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.

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.

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.

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