Used during TransAlba

I used Phoenix Bars during the TransAlba and they were brilliant, easily palatable and doesn't sit heavy on your stomach. Not too sweet either which is a great change from most of the stuff you eat during these events! I will definitely be using them as part of my endurance race setup moving forward.

Melted In My Mouth

My fuelling went well with the Phoenix Bars — they were my main source of solid food for the Spine Sprint. I just broke a bit off in small amounts continuously, right until the end. A welcome change from all the sweeter alternatives and gels.

I also used a full bar as my main fuel source on a Yorkshire 3 Peaks recce the weekend before. It breaks down almost melting in the mouth and got me through 35km of hills with no problem.

A Real Lifesaver at Dukeries 40

Phoenix Bars saved me on the Dukeries 40 run in May – in the early part of the race I struggled to keep my usual fuel down, so I was running on empty at about 25 miles. Then I remembered I had Phoenix Bars in my pack (I bought them off your stall before the race). By dividing it into chunks and gradually nibbling on it, the flapjack gave me all the energy I needed to finish the race.

I have another ultra in a couple of weeks (Tea and Trails Ultra). I will take one bar as part of my fuel for the race and put a spare one in the pack for emergency rations.

They Really Pack a Punch!

I’ve been really impressed with Phoenix Bars. I was originally planning to use one as my emergency food for UTS 100K, but after trying one on a training run, I quickly realised they could be a bit of a game changer – they really pack a punch!

I had a great time at UTS – came 43rd in 17hrs 20, so was well pleased with that. Given the heat on the day, I ended up taking on way more liquid calories than I’d usually like, which caused a few stomach issues. I still managed a couple of Phoenix Bars in the first half though, and they definitely delivered good energy levels.

Chopping them into chunks works really well– made it easier to get them down without relying completely on gels.

I’ll definitely be using them as part of my fuelling going forward and will be recommending them to my mates.

Fuelled our 3 Peaks Challenge

We learnt about Phoenix Bars at Keswick Mountain Festival and picked up a couple of bars before our 10km run. We both felt amazing on them. It’s so hard to fuel a 50–60 minute high-intensity effort on actual food, but the bars gave us a really clean, steady energy—none of that sugary spike-and-crash feeling.

Then, this weekend, we took them on the Three Peaks. It got intense—force 7 winds on Scafell, freezing rain, pitch dark—and the bars absolutely came in clutch. We had nine between four of us over 23 hours and 48 minutes. At our lowest points, they helped reset us—real fuel we could feel working. One of the guys even said, “I might’ve died if not for that guy.”

Honestly, they felt like energy from the inside out—clean, powerful, and exactly what we needed. We’re all big fans now. Thank you!
