Phoenix Bars worked very well for me on the Marathon Des Sables this year and was very pleased I took them.
I used Phoenix Bars during the Marathon Des Sables as my breakfast everyday.
Their calorie to weight ratio is superb.
Personally took a couple of days to work out how best to use them. Found that if I cut it in half and took half before starting and then nibbled another quarter each subsequent hour that staved off hunger.
Highlight was turning a bar into porridge on the rest day, was super tasty.
Wouldn’t hesitate to recommend Phoenix Bars
Fueled me perfectly ready for my mile race, before warm up and after, easy to eat and tasty!
I have been an advocate of Phoenix Bars since their inception.
This year I was fortunate enough to go to Morocco to take part and complete The Marathon Des Sables .
Food & nutrition are a major part of a successful event , as such I took 10 phoenix bars with me , I had for breakfast some mornings ( break up into a bag night before ,add a little water and let it soak overnight into a very thick porridge, add a little more water in the morning then either sultanas or Banana chips , amazing breakfast) on the long day I ate 3 bars throughout the day mixed with the 30g Jelly’s from Precision Hydration , this made a fully fuel efficient day.
Easy to carry , kept their shape even in desert temperatures , break a little off , put in the mouth and gently chew , have a swallow of water snd it’s a massive dose of calories to sustain through the day , easy to digest , easy to swallow , highly recommended.
Downsides ? Not that I can think of (other than I’d love a Bakewell Tart flavour)
Thank you Phoenix bars for enabling me to have a successful MDS , I’ll continue to support your company as for me there is nothing else that matches your product .
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 didn’t 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.
