For the athlete on your list

Give a Sweat Test this year

Every runner, rider and triathlete you know has guessed at their electrolytes. A Starter Kit gives them their own number: they test during a normal workout, mail the sample back, and their first pouch ships at their Level.

Ship it to them at checkout. They test whenever it fits their training.

How it works

How the Sweat Test works

You test during a normal training session. Wear the patch, mail it back, and get your Level.

  1. Order

    Your kit ships

    Sweat patch, collection vial, tweezers, prep pads, instructions and a prepaid return mailer (US).

  2. Test day

    Train as usual

    Wear the patch on your forearm for 30 to 60 minutes of a normal session. Weigh in before and after and note what you drink, so the lab can work out your sweat rate.

  3. After your session

    Mail it back

    Move the gauze into the vial with the tweezers and send it back in the prepaid mailer.

  4. 1 to 2 weeks after the lab gets it

    Get your Level

    Your Individual Sweat Profile arrives by email with your Level and plan. Starter Kits then ship your first pouch at that Level.

Athletes on LEVELEN

Tested, then matched

Getting sweat tested by LEVELEN has been critical for me to keep getting faster. Through a recent Sweat Test in Kona, we were able to tweak my fuel plan to best my 2009 time by 40 minutes.

Before finding LEVELEN, I felt like I was shooting in the dark with my nutrition. Since taking the sweat test and using LEVELEN Level 5, I have noticed a dramatic improvement in my overall performance.

Why test

The typical endurance athlete loses about 1,500 mg of sodium an hour

Sodium loss varies a lot from one athlete to the next, so a one-size electrolyte drink can be too little for some and more than others need. The Sweat Test measures your number, and the lab assigns one of three Levels, each with a matching mix.

Median sodium loss across more than 4,000 endurance-athlete sweat tests run by LEVELEN since 2016. Testing is run by the lab of LEVELEN co-founder Dr. Sandra Fowkes Godek, PhD, ATC, using LEVELEN's patented method (US Patent 9,421,226).

I'm buying a Sweat Test. Do I get the subscription offer too?

Yes. Your results arrive 1 to 2 weeks after the lab gets your sample, so the offer waits for you: use code FIRSTPOUCH30 on your first subscription order for 30% off your first pouch, any time through Dec 31.

Single Sport or Endurance?

Most athletes only need Single Sport. Endurance kits include two tests for one athlete: bike and run, or the same sport in two different conditions, like a cool day and a hot day.

What's in a Starter Kit?

The full Sweat Test, your Individual Sweat Profile by email, and your first pouch of LEVELEN mix. The pouch ships after your results, so it matches your Level.

How long do results take?

Usually 1 to 2 weeks after the lab receives your sample. Your profile arrives by email with your Level and plan.

Can I give it as a gift?

Yes. Enter their address at checkout. They test during a normal workout whenever it suits their training.

What's in the mix?

Sodium matched to your Level (900, 1,200 or 1,500 mg per liter), carried by dextrose. It comes in Strawberry-Citrus, Lemon-Lime and Neutral.

Is it right for everyone?

If you have high blood pressure or kidney issues, or take diuretics, check with your doctor before using an electrolyte mix.
