High-Calorie Protein Bars for Endurance, Expeditions, Low Appetite and Weight Gain Big calories. Small bar.

I have used Phoenix bars on several events including deep arctic cross-country ski-ing in -35 degrees, and on a recent event in upstate NY is relative balmy 20 degrees. The Phoenix bars are easy to eat and get down without the hassles of dry mouth syndrome when eating on the hoof as one experiences with many other foods. Gels have never worked for me. I love the ease of eating these, and the easy digestion and consistent energy. I actually made porridge for breakfast one morning with the chocolate bar and was really enjoyable and easy to make with a little hot water. Excellent product James - well done

Between us we took a selection of these bars on The Long Crossing of the Lofoten Islands which is about 150 miles north of the Arctic Circle and has some pretty remote sections with plenty of wild camping.
We have tried other energy sources for our endurance treks and thought we would take these as a safety back-up in case we couldn't resupply as planned and/or for those longer days where you just need to make a final push before stopping for the night.
We were all genuinely pleasantly surprised by the range of flavours and the texture of the bars which made eating and digesting them a breeze without any sickly sweet aftertaste. We didn't make them into porridge and tbh the bars were pretty crumbly after being bashed around in our rucksacks for a while but that was no drama at all. The bars were sufficient to fill us up, provide a steady source of energy and improved morale no end during some pretty testing weather!
The chocolate and salted caramel flavours were top choices amongst the team. Phoenix Bars will definitely feature on future expeditions!

It’s made from real high quality ingredients including real fruit, and isn’t overly sweet like many other protein/energy bars. It’s also vegan, gluten-free and dairy-free, which makes it really easy to keep down, especially when you’re already overloaded with sickly sweet gels and your body just can’t handle anything too rich.

I’m a full marathoner, and the whole bar was probably a little too much to eat during the race, but it was still really helpful for refuelling. I had about half of it bit by bit during the race, then ate the rest as a recovery food. I’d love to see the product range expand in the future, and a smaller portion version would be great too.

used two vanilla bars during the Yorkshire Three Peaks training run with my dog — officially 24 miles with 5,250 feet of ascent, though my Garmin recorded 6,490 feet? I broke each bar into around six pieces and ate them throughout the round.
They were easy to eat, didn’t clog my mouth, and I wasn’t left spitting out dry food — a real plus compared with other bars that can be too dry. I also had no stomach discomfort while running or trotting, and they didn’t put me off taking more fuel on the hour.
My energy levels felt steady throughout, with no dips or crashes that needed a quick sugar hit — which often leads to more lows later. Overall, I only used the two bars, one energy gel for the final push up Ingleborough, and about two litres of water across four bottles, each with half an electrolyte tablet. The rest of my food stayed untouched, which was excellent.
In summary, the big win was steady energy over the full 5 hours 51 minutes steady training run and a few seconds. A great result.

Using on the Yukon 1000 10th July 2026, we’ve trialed them for several long sessions and they really do work and give you plenty of extra energy.Very happy team YOY Richard & Rob

Very happy with flaming Phoenix, I bought them to help me on my ultra runs & I work as a lorry driver. They also help me stop buying service station food. They are very easy to eat as a bar, no problems with digestion. The range of flavours is excellent. I would buy again.

Flaming Phoenix Bars featured as a star in my food supply for my recent South Pole expedition! Easy to eat, even at -45c. Apple and cinnamon was a particular standout.

I successfully used Phoenix Bars as part of my fuelling strategy for the Winter Spine Challenger South. Reliable, easily eaten and most crucially for me, tasty and palatable especially towards the end of the race where yo finds it hard to eat. I ate the bars slowly by breaking them down into chunks and consumed a couple every 30 minutes.

Crucially for this race where the temperature was around or below freezing, the bars remained soft enough to eat unlike some other food that I had that was too hard to eat!

I would definitely recommend Phoenix Bars as part of a fuelling strategy for any ultra and will be using them myself again in future on my next race.

Used these bars when bike packing across Vancouver island. Didn't break up in my bag, and could snack on them as needed to top-up my energy rather than having more super sweet gels or other energy bars. Life Saver.

I’m incredibly cautious of what I put into my body, especially on long hikes.

I’m usually the girl with a freezer full of homemade, natural ingredient protein bars that has everyone on the trails asking for recipes.

Phoenix Bars were a game changer on my recent trip to Brazil! Gut-friendly, high-energy flapjacks that travel well and won’t melt in hot climates! Yes please!!

99% of protein bars on the market don’t agree with my gut at all and I had no issues with Phoenix bars…they’ll be well trusted on the trails!

These are already on my essentials backpacking list for the Alps! 🏔️

Recently used phoenix bars on a trail marathon training run with massive vertical gain, we were out for 6 hours I took only two of these with me, digest really well, and kept my energy up despite the 25⁰c weather, have already recommended them to my coaches athletes and friends

I was lucky enough to be given a few of these bars as a trial however unfortunately due to injury I have been unable to test them. I managed a 180km cycle through the hills of Dorset and took along this weapon of a bar.
I nibbled on these throughout the day without any expectation and wow!! My energy levels did not disappoint. These kept me energised and comfortable right to the end.
Definitely my new endurance bar of choice.

I’m so pleased to have come across the Phoenix Bars for my mountain ultramarathon training. These bars are great for snacking on throughout and I’ve found them to be the best way of keeping on top of my calorie intake. I highly recommend these bars for ultramarathon runners.

Great tasting flapjacks with a high amount of carbs. Recently used them on a 42 mile fast pack across the Brecon Beacons and they delivered what I needed. I will be ordering them again.

I tried Phoenix Bars as I’m training for a 170km UTMB. I'm really impressed by the flapjacks’ ultra-high-carb content and I enjoyed mixing them with water to make a nutritious porridge for breakfast.

I really liked the Phoenix Bars I bought - the texture is very good and they certainly provided me with an energy boost. They worked really well broken off into little chunks.

I recently had the pleasure of trying the Flaming Phoenix Bar, and I must say, it's an outstanding addition to my endurance nutrition lineup.

One of the first things I noticed was how easy it is to see the calorie count and the breakdown of proteins and carbs on the packaging. This transparency is essential for anyone needing to carefully monitor their intake during intense activities.

The Phoenix Bar is not only easy to eat but also not too stodgy, making it perfect for consuming on the go. It breaks off conveniently into chunks, allowing for quick, mess-free snacking.

Taste-wise, it’s a winner. The flavor is something I genuinely look forward to during long, slow endurance events like Atlantic row crossings, south pole expeditions, mountaineering, ultra triathlons, marathons and hikes. It's a delightful treat that keeps me motivated.

What really sets the Phoenix Bar apart is its versatility. I even mixed it with water to create a porridge-like consistency in a reusable nutrition bottle for my bike rides. This method worked incredibly well, providing a moist, easy-to-consume option that didn’t crumble. It was almost game-changing for my nutrition strategy.

The Flaming Phoenix Bar is a fantastic product that meets all the needs of an endurance athlete. Its great flavor, ease of consumption, and nutrient profile make it a must-have in your nutritional arsenal. Highly recommended!

I have used these bars for multi day ultra running events. They are the most calorie per weight I could find, so they helped to reduce the weight of my running pack but still allowed me to carry enough supplies . The flavours are nice also.

The Flaming Phoenix bars have now become the standard food for my long fell runs (15+ miles). They fuel exceptionally well, cause no issues and reduce the amount of food I need to carry. Well worth the investment.

I'm really impressed with the bars. Had 3 of them while I was out running 22 miles and no spikes at all. When I've used gels before I've had bad spikes.

I bought Phoenix Bars because of their high energy to fuel my walk up Mount Snowden. They worked well for me and I think they are a great product!
