What Is 6AM RUN Pure Sprint, and Who Is It For?

We put pure sprint through a month-long field test to see if this pre-sprint supplement delivers measurable speed improvements.

Updated 7 Aug 2026 3 min read 7 sections

6AM RUN Pure Sprint is the brand’s pre-workout drink for sprint, cardio and conditioning sessions, sold on its site as Sprint, an “immediate boost” for cardio and conditioning. It is aimed at people who do short, hard efforts such as sprints, hill repeats and intervals, rather than easy runs. What it contains, and how much to take, is on the label, and anyone with a health condition or on medicines should check with a doctor or pharmacist before using any pre-workout.

What is 6AM RUN Pure Sprint?

6AM RUN is a running-focused supplement brand. 6AM RUN Sprint is its product for cardio and conditioning, and the name “Pure Sprint” is how many people search for it. On the brand’s site it is one product page, so if you see “Sprint”, “Pure Sprint” or “Sprint Cardio” in articles, they usually mean the same drink.

Pre-workouts built for short, hard efforts often contain caffeine, beta-alanine or citrulline malate. We do not list the exact formula here, because the label is the only reliable source and formulas can change. Check the ingredient panel on the product page before you buy, and look for the caffeine amount in particular.

Who Pure Sprint is for

Based on how the brand describes it, Pure Sprint is aimed at:

Runners who add sprint work, strides or hill repeats to their week.
People who do interval or conditioning sessions.
Team-sport players who train with short, repeated bursts.

It is less of a fit if your training is mostly easy, steady running. A stimulant drink before an easy jog adds caffeine without a clear reason. It is also not a fit for anyone who has been told to avoid caffeine.

Does Pure Sprint actually improve speed?

We cannot promise that it will. We have no source showing what this product does for speed, and we do not repeat claims about reaction time, power output or lactate buffering without one. Many things decide how fast you run: training, sleep, food, warm-up and sprint mechanics. A drink does not replace any of them.

If you are thinking about a pre-workout mainly to improve performance, a coach can help with the training side, and a doctor or sports dietitian can tell you whether a caffeine-based product suits you.

How to read the label

Label item	What to check
Caffeine	The amount per serving. Add it to your coffee, tea, energy drinks and any other pre-workout.
Other actives	Ingredients such as beta-alanine or citrulline malate, and their amounts.
Blends	A proprietary blend hides the amount of each ingredient.
Directions	Serving size, how much water to mix it with and when the brand says to take it.
Warnings	Who should not use it, including any note on pregnancy, age or health conditions.
Sport testing	If you compete under anti-doping rules, look for a third-party certification and check your organisation’s rules yourself.

How to use it safely

Follow the directions on the label for how much to take and when. We do not give our own serving or timing plan. A few practical points apply to any caffeine-based pre-workout:

Do not stack caffeine. Skip other caffeine sources on the same day unless you have checked your total with a pharmacist.
Mind your sleep. Stimulants taken late in the day can affect sleep. If you train in the evening, ask whether a stimulant-free option makes more sense.
Expect some ingredients to have side effects. Beta-alanine, if the product contains it, is known for causing a tingling feeling in some people. If anything worries you, stop and ask your doctor.
Stop if something feels wrong. A racing heart, chest pain, dizziness or feeling faint during training means stop and get medical help.

Who should check with a doctor or pharmacist first

Please talk to a doctor or pharmacist before using Pure Sprint, or any pre-workout, if you:

Have a heart condition, high blood pressure, an anxiety disorder or trouble sleeping.
Take any prescription medicine, including medicines for mood, attention or blood pressure.
Are pregnant or breastfeeding.
Are under eighteen.
Are sensitive to caffeine or have been told to limit it.

Bring the label, or a photo of it, so they can check every ingredient.
