    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.


    Made in the UK:

    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 for London Marathon

    I ate Phoenix Bars immediately post-marathon to keep me from crashing out, and at another the following to refill my glycogen. Thought they were brilliant at fuelling me - definitely helped to prolong the time before the inevitable crash last night. Easily eaten and digested and was perfect as a recovery fuel. Would have been interested to see how they helped my carb loading pre-race but hasn’t practiced with them and didn’t want to try anything new before the day. Love the fact that they’re pretty big as well - there’s a sort of mental factor there that your brain feels like you’ve refuelled well, regardless of what the calories might be (compared to some bars which can be finished in 2 bites).

    Really Enjoyed Them

    I took Phoenix Bars on the MDS and I thought they were really good. They didn't melt in the heat and I am keen to use them again on my next ultra-endurance challenges.

    Very Nutritionally Dense

    The calorie-density of Phoenix Bars suits my nutritional needs very well and I think they would be particularly helpful for early morning races. I really like how they can be made into a nutritionally dense porridge and I would be keen to order some more for the Dragons Back.

    First try

    So I bought 5 of these bars a few weeks ago and thought I’d try one. First impressions, I love the taste and texture. Certainly tastier than any I’ve tasted previously..
