    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 ultrasoffshore 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.


    Chopped into Chunks:

    Each bar can be chopped into bite-sized pieces for convenient snacking. Perfect for trail ultras, climbing and fastpacking.


    Nutritionally Dense:

    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.


    Robust:

    Built tough for real-world use. Comes in water-resistant packaging that won’t crush or tear. Made for ultras, mountains, the arctic and everything in between.


    Ready to Eat:

    No prep, no waiting. Just open and fuel. Perfect for race-day nutrition, emergency scenarios, or when you simply need calories fast.


    Long Shelf Life:

    Up to 1-year best-before date — great for expedition planning, ultra race drops, or emergency kits.

    Crafted by a BRCGS-certified manufacturer to meet the highest standards in quality, food safety, and performance nutrition — trusted by ultra athletes, mountaineers, and expedition enthusiasts worldwide.

    Used on Marathon Des Sables

    Phoenix Bars worked very well for me on the Marathon Des Sables this year and was very pleased I took them.

    Calorie to weight ratio is superb

    I used Phoenix Bars during the Marathon Des Sables as my breakfast everyday.

    Their calorie to weight ratio is superb.

    Personally took a couple of days to work out how best to use them. Found that if I cut it in half and took half before starting and then nibbled another quarter each subsequent hour that staved off hunger.

    Highlight was turning a bar into porridge on the rest day, was super tasty.

    Wouldn’t hesitate to recommend Phoenix Bars

    Marathon des Sables 2025

    I have been an advocate of Phoenix Bars since their inception.
    This year I was fortunate enough to go to Morocco to take part and complete The Marathon Des Sables .
    Food & nutrition are a major part of a successful event , as such I took 10 phoenix bars with me , I had for breakfast some mornings ( break up into a bag night before ,add a little water and let it soak overnight into a very thick porridge, add a little more water in the morning then either sultanas or Banana chips , amazing breakfast) on the long day I ate 3 bars throughout the day mixed with the 30g Jelly’s from Precision Hydration , this made a fully fuel efficient day.
    Easy to carry , kept their shape even in desert temperatures , break a little off , put in the mouth and gently chew , have a swallow of water snd it’s a massive dose of calories to sustain through the day , easy to digest , easy to swallow , highly recommended.
    Downsides ? Not that I can think of (other than I’d love a Bakewell Tart flavour)
    Thank you Phoenix bars for enabling me to have a successful MDS , I’ll continue to support your company as for me there is nothing else that matches your product .

    Used on Marathon Des Sables Legendary

    I ate Phoenix Bars every day for lunch, and they were excellent. The taste was great - quite plain in a good way - which meant I didn’t experience any flavour or palate fatigue, especially compared to other products I was eating at the time.

    They worked really well for me, and Phoenix Bars will definitely be a staple in my ultra-endurance activities moving forward.
