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.

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.

Used on UTS

I used Phoenix Bars during UTS and they were were great - really tasty and easy to nibble on whilst climbing. I'd definitely use again and will take with me for Lakeland 50 miler in July

Used on The Lap

I purchased two Phoenix Bars for the Lap ultramarathon because they met all the criteria on paper of being a very high-calorie and high-carb solution and they certainly delivered. Two Phoenix Bars and Tailwind got me through the race. I really love the convenience these bars offer I’m definitely keen to use them again.

Re-Ordered

I reordered Phoenix Bars after using them last year during my Ultra training and during Ultra X England 110. They tasted amazing and were a nice and easy way to get my carb intake up.

I’m planning on using them this weekend during a 70 mile Ultra.

After using the bars previously and with how well they worked they were an obvious choice for my next event.

Tasty, Calorie-dense & Compact

People often ask me about my fieldwork kit - what gear, what food, what gets me through long days in the mountains. So I wanted to start by sharing something that’s become a small but essential part of my routine: Phoenix Bars.

I came across them a few months ago and wasn’t expecting much. I’d been cycling through protein bars and mixed nuts. But Phoenix Bars honestly surprised me. They’re these extremely calorie-dense flapjacks (552-calories per bar) that taste incredible. Just sweet enough to enjoy, but not cloying. And that matters more than you'd think—when you're cold, tired, and wet, the last thing you want is something synthetic or overly sugary.

Nutrition-wise, they’re exactly what I need—enough protein and proper calories to keep me going without the crash. They’re also really compact, shelf-stable, and easy to pack in just about any pocket.

But what really made me want to keep supporting them is the team behind it. James and the people at Flaming Phoenix actually care. They listen, take feedback seriously, and you can feel that they’re trying to build the best product they can. They connect with their customers.

I actually keep two on me at all times now. Whether I’m in the hills or halfway through a long day of back-to-back meetings, they’re my go-to. It’s a small thing, but it makes a difference.

Support small businesses. Eat better snacks

Keswick Mountain Festival

I had one Phoenix Bar as my breakfast before starting the 50km, and I have to say I was really impressed. The flavour was great, and I was genuinely surprised by how easy it was to eat and how light it felt on my stomach — no bloating or discomfort at all
