DIAL YOUR HYDRATION

Understand your sweat rate and sodium losses so you can fuel properly, stay hydrated, and perform better in training and racing.

RHSN has a network of certified sweat testing partners around the country.

Inability to fuel consistently

Can't tolerate gels or high-carb fuels

Early fatigue onset that doesn't improve with fuelling

SIGNS YOUR NUTRITION ISN'T DIALLED

"DIALLING YOUR HYDRATION IS ONE OF THE BIGGEST PERFORMANCE LEVERS YOU CAN PULL. TRAINING AND RACING IN A HYDRATED STATE ALLOWS YOU TO PERFORM FOR LONGER AND KEEPS FUELLING ON TRACK."

MOST FUELLING ISSUES ARE HYDRATION ISSUES.

When we sweat, we lose both fluid and sodium.

If both aren't replaced properly, things start to fall apart:

energy drops
gut issues kick in
heart rate drifts up
performance declines

MOST ATHLETES DON'T KNOW OR REALISE HOW MUCH THEY ACTUALLY LOSE.

The amount of sodium in each person's sweat is quite individual, and can range from about 200-2000mg/L. When sodium replacement isn't matched with your individual sodium loss, dehydration takes hold. In extreme cases, not replacing enough sodium can lead to hyponatraemia, which is extremely dangerous.

A NUMBER ALONE IS NOT A STRATEGY.

A sweat test gives you your sodium concentration, but your actual needs depend on:

how much you sweat (sweat rate)
how hard you’re working
the conditions you’re in
how long you’re exercising

Two athletes with the same sweat sodium can need very different hydration strategies. That’s why the goal isn’t just testing - It’s building a plan you can actually use.

SWEAT TESTING TAKES LESS THAN AN HOUR AND THE RESULTS ARE INSTANT.

Sweat is collected from multiple sites during 30-60 minutes of exercise to determine your sodium losses, and this is combined with sweat rate to build your hydration plan.

You’ll leave knowing:

how much to drink
how much sodium to take in
how to adjust for different sessions and races
