DESCRIPTION
Sour blue razz is the one that cuts through when your mouth has had enough of sweet, which happens sooner than most people expect on a long effort. Each packet delivers up to 36g of carbohydrate alongside 170mg of sodium and potassium — fuel and salt together, in a gummy rather than a gel, so there is no sachet to wrestle open with sticky fingers. Two servings per packet, and the guidance is one packet every 30 to 60 minutes. Genuinely easier to eat while moving than anything squeezed from a foil tube.
