Sodium is the key electrolyte you lose in your sweat and it’s crucial to your hydration status. The thing is, everyone loses a different amount of sodium in their sweat, from as little as 200mg of sodium per litre, to 
as much as 2,000mg/L. This is largely genetically determined and our 
at-rest Sweat Test can tell you how much you lose so you can dial in 
your hydration strategy.

What it involves

• Sittingcomfortably for ~30-45 minutes whilst our Sweat Test kit stimulates a small patch of your forearm to sweat maximally and we collect a sample
• No needles, no exercise

What you learn

• Understand your sweat sodium concentration (in milligrams per litre of sweat), so you can tailor the strength of your drinks
• A detailed report and consultation with a hydration specialist
• A fuel & hydration plan for your next race (and access to the planning software for future races)
