Real maple, not maltodextrin
Maple sugar is sucrose, which is glucose and fructose in equal parts. No maltodextrin anywhere in the range.
Two sugars, one syrup
Glucose and fructose in a 1:1 ratio, as they occur in maple. Why that matters, with sources, is on the science page.
Citrate, not chloride
Sodium and potassium as citrates rather than as table salt: 190 mg sodium and 125 mg potassium per gel. The reasoning, and its limits, are on the science page.
26 grams, every 20 to 30 minutes
One gel, one interval. Small and repeated rather than one large dose. Plan the count with the Fuel Guide.
Three ingredients
Maple syrup, sodium citrate, potassium citrate. That is the whole label.
  1. Start fuelling earlyTake your first gel within the first 20 to 30 minutes, before you feel like you need it.
  2. Then every 20 to 30 minutes26 grams at a time, on a steady schedule. The Fuel Guide sets the number for your event.
  3. Always with waterThe gel carries carbohydrate and electrolytes, not fluid. Drink alongside it.
  4. Rehearse it in trainingDo not run a new fuelling plan for the first time on race day.

Why we built it

Ingredients you want. A formula that performs.

Ingredients you want

Maple syrup, sodium citrate, potassium citrate. That is the base gel, and every amount is printed on the label.

A formula that performs

26 g of carbohydrate, 190 mg of sodium and 125 mg of potassium in every gel. One every 20 to 30 minutes, all the way to the finish.

We ran marathons on this before we sold it. We went through nearly every gel on the market, then started mixing our own because none of them did both. It stayed between us for a year. Read how Sève started

Why 26 grams

One gel is 26 g of carbohydrate. One every 20 to 30 minutes works out to 52 to 78 g an hour, inside the 30 to 90 g per hour our Fuel Guide plans around. The guide sets the number for your event.

The full list

What's inside

Three ingredients. No proprietary blends, and no natural flavours standing in for a list of things.

  • Maple syrup Pure Québec maple. The carbohydrate, and most of the character.
  • Sodium citrate 190 mg sodium (as citrate). We chose citrate over a chloride salt. The reasoning, and its limits, are on the science page.
  • Potassium citrate 125 mg potassium (as citrate). The second electrolyte, alongside sodium.

Frequently asked questions

No. Flow is caffeine-free, so it suits daily training and any time of day.
Yes. All Sève gels are plant-based and gluten-free.
Yes. The gel supplies carbohydrate and electrolytes, not fluid, so drink water alongside it.
One every 20 to 30 minutes is the intended rate. For sessions over about 90 minutes, plan the number in advance rather than improvising.
Room temperature, out of direct sun. Maple is stable, so they travel well in a jersey pocket or a race belt.
