Sweat Testing, Hydration & Fuelling Consultation
Evidence-based hydration and fuelling built around your sweat physiology, tolerances and race goals.
Tim Reed and the RPG team combine decade-long applied experience with gold-standard sweat analysis to deliver practical, personalised hydration and fuelling strategies. Because electrolyte losses are largely genetic and highly individual, every plan is based on measured sweat chemistry, sweat volume across conditions and what you actually tolerate.
What we do:
Measure sweat sodium concentration with industry-leading, on-site instrumentation.
Estimate sweat rate across conditions so we can calculate total sodium and fluid loss (mg/hr & L/hr).
Detailed nutrition & tolerance interview — foods, gels and electrolytes you tolerate.
Produce a practical, personalised fuelling & hydration plan for training and racing (by duration, temperature and event).
Who it’s for:
All endurance athletes who want a personalised hydration/fuelling plan rather than one-size-fits-all advice.
Session outline (35–45 minutes)
Pre-test intake & instructions.
Baseline measures & sweat collection.
On-site, painless sodium analysis (no blood test).
Immediate debrief + written report delivered within 5 working days.
Follow-up: 20-minute refinement call included if required.
Metrics & deliverables:
Sweat sodium (mg·L⁻¹), sweat rate (L·hr⁻¹), estimated sodium loss (mg·hr⁻¹).
Fluid replacement targets (mL·hr⁻¹).
Carbohydrate targets (g·hr⁻¹), product/recipe suggestions and a race-day plan.
Risk flags and mitigation strategies.
