“I used to fade after 30k. This block I finally ran the negative split I had been chasing, and the legs were there from km 1 to 42.”Sophie Laurent, Lyon, France “Taken about an hour before my long run, the pace that used to break me held to the end.”Luca Bianchi, Bologna, Italy “A friend told me to just try it once. I signed up for my first marathon terrified of the wall, and I ran it all the way out to the line.”Thomas Vermeer, Utrecht, Netherlands “First long race where the last 10k did not fall apart. I finished strong instead of surviving.”Nina Andersen, Aarhus, Denmark “Nothing sitting heavy. I take it before I run and my stomach finally agrees.”Anna Müller, Freiburg, Germany “The big weeks used to leave me wrecked. Now I hold my effort and keep showing up.”Emma Collins, Bristol, England

The problem

Fuel gets you started. Energy production keeps you moving.

Long efforts demand more from your energy system. As fatigue builds, power drops, pace becomes harder to maintain, and every kilometre costs more.

  1. Fatigue sets in

    Your legs grow heavier, your effort rises, and the pace that felt comfortable becomes harder to hold.

  2. Power starts to fade

    As the session gets tougher, your output drops and your body begins slowing down before the finish.

  3. Fuel alone is not enough

    Gels provide carbohydrates, but your cells still need to turn that fuel into usable energy to keep you performing.

How it works

What each ingredient is there for.

Energy

Big efforts demand more from your energy system. B vitamins and vitamin C contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue.

Focus

Long sessions test your focus as much as your legs. The caffeine from guarana helps increase alertness and improve concentration. High caffeine content. Not recommended for children or pregnant or breastfeeding women.

Muscles

When the session or race gets tough, magnesium contributes to normal muscle function and to electrolyte balance.

Frequently asked questions

Take one shot about one hour before a long run, hard session, or race. Limit to one shot per day.

No. A gel gives you carbohydrate during the run. Pre-Activity is taken before you run, and its magnesium, B vitamins and vitamin C contribute to normal energy-yielding metabolism. It works alongside your gels rather than replacing them.

One 60ml shot with olive leaf extract (100mg oleuropein), caffeine from guarana (80mg), L-citrulline, acetyl-L-carnitine, magnesium, and B and C vitamins. Neutral flavour with a hint of blueberry and a mild bitterness from the olive leaf extract. Best served chilled.

High caffeine content. Not recommended for children or pregnant or breastfeeding women. A food supplement is not a substitute for a varied, balanced diet and a healthy lifestyle.

You take it about an hour before you start, not during, so it sits well ahead of the effort. It contains no ingredients designed to be taken mid-run.

Every batch is lab-tested, and every dose is on the label.

Yes. You can pause, skip a delivery, or cancel anytime from your account. No minimum term, no questions asked.

We ship across Europe from our warehouse, with orders dispatched within 24 hours. Shipping is free.
