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:

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.

Game Changer

I’m incredibly cautious of what I put into my body, especially on long hikes.

I’m usually the girl with a freezer full of homemade, natural ingredient protein bars that has everyone on the trails asking for recipes.

Phoenix Bars were a game changer on my recent trip to Brazil! Gut-friendly, high-energy flapjacks that travel well and won’t melt in hot climates! Yes please!!

99% of protein bars on the market don’t agree with my gut at all and I had no issues with Phoenix bars…they’ll be well trusted on the trails!

These are already on my essentials backpacking list for the Alps! 🏔️

These bars are great!

I ordered Phoenix Bars for GB Ultra's Hope Trails event and, despite the heat, I managed to get to 100 miles so I’m really happy.

The bars are great! I alternated between fruit and food at the aid station and then a few bites of the bar at the start line area and that seemed to work really well. They were so easy to eat on the go and break bits off without it completely breaking and taste good. I think it’s the first longer race I’ve done where I didn’t have any fuelling issues so they definitely worked (and I’ve got a few extra to keep me going!). I’ll definitely use them again! Thank you!

Rocket Fuel

All I can say is Phoenix Bars are rocket fuel.

If you’re feeling low on energy and gels and other things just aren’t going in or you can’t drink anymore calories, break out a Phoenix Bar, eat half, then set your watch for 25 minutes, then eat the other half.

I did this at the Tea & Trails ultra and I was like a different person.

Fuelled my 500km in 10 Days Challenge

I purchased 30 Phoenix Bars to help my hit my 6,000 calories per day target. They worked really well and allowed me to complete my challenge - I particularly enjoy their taste and that they are so easy to digest. I would like to undertake more challenges like this in the future and I would be very keen to use these bars again.
