200,000Kcal in 10 days… Extreme Expedition Nutrition

200,000Kcal in 10 days…

…Extreme Expedition Nutrition

Most people have heard the story of Captain Scott, the famous Antarctic Explorer whose ill-fated Terra Nova Expedition cost the lives of him and his men through starvation and the extreme cold. If you haven’t, it’s worth a read… 

Expeditions are known for their adventure, exploration, excitement, and discovery, but also for their danger. Anyone that has a love of the outdoors has been regaled with the stories of famous explorers such as Scott, Shackleton, Hillary, Tenzing, and Sir Ranulf Fiennes. Their adventures are talked about with awe and wanderlust, to such a level that people still try and recreate them even today.

But expeditions are not just confined to the most epic of proportions such as the ones undertaken by the explorers mentioned above, they come in all forms and occur all over the globe. From solo to group, jungle to mountain, desert to arctic, an expedition is what you decide it to be. Each expedition will require a different set of skills, different equipment, different route plans, and just as importantly as everything else, a different nutritional plan. Keeping the body fuelled to the right level requires detailed planning, taking in to account all the factors that will affect energy expenditure. Getting this wrong can result in fatigue, weight loss, and in extreme cases, death, such as Captain Scott and his team.

The inherent dangers that come with expeditions can be offset by detailed planning of every aspect of each trip, and emergency plans should things go awry. This includes Nutrition. Working out ‘Energy in Vs Energy out’ might seem simple enough, but most serious expeditions will come with the problem of ‘you can only take what you can carry’. Indeed they often require a heavy physical burden, carrying all your own food and equipment, regularly over long distances through difficult terrain, and often in harsh weather systems. So while 600miles may not seem too bad for an un-laden, well fed person in reasonable fitness; add a 20kg pack, a few mountains, and freezing weather to the occasion and your energy expenditure will increase dramatically.

We have come a long way since the days of Captain Scott’s wholesome diet of pemmican and water (a mixture of fat and dried beef), pony meat, and biscuits. It has been estimated that the Terra Nova expedition rations were 2000-3000 calories short of what was needed each day to meet the physical demands of the trip. Today there are many different companies that sell pre-packaged dry or wet rations, energy bars, and drinks powders, full of all the nutrients you need to sustain you body and suit your expedition needs. But that doesn’t remove the need for careful planning. 


Rations for one man for one day while man hauling during Captain Scott’s Expedition, we now know this is insufficient food for the conditions and work rate.

Energy output needs to be estimated per day, and rations need to contain enough Calories (Kcal), with the right amount of macronutrients, which are Protein, Carbohydrate, and Fat, to ensure your body can continue working to its full capacity.

Carbohydrates are the body’s main source of energy production. The body’s tissues require a constant supply of glucose, which is used as a fuel. The main source of glucose is dietary carbohydrate but it can also be synthesised from protein. If the diet is low in carbohydrate, a greater percentage of dietary protein is used to provide glucose, which means less is available for the growth and repair of body tissues. Thus, adequate carbohydrate in the diet has a protein-sparing effect. 1g of Carbohydrate equates to just under than 4 Kcals.

Similarly, 1g of Protein equates to exactly 4Kcals. All cells and tissues contain protein, therefore protein is essential for growth and repair, which is especially important during the heavy physical exertion undertaken during expeditions. The Reference Nutrient Intake (RNI) is set at 0.75g of protein per kilogram bodyweight per day, but studies suggest that endurance athletes require a higher intake.

Protein provides the body with approximately 10 to 15% of its dietary energy and it is the second most abundant compound in the body, following water. A large proportion of this will be muscle (43% on average) with significant proportions being present in skin (15%) and blood (16%).  However, if carbohydrate stores are low, Protein is used as an anaerobic fuel, making it less available to repair tissue. Therefore, on an expedition it is advised that people consume a higher intake of protein.

Fat is the richest and most concentrated source of dietary energy available in the diet, with 1g of fat equating to 9Kcals. It is also the carrier for fat-soluble vitamins A, D, E and K. The Department of Health recommend that the average diet should have a fat intake of 35% of food energy.

Once you have ensured that your expedition diet contains the right macronutrients, you need to work out how much you need individually for your expedition.

Factors that may affect your energy needs include

  • Distance
  • Speed at which you are travelling
  • Terrain and incline of route
  • Weight carried
  • Temperature of environment
  • Basal metabolic Rate


We have been working very closely with our nutrition sponsors High5 Sports Nutrition, and TentMeals, to work out a detailed nutrition plan for the Patagonian Expedition Race. We have also sought the advice of a qualified Dietitian who has reviewed and approved our plan.

Working to ensure a constant fuel supply and reduce energy dips and fatigue, the team will consume food every 30-40 minutes on the go, using a mix of energy bars, trail mix, and ‘main meals’, which will be broken down into 4 smaller meals to improve movement and timing.

The High5 Energy Bars are a healthy low GI snack with a balance of simple and complex carbohydrate from fruit and grains. Each bar provides one of our 5-a-day fruit / veg portions, and It’s moist, easy to chew, and will not melt in the heat or become hard in the cold. Each bar will provide us with 195Kcals, with 40g of carbs, 2.4g of protein, and 2.6g of Fat.

These will be mixed with the 4:1 Bars, which are similar but provide a larger intake of protein to aid muscle recovery and repair, at 7g per bar!

This will be along side the use of electrolyte and fuel based sports drinks, which will help to prevent muscle cramping and add an extra energy source. 


High5’s 2:1 fructose ‘Energy Source’ drink is known as an advanced sports drink due to its capability to allow the body to absorb higher amounts of carbohydrate per hour from traditional sports drinks, from 60g per hour to 90g per hour! This gives a significant advantage to keeping the body fuelled. 

Again, this will be used in turn with the 4:1 Sports drink which is similar to the EnergySource but contains 9g of Protein per sachet. 

Towards the end of each day (if there is an end to the day!) the Team will consume a protein based muscle recovery drink, followed by their final ‘main meal’ an hour or two later.

High5’s Protein Recovery drink provides 18g of protein per sachet, and has the benefit of being able to be mixed with water rather than milk, meaning we can use it on the go with Patagonia’s plentiful supply of natural water (purified!).

Our ‘main meals’ are being provided by TentMeals, a company founded in 2015 with the aim of making lightweight, high density, camping and expedition food, that (wait for it)… Tastes good!!! Each Tent Meal provides 800-900 Kcal and weighs only 200grams! This combination means they are easy to carry on longer expeditions, and will provide enough Kcal to keep us going, while providing nutrition and a good hearty meal to keep morale up on the long cold days in Patagonia.


In hot water (we have JetBoils!) TentMeals take only 7 minutes to hydrate, and in cold water up to 30 minutes. This means we can have a hot breakfast, and stick a TentMeal in Tupperware in our pack at the same time to hydrate on the go. Simple, effective, tasty.

Below is the rough plan, that will obviously be largely flexible around our days activities. As you can see we are looking at individually consuming around 5000Kcal per day, and over 100g of Protein…. That is a lot of food!

Nutrition Plan

Added up for the whole Team, that works out at 200,000Kcal for the race, what an average person would take nearly 3 months to consume.

So there we have it, Expedition Nutrition in a nutshell!



TopTips from World Champion Adventure Racer

7 Top Tips from the World Champion Adventure Racer Nick Gracie

When Natalie and I agreed to enter the 2016 Patagonian Expedition Race we thought it prudent to do some research. After scanning the internet and pouring over social media we decided to learn the truth behind the ‘Last Wild Race’ from the person who really knows. Adventure Racing World Champion Nick Gracie, who has won the race three times with his UK Team GodZone (formerly Team Addidas Terrex), and who have collectively won it an incredible four times! We caught up with Nick in his Bristol home where he divulged his top Adventure Racing tips.

Learn the secrets of winning an Expedition Race…

We originally signed up to join the Patagonian Expedition Race (PER) team to help out our friend Steven, who wanted to establish a charity that supported veteran’s suffering from Post Traumatic Stress Disorder (PTSD). The Green Sentinels Adventure Team was intended to showcase the fledgling organisation’s work. As time progressed, and things within the Team changed, Natalie and I felt it was also a great opportunity to raise money for three other very worthy charities: Help for Heroes, ShelterBox and The Royal Marsden Cancer Charity.

We are raising money for three amazing charities, all whom have a personal connection with team members: Help for Heroes, The Royal Marsden Cancer Charity and ShelterBox


Much is made of sports sponsorship deal, that’s the point! This is a massive topic, with loads of great advice available online. We’ll be sharing our experiences in a future post. But the general idea is that you, and a business with something to promote, enter into a ‘special relationship’ in order to satisfy both parties. Sounds easy, right?

  • Up&Go Campervan
  • Tent Meals logo
  • FullSizeRender

When considering your event, as we found, you are not alone. In fact you are in competition with many other similar worthy individuals/teams/events looking for support. Companies can be very particular about who they support. So you have to understand their demographic, and if possible stand out by offering them something unique. Nick’s advice was that most of his sponsorship comes from personal relationships “through people the team know within organisations; they are key as they’re the ones who can get you in front of the right decision maker.” It’s not easy and as Nick pointed out “you’re almost better off working and buying the equipment yourself”. The key here is to do your research, ask everyone and follow things through.

Again each team is different but so far we have found that through hard work, good research, and sticking to our values, we came up trumps. We’ve built some excellent sponsorship relationships for our race, and for future Adventures.


Whilst it’s easy to think about the kit you need, how fit you need to be, what you’ll eat, “just getting to the start line is an adventure in itself” Nick told us. It takes detailed planning to bring together all the items of equipment and the team to one of the most remote parts of the world. For the Green Sentinels this is still work in progress, as we’re still planning for the race itself. We are working on reporting back after the event to let you know how we got on!

Team Dynamics

Getting the right people is critical. Luckily I have some experience of this. At the time of writing we have just confirmed our fourth team member, Ben Hill, having unfortunately lost several people along the way, due to work commitments or health issues. Getting the balance of skills, attitude, and fitness is difficult, yet crucial in a race like the PER. Look out for my future post on the 4-7-1 model developed by National Outdoor Leadership School (NOLS) which I have adapted and applied to ShelterBox Response Team Training and my own consultancy work.  


When we met with Nick we had just hit the two months to go mark. “At this stage you are not going to get significantly fitter” he told us. “But you can get out together, which will help enormously” he added. Over the last 18 months, the team have all been maintaining their personal fitness, under the watchful eye of team member and NHS physiotherapist Natalie, whilst undertaken varying team endurance events, led by myself. These events have typically focused on endurance, and more specific skills the team need, such as mountain biking, sea kayaking, long distance walking, and rope skills. Check out our training video below…

Natalie has kindly put together a personal fitness programme which we are happy to forward to you if interested…

Race Tactics

Nick’s advice was succinct from the outset “Have a clear objective that all the team buy into”. Whilst discussing tactics with Nick we explained that from our early stages of planning we had decided that as a novice team, going into a race of this nature with the intention to win, was not realistic and potentially dangerous. Experienced teams like Team GodZone aim to complete the race in 5- 6 of the allotted 10 days and plan accordingly. Team members are chosen to fulfil that aim, and expect to win! As this is our first race, and we don’t have the financial backing of the bigger teams, we are planning to complete each stage within the allotted time.

Whilst this may seem uncompetitive, or not aggressive enough, it’s a considered tactical decision, and one that Nick totally agreed with. “Aiming for that top spot, as a novice team, would cause you too many problems, let alone putting some of the team at risk” he explained. We discussed at length the typical terrain, steep heavily foliated scrub/forest and wet bog, which can make progress painfully slow. Nick pointed out that our background in outdoor pursuits, expeditions, and military, will provide a great basis for what is to come. “You’ll have the right skill set, and a good chance of completing it…” Nick joked “…and remember, in 2014 only 3 teams completed the race out of 16. By completing it, teams got placed!”

Food for thought…! 


Good nutrition is obviously critical to the success of any adventure, especially an autonomous, unsupported one, like the Patagonian Expedition Race. Carrying sufficient food will contribute considerable weight and bulk to our packs. In addition, having spent plenty of time living on expedition food and Army Ration packs, they are not always the tastiest, especially given Natalie and I are vegetarians!


So to find a healthy, nutritional, and practicable solution Natalie has been developing an innovative race menu for the team. On Nick’s advice we’ll be pre-preparing 24 hour food bags in large zip lock bags, which can be distributed amongst the transition kit. Each bag will contain enough food & snacks for us on the move. Natalie has been working with our partners TentMeals, Up&Go and High5 Nutrition to develop a detailed and well balanced nutritional menu. Specific details of our plan, and the products we will be using during the race, will be contained within a future post.


Having the ‘right’ equipment for your chosen activity is a significant part of planning for any adventure. Whilst being wet, cold, and hungry is often an inevitable part of any trip, having the appropriate equipment to deal with situations as they arise, can make the difference between ‘dealing with things comfortably’ and ‘life and death’. Such an obviously integral part of any adventure warrants the plethora of information and advice available, from product manufacturers, outdoor retailers, brand marketers, online forums and chat rooms, and even enthusiastic adventurers like ourselves. Consequently, making informed decisions regarding the right equipment can become an over whelming factor when planning any adventure. Getting the right balance of factors like cost, quality, weight, and durability can often become an insurmountable barrier to even starting. 


Planning what to take on your trip takes a mix of experience, technical know-how, effective research, and a spot of good fortune to prepare successfully for any trip, and the PER is no exception. However on all the trips, including international expeditions I’ve been on, there’s never a perfect solution. Many of the decisions you make as to what to take with you is based upon making well informed compromises. And therefore requires an element of risk.

As with most planned trips the PER Race Organisers have stipulated a mandatory kit list for all teams. The remote wilderness environment of southern Chilean Patagonia is famously unforgiving and so their experience of what is required in that environment has obviously acted as our starting point for equipment selection. However it isn’t comprehensive as it doesn’t include everything we require for an expedition of this nature. So we’ve sought information from friends with experience in the environment including Nick and, Patagonian Kayaking Guide and Scotland’s Young Adventurer of the Year, Will Copestake. We contacted numerous manufacturers directly, as well as various retailers, including Cotswold Outdoor, Sea Kayaking Cornwall and Comrie Croft Bikes

Our resulting kit list is an interpretation of all that advice and has been influenced by what is available to us through generous donations, borrowing, product sponsorship, but mainly through personal financing. If you would like to assist us then please sponsor the Team below.

Corporate Sponsorship

Have your business displayed in the international media

We are funding the majority of this expedition ourselves. By sponsoring us you will enable us to raise more money for our chosen charities.

Nick will be sharing his rich racing experience on 7th of January, 2016 in Bristol and will be on hand to provide tips on how to prepare for a race in one of the wildest landscapes on earth. Admission is FREE, but places are limited.

8 Weeks to go!

With only 8 weeks to go the Green Sentinels Adventure Team are busy making final preparations prior to undertaking the coveted Patagonian Expedition Race 13th – 26th February 2016. The team of four will be representing the UK in one of the most challenging internationally televised adventure races across 500 miles of Chilean wilderness, whilst raising money for three very worthwhile charities – ShelterBox, Help for Heros and the Royal Marsden Cancer Charity.

Selected to represent the UK ‘The Green Sentinels’ – a team consisting of Ben Spurway (43), Natalie Gardner (29), Ben Hill (25) and James Gardner (21) – will be pitted up against 20 other teams from across the world.

Billed as the ‘laPER 2013st wild race’ and seen by the International Adventure Racing community as the ‘jewel in the crown’ in
the series of multi-sport events. The team will trek, mountain bike and sea kayak through the wild and untouched Patagonian Region of Chile’s Extreme South for ten-days in February 2016, with the route only being presented to the team 24 hours before they start. See the video here

The Green Sentinels consist of former or serving Regular Army and Army Reserve personnel and were founded with the aim of highlighting the plight of injured service personnel. Green SentinelsAcknowledged by renowned explorer Sir Ranulph Fiennes who said “The Green Sentinels is a brave and courageous cause that will positively change the lives of suffering ex-servicemen and their loved ones in a truly inspiring way”.  The team who all have extensive outdoor and military experience comprises of an Adventure Training Instructor and international Expedition Leader, a Physiotherapist, a Physical Training Instructor and an Engineering Student.

The Green Sentinels will delve deep into the uncharted region facing snow capped mount
ains, indigenous forest, impenetrable scrub, raging rivers, expansive fjords, and spectacular glaciers, on their ten day endeavor.
As they will be travelling autonomously between stages they have been taking their training very seriously. Race strategy and teamwork are acknowledged aNav Ex 1s key factors in the Patagonian Expedition Race by three times winner Nick Gracie, of Team GodZone, who has been mentoring the team. With this in mind the Green Sentinels have worked with the Team GB kayak coach on their Sea Kayaking skills during an expedition in the Scottish highlands, underwent mountain bike training in North Wales and have undertaken a three-day 100 miles endurance navigation exercise in the Lake District. Watch their training video here. The group has also been utilising their military training, completing assault courses, competitions, mountain training, weighted marches, and regular fitness sessions.

The Green Sentinels are fundraising for the Royal Marsden Cancer Charity, Help for Heros and ShelterBox. They have a wide range of corporate sponsors and support from Up&Go, High5 Sports Nutrition, World Challenge Expeditions, VictorinoxMereo Performance Wear, Gorilla Gear Tech, Sea Kayaking Cornwall, Army Reserve and Comrie Croft Bikes  but are still looking for further support.

You can find out more about the Green Sentinels here and donate to their charities here  or contact Ben Spurway, the Team Lead via, hello@greensentinels.uk

Taking ownership of the new van. #VanLife

After much deliberation and internet research we have finally done it! We’ve brought a van. A lovely second-hand 2007 Renault Trafic high top. Work will commence immediately on making it a comfortable and practical vehicle from which to launch our adventures.

Over the coming months we will be working to improve its functionality, and slowing turning it into a comfortable campervan for two and a dog. As we go we hope to test out the vehicles suitability for longer trips but initially our plan will include:

1. Deep clean

The van has been used as Trade vehicle and is subsequently pretty dirty inside. Today we’ll begin work to strip out and replace the paneling in the back. It’ll need power washing tor move some of the dirt. We can then have the cab valeted.

2. First stage modifications

To turn it from a panel van into an AdventureLife24 vehicle we need to make some simple modifications. We need to

  • remove the bulkhead (which we can hopefully sell on eBay)
  • insulate the floor
  • fit seats (we purchased two mini-bus seats from the garage)
  • put windows in the doors (still to be sourced)
  • remove and repaint the heavy duty roofrack and ladder

3. Electrics

Before putting all the paneling back in the van we need to add a 240v electrical system to power life’s little essentials. This will include:

  • a leisure battery
  • fuse board
  • electrical hook up
  • 240v sockets
  • lights

4. Second stage modifications: Camper conversion

It is hoped to eventually use the van as a camper for longer, more comfortable journeys. This will require fitting all the fixtures and firings associated with a campervan. It’ll also mean we can change the v5 and claim cheaper insurance and ferry tickets. We plan to fit:

  • rock n roll bed
  • cabinets
  • cooker
  • sink with running water
  • toilet
  • revolving captain’s seat
  • windows in the rear doors
  • sky light
  • carpet

We will update this site, and improve the quality of our blog posts, along the way.

Why we started Adventure Life 24…

So we decided to start a blog. I know, as if you don’t see enough of us already!

Having had some pretty awesome trips recently, as well as having some pretty exciting things coming up in the next 12 months, including the Patagonian Expedition Race with the Green Sentinels, learning to Paraglide with the RAF, a trip to the Alps, an expedition to the Atlas Mountains in Morocco, and a trek to Everest Base Camp, Nepal, it seems appropriate to capture it!

The idea coincided with an opportunity to write for World Challenge, who Ben has led expeditions for, as part of their expedition leader blog as well as being asked to review various items of equipment for Suunto, Gorilla Gear Tech and Columbia Sportswear.

So Adventure Life 24 is the result…

..we hope you enjoy it!

Welcome to our Adventure…
