What does it do?

Prerun works by preparing your body before the run actually starts, not halfway through it.

Naturally sourced caffeine helps you feel alert, focused, and ready to move, without the jittery spike or crash you get from coffee. Beta-alanine and citrulline support blood flow and fatigue resistance, making it easier to settle into your pace and hold it without that heavy-leg feeling creeping in too early. Electrolytes replace what you’ll sweat out, helping you stay steady rather than fading as the run goes on.

The result is simple.
You feel more prepared. More willing. More comfortable.

On days motivation is low, it helps you get out the door. Once you’re moving, your run feels smoother, more controlled, and easier to manage.

It didn’t exist. So we built it.

Runners had gels, electrolytes, and carb drinks - but nothing designed to prepare the body and mind before the run even starts.

Prerun was created to fuel that moment.
With science-backed ingredients that support energy, focus, and endurance - without the crash, the clutter, or the guesswork.

One simple ritual.
One clear purpose.

Instructions

Mix 2 level teaspoons with 250ml of cold water. Shake or stir, leave it for 5 minutes to fully dissolve and then drink it 15 minutes before your run.

The amount of water you use will affect the taste, so experiment and see what works best for you. If it’s cold outside, try adding hot water.
