day of this adventure. Our main cut off is sunset and we will support you as much as is practical to allow you to finish each day at your own speed.
We have firm emergency protocols and response systems in place whilst out on our adventures. Our main priority above all else is to keep you and our staff safe. Before we leave for each trip a comprehensive in-country risk and threat assessment has been conducted by the Head of Expeditions. All protocols are put in place relating to those assessments. We make sure that the staff involved have the highest level of first aid training; a higher level of medical cover is also put in place if needed; all instructors have qualifications and/ or competencies to match the adventure we will undertake. In the event of an emergency, Rat Race staff and appointed contractors have comprehensive knowledge of procedures which will rapidly be put in place. If needed, our staff will provide first aid and then further medical assistance and evacuation if needed in line with a published Medical Procedures Plan. We have medical back-up and Clinical Directorship provided by a specialist events medical company and we have further emergency response support services provided by competent contracted partner. All our cover is available 24/7 while operations are underway. We use our knowledge and emergency procedures to provide the best possible care in our often remote and austere environments. Before leaving on a trip, we will advise on the insurance cover you are required to have in place for the trip; we will ask for a copy of these insurance details before the departure date.
Once you’ve signed up, you will receive a confirmation email. After that, you will be kept in the loop closer to the event when we will send out our Essential Event Information approximately three months ahead of the event, detailing the full itinerary, what you need to bring and other important information relating to the specific event you have signed up for. We will also host webinars which you will be invited to (again, closer to the event), where you will have the opportunity to ask questions and go through your kit. There will be a final email one month ahead of the event, just to check you’ve completed all the important forms and are ready for the event ahead.
If you have chosen to pay in instalments, we will also contact you if any of your payments have been missed. Please ensure you regularly check your spam folders and have email@example.com and firstname.lastname@example.org added to your ‘approved / safe’ email senders.
Getting to the start line is important and we are there to help you as best we can. However, if you feel on reflection that it is just not your time yet, we do have a transfer system that you can use to transfer out, receive Rat Race credit and come back again next year or do something else. Credit is typically valid for 12 months and there is a fee to be paid for transferring out in this way. We want to be really clear that this option is there for you if you need it, but it does have a deadline. View our full terms and conditions here.
Race entry includes a brilliant finishers medal and bespoke event Rat Race tee. We will request your t-shirt size in the event details form 3 months ahead of the event and this will be the size you will be given at Registration.
See the 'Kit List' section. We provide all Via Ferrata equipment.
If you need to bail we will collect you via the Sweeper vehicles and move you forwards on the course (subject to medical advice if it is a medical issue that has forced you to pull out). If you need to pull out where we cannot access the route with vehicles as easily, in all cases we will ask you to move (or assist you to move) to a location where we can access by vehicle, or we will evacuate with medical and/ or safety personnel if required.
It is a mix of road and jungle/mountain trails.
