★★★★★"Phoenix Bars pack a lot of calories into such a small bar, which makes it easier to eat during ultra marathons."Amy Earlam · 200-mile race

★★★★★"Low volume, not too sweet and easy to digest. I also liked that they can be made into porridge."Verified customer · When eating felt hard
What I built Phoenix Bars to replace
Most sports nutrition was built for short, intense bursts. Phoenix Bars were built for the opposite. Long efforts, extreme environments, and situations where eating is hard.

Why I built Phoenix Bars
Hi, I'm James.
I started Phoenix Bars at 23 after 150 conversations with ultra endurance athletes, extreme adventurers and people who struggle to eat enough calories.
Every design choice came directly from one of those conversations.
I'm obsessed with Phoenix Bars being the single best specialist product on earth for people who need to maximise their calorie intake when something is making eating difficult.
I pack every order from my home in Surrey, and I reply to every email myself, usually the same day.
"I use Phoenix Bars between breakfast and dinner. They keep me full and energised, and one bar sees me through the whole day."

Made in the UK in small batches. Hand-packed by James in Surrey. Used at Marathon des Sables, the South Pole, and in everyday situations where food feels hard.

Every Feature, Explained
Tap any benefit for the story behind it.
Up to 557 Calories Per Bar:
A calorie-dense energy bar, each Phoenix Bar delivers up to a substantial 557 calories per bar.
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.
Up to 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.
Can Be Made into Porridge or Smoothie:
Add water or milk (hot or cold) to turn your bar into a nutritious warm porridge or quick recovery smoothie. This approach can be particularly useful during endurance activities and expeditions, where compact, calorie-dense nutrition is important and eating full meals may be impractical.
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.
Tasty Without Being Sickly Sweet:
Six delicious, neutral flavour options - preventing flavour and palate fatigue. Ideal for ultras, offshore sailing, multi-day adventures, or continuous efforts when over-sweetened snacks become unappealing.
James's note"Not sickly sweet" was the single most-requested change in my 150 pre-launch conversations with ultra athletes. We landed on six neutral flavours so you can rotate through a long effort without getting palate fatigue.
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.
James's noteThese have been used at the South Pole at minus 45 and across the Marathon des Sables in 50-degree desert heat. The recipe is built to hold its texture either side of that range.
Up to 19g 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.
8 Vitamins & Minerals:
Packed with 8 essential, naturally occurring 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 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 2-year best-before date — great for expedition planning, ultra race drops, or emergency kits.
Made in the UK:
Hand-crafted by an experienced manufacturer to meet the highest standards in quality, food safety, and performance nutrition - trusted by ultra athletes, mountaineers, and expedition enthusiasts worldwide.
James's noteI drive up to the factory whenever batches are being made. Worth the trip to be in the room. Every order then gets hand-packed by me from home in Surrey.
