Introducing Phoenix Bars
Phoenix Bars are high-calorie, highly compact, and lightweight flapjacks meticulously crafted to fuel your toughest expeditions, mountaineering challenges and ultra-endurance races. Whether you're ski touring, undertaking a high-altitude expedition, or pounding out miles as an ultra runner, these bars deliver substantial, sustained energy in a form that’s ready to go, wherever you go.
552 Calories per Bar:
A calorie-dense energy bar, each Phoenix Bar delivers a powerful 552 calories. Perfect for long, cold days trekking, fastpacking, or during unsupported polar expeditions — giving you compact, portable fuel that lasts from checkpoint to summit.
Highly Compact, Lightweight & Portable:
Minimal bulk, maximum energy. Designed to help you save weight and space whilst trekking, mountaineering and during ultra-endurance events - where every gram counts.
66g of Carbohydrates:
Phoenix Bars are high in carbohydrates - delivering a strategic mix of fast- and slow-release carbs to power multi-day adventures, trail ultras, and high-altitude expeditions — keeping your energy steady through big days and long nights.
Versatile: Can Be Made into Porridge or Smoothie:
Add water or milk (hot or cold) to turn your bar into a warm porridge or quick recovery smoothie. A flexible, adaptable food source for ultra-endurance fuelling.
Easily Digestible:
100% vegan, gluten-free, and GMO-free. Built for easy digestion in high-output scenarios and at altitude, with gut-friendly ingredients that minimise risk of digestive issues — essential for ultra runners and expedition enthusiasts alike.
Easy-To-Eat & Open:
Soft texture that melts in your mouth — easy to eat even with gloves or in sub-zero conditions. Ideal for fuelling on the move.
Tasty Without Being Sickly Sweet:
Light vanilla flavour means no palate fatigue, no sugar crash. Ideal for ultras, offshore sailing, multi-day adventures, or continuous efforts when over-sweetened snacks become unappealing.
Natural Ingredients:
Made from real, whole ingredients like gluten-free oats, coconut oil, pea and soy protein, and plant-based nutrients.
Climate-Resilient:
Won’t freeze in sub-zero temperatures or melt in extreme heat. Built for polar regions, ski touring, ski mountaineering, desert crossings, and jungle heat — a climate-proof energy bar for every type of extreme environment.
18g of Protein:
Supports muscle maintenance and recovery during and after high-output efforts. Essential for ultra-endurance races, military personnel and multi-day expeditions.

Packed with 8 essential vitamins and minerals — including iron, manganese, phosphorus, and B vitamins — plus MCTs from coconut oil for steady, sustained energy.
Altitude Optimised:
Formulated with nutrients that support performance at high-altitude climbing and mountaineering, including iron, vitamin E, B1, and B7 — helping oxygen delivery and energy regulation in thin air.
Sustainable:
Vegan, palm oil-free, and ethically produced with biodegradable packaging and eco-conscious shipping options — perfect for the sustainably-minded adventurer or eco-conscious ultra runners.
Gluten-Free & Vegan:
Ideal for coeliacs, plant-based athletes, and mixed dietary groups — no compromises on performance or inclusivity.

Brilliant product that delivers everything it says it is going to. Super tasty, easy to eat, long lasting performance and now my go-to bar. It’s hard to know what else to say other than try it if you haven’t yet given it a go. Perfect.
Great product, my favourite in the market. Speedy delivery
I’ve been using the Phoenix bar now for the last year in preparation for a couple of endurance events. I must say, once you try it, you’ll never go back…
The bar has completely changed my preparation and performance, giving me a long lasting energy boost at no expense of taste. It is super transportable and lasts very well in backpacks, keeping its shape and consistency.
Unlike other products, the Pheonix bar ticks all the boxes and provides me with the macros and nutrients required to sustain and perform under intense strain.
As a side note, James was excellent during the sales process, giving timely updates on delivery and stock. His personal note in my first batch was a nice touch and you really feel appreciated and part of the team.
Best of luck with this product, I genuinely hope it goes on to do great things and reach all those in need. The benefit it adds seriously changes the game and this could help a lot of people achieve the results they’re after.
I bought Phoenix Bars as I needed their substantial calorie count for the Grand Union Canal Race (which I ran self-supported). I find they digest easily, are moist enough, taste good, and can be easily cut into thirds to eat every 20 minutes.
My Garmin watch said I burned nearly 16,000 calories over the 38 hours I ran — so I definitely needed the calories, and I was pleased to finish 15th.
I’m keen to use Phoenix Bars again for the long races I have coming up.
I was very pleased with the Phoenix Bars I ordered. They are not overly sweet, aren't sticky and seem easy to digest, suitable for the ultra distances that I am doing.
