Australian IRONMAN champion Matt Poole has logged thousands of kilometres of open-water swimming, cycling, and running — and he'll tell you straight: what you do after training matters just as much as what you do during it. Here's a breakdown of the recovery principles elite endurance athletes live by, and how smart supplementation from our recovery range can help support your own training.
- Elite endurance athletes treat recovery as a structured training phase, not an afterthought.
- Hydration and electrolyte replacement are the first priority after any long session.
- EAAs and BCAAs may help support muscle protein synthesis and reduce training-related muscle soreness.
- The 30-to-60-minute post-training window is widely considered the most important time for nutrition.
- Consistency over weeks and months — not a single "recovery hack" — drives long-term endurance adaptation.
- Quality sleep and active recovery days are non-negotiable; supplements are a supporting tool, not a replacement.
Who Is Matt Poole?
Matt Poole is one of Australia's most accomplished IRONMAN triathletes — a multiple podium finisher who has competed at the highest levels of long-course triathlon. An IRONMAN event covers a 3.8 km swim, 180 km bike, and a full 42.2 km marathon run, all in a single day. Athletes of Matt's calibre don't just train hard; they've built precision recovery systems that allow them to back up day after day, week after week.
What Matt's career demonstrates is a principle that applies equally to competitive age-groupers and gym members doing their first fun run: your body improves during rest, not during the workout itself. Training is the stimulus; recovery is where adaptation happens.
Principle 1 — Rehydrate Before You Do Anything Else
After a long endurance session, your first job is fluid and electrolyte replacement. Sweat doesn't just contain water — it carries sodium, potassium, magnesium, and chloride. Replacing water alone without replacing electrolytes can leave you feeling flat and may impair muscle function in subsequent sessions.
Research suggests that replacing lost fluids with an electrolyte-rich drink in the first 30–60 minutes post-training supports faster restoration of fluid balance compared to water alone. For athletes training in Victoria's summer heat or backing up training days, this is especially relevant.
Emrald Labs Electrolyte+
A well-rounded electrolyte formula that may help support fluid balance and hydration as part of a balanced diet and training program. Great for post-session replenishment.

Principle 2 — Replenish Carbohydrates and Top Up Protein
Endurance training depletes muscle glycogen — the stored carbohydrate your muscles use as primary fuel. Replenishing glycogen in the 30–60 minutes after training is widely supported in sports nutrition literature, particularly when athletes are training again within 24 hours.
Alongside carbohydrates, protein plays a critical role in repairing muscle tissue that is broken down during both endurance and resistance training. The combination of carbohydrates and protein post-workout may support faster glycogen resynthesis and muscle protein synthesis compared to either nutrient alone.
For endurance athletes, real food sources — a banana with Greek yoghurt, rice with chicken, or a quality recovery shake — form the backbone of post-training nutrition. Supplements fill gaps; they don't replace meals.
Principle 3 — EAAs and BCAAs for Muscle Recovery Support
Essential Amino Acids (EAAs) include all nine amino acids the human body cannot synthesise on its own — including the three Branched-Chain Amino Acids (BCAAs: leucine, isoleucine, and valine). Leucine in particular is understood to act as a key signal for muscle protein synthesis.
Research suggests that EAA supplementation may help support muscle recovery and reduce exercise-induced muscle protein breakdown as part of a training program and adequate overall protein intake. For athletes who train fasted, travel frequently, or struggle to hit protein targets through whole food alone, an EAA supplement can be a convenient and practical tool.
"The difference between good athletes and great athletes is often what they do in the 23 hours they're not training."
EHP Labs Beyond BCAA+EAA
Combines BCAAs and EAAs in one formula to help support muscle recovery as part of a balanced training program. Available in a range of flavours for 60 serves per tub.
Shop Now →If you're already hitting adequate daily protein through whole food, BCAAs alone may add limited benefit. If you're in a calorie deficit, training fasted, or struggling with recovery between sessions, a full EAA product is the stronger choice because it supplies all the amino acids required for the protein synthesis process — not just three.
Principle 4 — Advanced Hydration for Multi-Day Training Blocks
When training volume is high — multi-day blocks, race-week tapering with residual fatigue, or back-to-back long sessions — basic hydration strategies sometimes aren't enough. Athletes in this situation often benefit from more comprehensive hydration formulas that combine electrolytes with osmolyte compounds to support cellular fluid retention.
Emrald Labs Hydration Pro
A more advanced hydration formula designed to support fluid balance during heavy training blocks as part of a balanced diet and training program. Available in Watermelon 350g.

For multi-day race preparation or high-volume endurance blocks, Hydration Pro provides a more comprehensive option worth considering.
Principle 5 — Sleep Is the Non-Negotiable
No supplement stack replaces sleep. Growth hormone — critical for tissue repair and adaptation — is primarily released during deep sleep stages. Elite athletes in sports science settings regularly prioritise 8–10 hours of sleep, and many describe sleep quality as their single most impactful recovery tool.
Practically, this means:
- Consistent sleep and wake times, even on rest days
- Minimising blue-light exposure in the 60 minutes before bed
- Keeping the bedroom cool and dark
- Avoiding high-stimulant pre-workouts late in the day (keep pre-workout sessions to morning or early afternoon where possible — see our pre-workout guide for timing advice)
Building Your Own Recovery Stack
You don't need to replicate the full protocol of a professional IRONMAN athlete. What you can do is apply the same principles at your training level:
- Immediately post-session: Electrolytes and fluid — Emrald Labs Electrolyte+ is a practical first choice.
- Within 30–60 minutes: Carbohydrates and protein from whole food, or a recovery shake if a meal isn't practical.
- During session or intra-workout: EHP Labs Beyond BCAA+EAA may help support muscle recovery, particularly during fasted training or sessions exceeding 60–90 minutes.
- Heavy training blocks: Consider upgrading to Emrald Labs Hydration Pro for more comprehensive hydration support.
- Every night: Prioritise sleep. Non-negotiable.

Frequently Asked Questions
What do elite endurance athletes prioritise for recovery?
Elite athletes like IRONMAN competitors typically focus on four pillars: fluid and electrolyte replacement immediately post-session, carbohydrate and protein intake within 30–60 minutes, amino acid support (EAAs/BCAAs) to support muscle repair, and quality sleep. Supplements play a supporting role — the foundation is always nutrition, hydration, and rest.
What is the difference between BCAAs and EAAs?
BCAAs (Branched-Chain Amino Acids) are three specific amino acids — leucine, isoleucine, and valine — that play a key role in muscle signalling and energy during exercise. EAAs (Essential Amino Acids) include all nine amino acids the body cannot produce on its own, including the three BCAAs. A full EAA product provides the complete set of building blocks required for muscle protein synthesis, which makes it the stronger choice when overall protein intake is low or training is particularly demanding.
Do I need electrolytes after every workout?
For short, low-intensity sessions (under 45–60 minutes) in a cool environment, water is generally sufficient. For longer or more intense training, sessions in hot or humid conditions, or back-to-back training days, electrolyte replacement becomes more important. An electrolyte supplement is a convenient and practical way to replace sodium, potassium, and other minerals lost through sweat.
When should I take EAAs — before, during, or after training?
EAAs are commonly used intra-workout (during the session) or post-workout. Intra-workout use may be particularly beneficial for fasted training or sessions exceeding 60–90 minutes. Post-workout use alongside a meal or protein source can also help support overall daily amino acid intake. EHP Labs Beyond BCAA+EAA works well in either context — mix it during your session or drink it in the recovery window.
How much protein do endurance athletes need compared to gym-goers?
Endurance athletes often need more protein than is commonly assumed. Current sports nutrition guidelines suggest endurance athletes may benefit from 1.4–1.7 g of protein per kilogram of body weight per day, which is not significantly lower than recommendations for strength athletes (1.6–2.2 g/kg). High training volumes increase muscle protein turnover, making adequate protein intake important for both performance and recovery. Individual needs vary — consult a qualified sports dietitian for personalised guidance.
What is the best recovery supplement for someone just starting out?
For beginners, the priority is getting the basics right: whole-food protein after training (eggs, Greek yoghurt, chicken, legumes) and staying well hydrated. If you want to start with one supplement, an electrolyte product like Emrald Labs Electrolyte+ is a practical, low-cost entry point that supports hydration without overcomplicating your routine.
