Every gram in your pack has to earn its place.
At Marathon des Sables you carry everything. 6 stages, 250km, temperatures up to 50°C. Your food is competing with your sleeping bag, medical kit, and race gear for every gram of pack weight.
Phoenix Bars deliver up to 464 calories per 100g depending on flavour, in a format that will not melt in Saharan heat.
2 to 3 bars per day across 6 stages equals 12 to 18 race bars. Add training bars and you should carry 18 to 24 bars minimum for complete preparation.

What athletes said after
crossing the finish line.
I ate Phoenix Bars every day for lunch, and they were excellent. The taste was great, quite plain in a good way, which meant I did not experience any flavour or palate fatigue, especially compared to other products I was eating at the time. They worked really well for me, and Phoenix Bars will definitely be a staple in my ultra endurance activities moving forward.
Phoenix Bars worked very well for me on the Marathon des Sables this year and I was very pleased I took them.
I used Phoenix Bars on the 2025 Marathon des Sables and these flapjacks were a godsend. High calories to grams, tasty and easy to consume. I used them for my breakfast every day. I will recommend them to anyone doing the MDS in the future.
I used Phoenix Bars during the Marathon Des Sables as my breakfast every day. Their calorie to weight ratio is superb. Highlight was turning a bar into porridge on the rest day. Would not hesitate to recommend Phoenix Bars.
