Carbs in the gel, electrolytes in the bottle, CoreCtrl for the hottest races. Start with the gels; build from there.

Low Salt for normal sweat. Salt marks on your clothes or extreme heat? Replace Low Salt with High Salt. Mix the two to set your hour. 2 gels an hour = 80g carbs. Need more? 2 Low + 1 High = 120g carbs and about 580mg sodium.

03 / The problem

Energy Gel · 40g carbohydrate
  1. Gels 1 and 2

    Most gels: Most gels are built for the first hour. truefuels: 40g of carbs and the salt you need, in one gel.

  2. Gels 3 and 4

    Most gels: Too sweet, too thick. truefuels: Thinner than most gels.

    By the third, the sweetness and the thickness are what you remember, not the carbs.

  3. Gels 5 and 6

    Most gels: A stomach that votes against the plan. truefuels: Gel six tastes like gel one.

    Mild, with a hint of salt.

“Most gels I just can’t stomach, 2 is my limit, but these are no problem at all.”

    07 / Questions

    Questions before your first box.

    Which gel do I use?

    Low Salt for normal sweat. Salt marks on your clothes or extreme heat? Replace Low Salt with High Salt. Mix the two to set your hour.

    I’m switching from Maurten, SiS or Precision. How do I start?

    Swap like for like on 40g, then use your long sessions to test before race day.

    Will it be too sweet?

    Reviewers call it mild and “not too sweet”. There’s no added flavour to fight at hour four.

    Do I still need electrolytes?

    The gels carry salt already. Heavy or salty sweaters add one Electrolytes sachet per bottle.

    What does it cost per long run?

    Two gels: £5.99 one-time, £4.19 on the Flexible Plan.

    How fast is delivery?

    Delivery to the UK: 1 to 3 working days, free over £40, otherwise the fee shows at checkout.

    How do I open it on the bike?

    Tear from the notch, one-handed.

    “… Finished 4th in V40 female category and 30th overall and had no tummy issues.”
