The problem

Fuel gets you started. Energy production carries you through all three.

Swim, bike and run each demand more from your energy system. As fatigue builds, power drops, your pace gets harder to hold, and the run off the bike costs more with every kilometre.

  1. Fatigue sets in

    Your legs grow heavier, your effort climbs, and the pace that felt easy on the bike becomes a fight to hold into the run.

  2. Power starts to fade

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

  3. Fuel alone is not enough

    Gels hand you carbohydrate, but your cells still have to turn that fuel into usable energy to keep you moving across three disciplines.

How it works

What each ingredient is there for.

Energy

Swim, bike and run all 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

Three disciplines 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 brick or the race gets tough, magnesium contributes to normal muscle function and to electrolyte balance.

Pre-Activity Shot

I used to fade halfway through the run. Taken about an hour before the start, I finally held my plan across swim, bike and run, and the legs were there when it mattered most.

Frequently asked questions

Take one 60ml shot about one hour before a long session, hard brick or race. On race day, take it before the start. Limit to one shot per day.

No. A gel gives you carbohydrate during the effort. Pre-Activity is taken before you start, and its magnesium, B vitamins and vitamin C contribute to normal energy-yielding metabolism. It works alongside your gels across swim, bike and run 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 swim. It contains no ingredients designed to be taken mid-effort.

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