Phoenix Bars have been permanently refined to be moister, easier to eat and more robust - whilst still preserving every specialised feature that makes them the bespoke choice of fuel for extreme expeditions and ultra-endurance challenges.
Our High-Calorie Bars
Phoenix Bars are high-calorie, highly compact, and lightweight flapjacks meticulously crafted to fuel your toughest mountaineering expeditions 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 in the mountains, 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.
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.
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.

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.

Phoenix Bars deliver exactly what you need on long training sessions and expeditions, great taste, high energy, and an impressive nutrition profile. I’ve found them easy to eat on the move and really effective for keeping energy levels steady. A brilliant product from a new company with huge potential. Highly recommend!
I used Phoenix Bars for my first 58km ultra and they worked really well for me. I think they are a great product.
I ordered (and re-ordered) Phoenix Bars for Rat Race's 100 mile adventure race in Scotland and they worked really well. They were particularly useful for helping to meet the mandatory kit requirements of carrying 1000 emergency calories.
I'm enjoying Phoenix Bars and I plan to use them on the Cheviot Goat and the Spine Challenger North.
I used Phoenix Bars at the recent ultra I ran and they were great. It was the Seven Sisters Skyline Ultra where I placed very well and I feel your product helped fuel me perfectly throughout. I very much prefer eating actual food rather than just gels!
I am looking forward to using these more regularly in my training and at races.
