Your peak marathon running performance is only possible with precision sports nutrition—guided by an expert marathon running nutritionist in Sydney. This is where science meets strategy to fuel your body for elite marathon running results.
Are you constantly running out of energy during long runs, struggling to recover between training sessions, or finding it harder to maintain pace, strength, and mental focus across your training plan? Do you feel your legs staying sore, tight, and slow to bounce back? Is fatigue setting in too quickly, long runs feeling harder, or motivation dropping — leaving your body breaking down instead of building endurance? Stuck in a cycle of exhaustion, injury risk, and frustrating plateaus?
As a marathon running nutritionist in Sydney, I work with runners of all levels to break this cycle. With evidence-based endurance nutrition strategies, I help you fuel longer runs, improve stamina, sharpen focus, speed up recovery, maintain muscle strength, and reduce injury risk.
I work with elite and competitive athletes, and I share with you the exact strategies I use with them to unlock peak performance — so you can step onto race day with confidence, consistency, and the energy to perform at your absolute best, mile after mile.
This is not your standard sports nutrition consultation with a sports nutritionist or sports dietitian. This is a detailed, evidence-based sports nutrition consultation designed specifically for marathon runners who are serious about unlocking their peak endurance, improving recovery, and maximising performance through meticulously tailored nutrition strategies.
First 45 Minutes – Clinical Marathon Performance Assessment: In the first 45 minutes, we’ll take a deep clinical dive into your marathon training and performance to uncover what’s holding you back—and why. This begins with a full nutritional analysis, examining your macro- and micronutrient intake and how it’s fuelling your body across different training intensities. We’ll assess whether your current intake supports sustained energy during long runs, rapid recovery after intervals, and optimal performance on race day. If you’re underfuelling, mis-timing your intake, or missing key nutrients, we’ll identify it.
Next, we’ll evaluate your training load, recovery patterns, and endurance metrics to understand how your body is responding to stress. Are you recovering fast enough between sessions? Is fatigue creeping in too early during long runs? Are your muscles staying fuelled and resilient across training blocks? We’ll pinpoint the physiological and nutritional barriers—whether it’s inconsistent energy, sluggish recovery, or delayed adaptation—and map out how they’re affecting your performance.
This session isn’t just diagnostic—it’s strategic. Together, we’ll set clear short- and long-term goals tailored to your physiology, training history, and race ambitions. Whether you’re aiming to complete long runs with more energy, improve training consistency, or bounce back faster between sessions, you’ll leave with a clear understanding of what’s going wrong and a plan to fix it. You’ll gain clarity, confidence, and a renewed sense of control over your training.
Final 15 Minutes – Your Personalised Marathon Running Peak Performance Sports Nutrition Plan: In the final 15 minutes, I’ll deliver a precision-crafted, evidence-based blueprint designed to elevate your marathon performance—and sustain it. This plan integrates optimal nutrition, personalised training strategies, and lifestyle adjustments that reflect your unique physiology, goals, and pain points. It’s not generic—it’s built around you.
We’ll address the most common endurance challenges head-on. You’ll learn how to fuel effectively during long runs to avoid energy crashes and gastrointestinal discomfort. We’ll cover how to support muscle recovery between sessions, reduce inflammation, and maintain consistent energy across training blocks. If you’ve struggled with hitting the wall, inconsistent pacing, or post-run fatigue, this plan will show you how to overcome it.
You’ll walk away with a clear, actionable roadmap that empowers you to train smarter, recover faster, and race stronger. This isn’t just about peak performance—it’s about building resilience, reducing injury risk, and sustaining progress across training cycles and race seasons. You’ll leave the consultation feeling energised, motivated, and equipped with the tools to reach your marathon goals with confidence and consistency.

| Poor Marathon Nutrition | Optimal Marathon Nutrition With Myself |
|---|---|
| Frequent energy crashes during long runs or high-mileage training, leaving you fatigued and struggling to maintain pace. | I design personalised fueling strategies that provide sustained energy for every kilometre, incorporating carbohydrate periodisation, balanced macronutrients, and pre-, mid-, and post-run nutrition to keep you running strong. |
| Slow recovery, persistent muscle soreness, and delayed adaptation to training loads. | I optimise your recovery with timed protein intake, anti-inflammatory foods, and targeted micronutrients to repair muscles efficiently and accelerate adaptation to high training volumes. |
| Inconsistent pace and performance plateaus due to poor fuel availability and inadequate glycogen stores. | I help you maintain optimal glycogen levels and train your gut for race-day nutrition tolerance, so you can improve running economy, push past plateaus, and sustain your ideal pace. |
| High risk of injuries, joint discomfort, and connective tissue strain from chronic under-fuelling and poor recovery nutrition. | I support musculoskeletal health with anti-inflammatory foods, collagen-rich nutrition, and optimal protein and micronutrient intake, reducing injury risk and enhancing joint and connective tissue resilience. |
| Mental fatigue, lack of focus, and decreased motivation during training and race day. | I stabilise blood sugar, provide key micronutrients, and implement hydration strategies that enhance mental clarity, focus, and motivation so you stay sharp in every session and on race day. |
| Dehydration, electrolyte imbalance, and risk of cramps or hyponatraemia during long runs or hot-weather races. | I create personalised hydration and electrolyte protocols to maintain fluid balance, prevent cramps, and optimise thermoregulation in any training or racing condition. |
| Fluctuating body weight, inefficient fuel utilisation, and suboptimal body composition for running performance. | I guide you to achieve an ideal body composition for endurance running, enhancing aerobic efficiency, energy utilisation, and overall performance through targeted nutrition strategies. |
| Inconsistent performance across different training blocks and races due to poor adaptation to volume and intensity. | I structure your nutrition to match training cycles, ensuring consistent performance, efficient adaptation to mileage and intensity, and peak readiness for every race. |
| Cravings, energy dips, and poor hunger control disrupting training and recovery. | I design nutrient-dense meals and snacks with precise macronutrient timing to stabilise appetite, prevent energy dips, and support smooth recovery between sessions. |
| Micronutrient deficiencies impairing immune function, recovery, and overall performance. | I ensure your nutrition includes all essential vitamins, minerals, and antioxidants to strengthen immunity, optimise energy metabolism, reduce inflammation, and enhance long-term training adaptations. |
| Poor sleep and delayed recovery cycles further contributing to fatigue and reduced training effectiveness. | I implement nutrition strategies that support circadian rhythm, hormone balance, and muscle repair, helping you sleep better and recover faster. |
| Mental burnout and lack of resilience in high-volume training weeks. | I tailor your nutrition, hydration, and recovery protocols to maintain mental resilience, motivation, and focus throughout intense training blocks. |
| Slow adaptation to progressive training load and inconsistent endurance improvements. | I accelerate adaptation to mileage and intensity with precise fuel strategies, recovery optimisation, and gut training for efficient nutrient absorption and improved endurance. |
| Overall risk of overtraining, illness, and injury due to inadequate nutrition and recovery planning. | I create balanced, periodised nutrition and recovery plans that prevent overtraining, maintain immune function, and support long-term endurance performance safely and effectively. |
