Nutrition Consultancy
Nutrition Consultancy for Endurance Athletes
Smarter Fuel. Faster Racing.
Whether you’re aiming for a strong finish or a Kona slot, your carbohydrate and hydration plan needs to reflect your physiology, race intensity, and environmental demands.

Choose from three levels of support—remote, consultative, or fully tested in-person at our Watford lab.
Dial in your race-day fuelling strategy.
Essential Plan – £125
Remote race-day fuelling strategy using athlete-supplied data
Perfect for those looking for a high-quality, personalised plan without in-person testing.
Includes:
Athlete questionnaire + performance data interpretation
Weight + muscle mass (via BIA) used to estimate muscle glycogen storage
Predicted CHO targets per hour based on pacing and race duration
Hydration strategy based on race type, weather, and sweat history
Plan delivered via email with 7-day Q&A support
Best for: First-time Ironman & 70.3 athletes, marathoners, or endurance cyclists
Advanced Plan – £179
Deeper insight and coaching feedback for data-driven athletes
Ideal for athletes who want more precision without full lab testing.
Includes:
60-minute video consultation with Jon
Muscle mass analysis to estimate glycogen capacity and required carb load (g/day)
CHO usage breakdown by heart rate or power zones
Fully customised race fuelling plan
Post-session Q&A support (7 days)
Optional Add-ons:
- RMR Test (£125)
- VO₂ Max Test (£125)
- FlowBio Sweat Rate & Sodium Testing (£on request)
Best for: Returning athletes, long-course competitors, and club racers seeking to upgrade their fuelling accuracy
Performance Lab Plan – from £325
The gold standard: testing, analysis, and a fuelling plan built on your actual physiology
Built for athletes chasing PBs, age-group podiums, or world championship qualification.
Includes:
Resting Metabolic Rate (RMR) Test – taper-week fuelling and energy needs
VO₂ Max Test (bike or run) – pinpoints CHO vs fat usage by intensity
FlowBio Real-World Sweat Test – captures sodium loss and sweat rate during training
Muscle Mass Analysis via Hume Formula – estimates glycogen storage capacity, sets exact carb load and in-race intake (g/hr)
60-minute consult + pre-race review session
Custom fuelling plan built from your physiology, pacing, and race demands
FlowBio sensors used in lab or sent to you for 7-day real training application. This reflects actual race conditions—not artificial lab sweat responses.
Best for:
- World Championship & Age-Group qualifiers

Pre-race carb loading structure
Recommended fuelling products and intake timing
Delivered via email + 7-day Q&A support
Ideal for:
- First-time Ironman & 70.3 finishers
- Marathoners and sportive riders
- Athletes seeking structured but simple race fuelling
Performance Plan – from £325 (With Testing)
VO₂ Max Test: Determines precise CHO vs fat usage across heart rate/power zones
Resting Metabolic Rate (RMR) Test: Establishes taper-week fuelling needs and recovery energy demands
FlowBio Sweat Testing: Captures real-world sweat rate and sodium loss during training—not in a lab
Muscle Mass Analysis via Hume Formula:
- Uses lean body mass from high-accuracy BIA scales
- Predicts total muscle glycogen storage capacity
- Determines optimal carb load (g/day) and in-race fuelling rate (g/hr)
All data combined into a personalised race-day fuelling strategy, refined by athlete pacing, training history, and climatic factors
Includes a 60-minute consult + pre-race follow-up
Ideal for:
- PB attempts

Review from One of the Many Happy Clients
Jon give me great advice over phone calls and regular follow up messages.
He sent me a full plan for the weeks leading up to my event as well as a plan for on the day. I specifically told him I had issues with cramps and through following his plan I did not have a single cramp on the day and smashed my sub-6 70.3 goal.
