Nutrition made practical.

Fuel the work. Hydrate for the conditions. Recover properly. Arrive at the start line with a plan you have already tested. This page is the JBST nutrition hub — consultations, race fuelling, sweat & sodium testing, tools, articles and evidence-led performance nutrition.

For coached athletes

Nutrition is part of coaching, not an afterthought. Training load, race demands, sweat losses, gut tolerance, body composition goals and everyday life all affect the plan.

Train it. Don’t guess it.Race nutrition works best when it has already been rehearsed in training and adjusted from real feedback.

The Nutrition menu

Start with the problem you actually need to solve. Some athletes need a conversation; some need a race plan; some need measurement.

Consultation • Remote / 1-to-1

Nutrition consultation

A focused review of training, everyday diet, race demands and the practical changes most likely to help.

Everyday fuelling around training
Body composition and energy availability
Recovery, protein and meal timing
Supplements and evidence review

Race day • Fuel + hydration

Race nutrition strategy

Build the plan around duration, intensity, conditions, aid stations, products and what your gut will actually tolerate.

Carbohydrate target and timing
Fluid and sodium plan
Caffeine and evidence-led ergogenics where appropriate
Training sessions used to rehearse the plan

Measure • FLOWBIO AHi

Sweat & sodium testing

Use measured sweat and sodium losses to turn hydration from a generic recommendation into an athlete-specific plan.

FLOWBIO AHi testing during exercise
Sweat rate and sodium-loss interpretation
Training and race hydration targets
Can be paired with CORE heat testing

Coaching • Integrated

Nutrition inside coaching

For coached athletes, nutrition is adjusted alongside the training rather than treated as a one-off spreadsheet.

Fuel the actual training load
Practice long-session and race feeding
Adjust around travel, illness, heat and body-composition goals
Review what worked after key sessions and races

Tools, articles & useful rabbit holes

This is the hub rather than another silo. Where JBST already has a useful tool, article or testing page, Nutrition should point to it.

Fuel

Carbohydrate before, during and after training; long-session fuelling; recovery; gut training and race-morning planning.

Find articles / Q&A

Hydrate

Fluid, sodium, sweat-rate and hot-weather planning. When measurement helps, jump straight into FLOWBIO AHi and CORE testing.

Sweat + heat testing

Perform

Caffeine, sodium bicarbonate, nitrate, creatine and other evidence-led ergogenic strategies — with context, not magic-bullet claims.

JBST tools

Race planners & calculators

JBST tools already bring together pacing, carbohydrate, sodium, fluid and race execution. Keep the calculations with the tools and use this page as the doorway.
