In 2017, two close friends named Max Thorpe and Chris Williams participated in the gruelling Talisker Whisky Atlantic Challenge, a 3,000-mile row from the Canary Islands to Antigua and Barbuda. Things were looking up as the pair started the race at record pace.  

But then their world was turned upside down. Literally. Amidst the chaos of rogue waves, their boat capsised and caught fire, and the two young men doubted they’d make it through the night. 

Thankfully Max and Chris lived to tell the tale, and you can listen to them describe their experiences in this TEDx talk. 

Despite the trauma of the event, Max wanted to give the challenge another go. As Chris was unavailable, Max called on his friend Dave Spelman to join him, and the two signed up for the 2019 event under the name Resilient:X.  

As Max and Dave prepared for the row, Max met Ali Macdonald, CEO of Resilient Nutrition, at an event about resilience. The two immediately got on, and Ali decided to support Resilient:X. To this end, he brought in his pal Greg Potter, CSO of Resilient Nutrition, to help Max and Dave optimise their nutrition and sleep.  

While analysing the nutritional demands of ocean rowing (see this guide for a comprehensive overview of how to fuel ocean rowing), Ali and Greg realised Max and Dave needed a high-calorie, lightweight, health-promoting, performance-enhancing product they could dip in and out of that wouldn’t perish while at sea for several weeks with no fridge. Such a product didn’t exist, so Ali, Greg and Ali’s wife Beth began concocting prototypes of souped-up nut butters that eventually became Long Range Fuel.  

The prototypes were as successful as they could have hoped, and Max and Dave went on to win the pairs race, breaking the World Record as they finished the race in 37 days, 7 h and 54 mins.  

After additional testing and refinements, the turbo nut butters became available to everyone in July 2020. The products have since been used to fuel successful summits of Everest and has been used to break additional World Records and Fastest Known Times in ocean rowing, kayaking, triathlon and ultra running.  

Meanwhile, us non-elite athletes have been using Long Range Fuel as a delicious way of beating brain fog, raising energy and boosting performance during workouts and competitions. 

We originally developed Long Range Fuel to sustain physical and cognitive performance round the clock during self-supported ultra-endurance events, such as ocean rowing, ultra running, ultra cycling, and mountaineering. For this purpose, Long Range Fuel rocks. 

But Long Range fuel shines in other contexts too. 

First, it’s delicious (we’ve lost count of how many people have told us it’s the tastiest nut butter they’ve ever tried), so it can be used in the same ways as any other nut butter. We enjoy using Long Range Fuel as an addition to meals and often add 1 to 2 tbsp of Energise or Energise & Rebuild Long Fuel to breakfast to get in the zone for a tough day at work. Later in the day, some Calm or Calm & Rebuild on rice cakes always goes down a treat, and the positive effects of these two products build over time with regular use. 

Lots of our customers also love using a pouch of Long Range Fuel as a meal replacement, and the Rebuild and Calm & Rebuild products are perfect for this. Unlike many “meal replacement” products, a 100-g pouch of our nut butters contains enough protein and calories to be satisfying. 

To make it easy to know how much of each type of Long Range Fuel to use, we created this Long Range Fuel calculator to give you recommendations tailored to your personal needs. 

Of course!  

We often combine Energise or Energise & Rebuild versions of Long Range Fuel early in the day with Calm or Calm & Rebuild versions later in the day. And we use the Rebuild ones at any time of day. 

Energise or Energise & Rebuild Long Range Fuel: These products are high in caffeine, so limit your intake to no more than 3 g Energise / Energise & Rebuild Long Range Fuel per kg bodyweight per day. 

 Calm or Calm & Rebuild Long Range Fuel: These products contain Ashwagandha, so limit your intake to no more than 2 g Calm / Calm & Rebuild Long Range Fuel per kg bodyweight per day.  

 Rebuild Long Range Fuel: There’s no real need to cap your daily intake, for there’s no caffeine or Ashwagandha in this version. 

All our Energise and Calm products are vegan. 

Terrific news: All our products are fair game for you! 

For several reasons:  

First, this profile is great for the types of athletes we originally developed the product for. Fat contains more calories per gram than carbohydrate. Long Range Fuel therefore contains lots of calories in a lightweight format, which is ideal when you don’t want to carry much. Next, the longer the activity, the lower its intensity and therefore the greater the reliance on fat for energy. And then there’s the fact that athletes who consume more calories in ultra-endurance events tend to finish faster than their peers, so it’s helpful to have products that are calorie dense yet easy to digest. 

We also wanted to create products suitable for the large number of people on low-carb and keto diets. 

Finally, as we discuss elsewhere on our website, the fat in Long Range Fuel is very good for you!  

Sometimes, and this depends on factors such as temperature. Our Keto Coconut & Almond flavour goes particularly firm at low temperatures, so you might need to warm it up a bit - carrying it on your body helps.  

 Regardless, it’s generally a good idea to briefly knead or stir all types of Long Range Fuel before you enjoy them to ensure the textures are consistent. So if you notice a bit of separation in your Long Range Fuel, just mix it back up and you're good to go! 

Keep Long Range Fuel somewhere cool (12 – 20 °C), dark and dry. It’s best to not keep it in the fridge though. 

Long Range Fuel Elite is tested by Informed Sport for the presence of banned substances. This makes it the first, and only, Informed Sport approved nut butter, and gives you confidence that Long Range Fuel only contains what we say it does! 

As we developed Elite Long Range Fuel in collaboration with professional athletes, explorers and the military, the packaging is also slightly different. It comes in lighter-weight pouches that are black and non-reflective. It’s also available in 250-g pouches (email us at humans@resilientnutrition.com for more information). 

As many as 12 to 58% of sports supplements are tainted with low doses of substances banned by the World Anti-Doping Organisation (WADA).  

Not good. 

In response to this problem, the folks at Informed Sport developed a programme that tests products for the presence of banned substances, using a lab accredited to ISO/IEC 17025, a globally recognised standard in test procedures.  

As Long Range Fuel Elite is the first and only Informed Sport approved nut butter, you can rest assured that it contains no such nasties, which is especially important if you get tested for banned substances. This makes it ideal if you’re an elite athlete. 

Absolutely not. 

Palm oil is widely used in nut butters because it’s cheap and helps minimise oil separation. But palm oil is nutrient-poor, unlike other added fats such as almond oil that have positive effects on health. Worse yet, the palm oil industry is contributing to large-scale deforestation and is pushing many species to extinction. 

Basically, palm oil kinda sucks, no matter how people spin the story. 

Environment and sustainability

We do what we can to support the health of the environment. We’re responsible in where and how we source our ingredients, we use recyclable and reusable packaging and we avoid using plastic when possible. 

We respect and value the natural world. We will be donating a fixed proportion of our profits to the Coalition for Rainforest Nations, a charity that helps governments and communities responsibly manage their tropical rainforests. Rainforests are our planet’s richest areas of biodiversity, and preserving rainforests helps protect against climate change. 

 We’re also applying to become a certified B Corporation. 

Delivery boxes and box packaging: these are fully recyclable.  

Long Range Fuel: Long Range Fuel glass jars are fully recyclable. Pouches are recyclable too, but we can’t guarantee that your local authority collects this type of material. As it’s important to us that waste ends up in the right place, we’re planning to release a curbside recyclable pouch. Until then though, we can recycle your pouches with the TerraCycle® Zero Waste Box™ solution. 

How to use Terracycle®: Drop off your used sachets and pouches at a local recycling centre or a TerraCycle® food waste return site (find your nearest site here). Alternatively, return your pouches to us to be sorted, turned into plastic granules, and transformed into new products. Just add a Terracycle Returns Envelope to your cart, and we’ll send you a prepaid returns envelope. Be sure to save up as many sachets and pouches as you can before sending them back to us – at least 20 would be great! 

Good question!  

First, because whey protein is exceptionally high-quality protein (in terms of the gold-standard measure of protein quality, which is based on amino acid composition and digestibility), you don't need that much of it to benefit.  

Next, we understand that dairy farming is in some ways not ideal for the environment. However, we push back against the simplistic notion that animal products aren’t good for the environment. Whey is a byproduct of cheesemaking that would otherwise be discarded, making whey protein MUCH more sustainable than many people realise. In fact, if you’re using whey to replace some of your protein intake from other foods, you might well be reducing your carbon footprint in the process 

For the time being, we’re sticking to using whey protein (sourced locally here in the UK). However, if it the demand for whey ever outstrips the production of whey from cheesemaking, we will switch to developing an alternative protein source that is truly muscle-friendly too… watch this space! 

We hope to get to the high street soon. For now though, the best place to buy is right here on our site!
