What ultra and adventure athletes say
“A real game changer for Ultra runs. Easy to chew and swallow on the move and easy on the stomach.”
“On a multi-day running adventure in the dolomites. These were the perfect energy pastilles, easy to eat and get down on the move. The daily pouch getting refilled from the larger pack was perfect.”
“Used these to fuel my training and ultra. Love that there is less plastic waste and no food wastage as you just pop in what you need out of the bag.”
“Smashed through my pastilles on a recent, very tough mountain bike Audax… No bonk and tasted lush.”
