These bars are unreal! My biggest nemesis has always been fuelling properly for long ultra-marathons and these are definitely going to help!
Thank you to James and Flaming Phoenix for the usual 5 star service ⭐️
I used Phoenix Bars on Beyond the Ultimate's Desert ultra and during a 100 miler. I like chopping Phoenix Bars into bite-sized chunks for easy snacking and I find the new recipe much easier to eat and less crumbly. I am excited to try the new flavours as I think this helps to add more variety.
Phoenix bars helped me to consume more calories during treatment for my medical condition. They are low volume, weren't too sweet, easy to digest and I also liked that they can be made into porridge.
I used Phoenix Bars during the Cheviot Goat and they were delicious! The flavour was amazing and it helped me pack in those essential calories and carbs for the border ridge on the way to the Cheviot.
I’ve been telling everyone since the race how brilliant they were and I can’t wait to book my next adventure so I can order some more 👍🏻
I have been using phoenix bars for the last few months and I really like them. They provide so much energy in a small portion and I'll be using these again for the Spine - both as a bar and as a porridge.
