Walk into any supplement store and the pre-workout shelf is overwhelming — brightly coloured tubs promising explosive energy, insane pumps, and next-level performance. Most of these products are designed for gym-goers chasing a maximal lift, not endurance runners whose needs are very different.
This guide cuts through the noise. It covers the evidence-based supplements that genuinely help runners, explains the science behind each, and recommends specific products available in Australia that are worth your money in 2026.
What Runners Actually Need Pre-Workout
Runners need different things from a pre-workout supplement compared to strength athletes. The priorities are:
Energy without jitteriness: Smooth, sustained energy that doesn't spike and crash mid-run. The stimulant profiles in many commercial pre-workouts are too intense and too short-lived for running.
Endurance performance: Compounds that delay fatigue, improve aerobic efficiency, and support sustained effort over time.
Hydration support: Many runs are long enough that starting well-hydrated with electrolytes is performance-relevant. Pre-workout electrolytes or hydration can support this.
No GI distress: Anything that causes stomach issues mid-run is worse than nothing. Many pre-workout ingredients (artificial sweeteners in large quantities, citrulline at high doses) can trigger GI upset during running's constant jarring motion.
The Evidence-Based Ingredients
Caffeine
Caffeine is the most researched ergogenic aid in sports nutrition, and the evidence for its performance benefits is overwhelming. Relevant to runners:
- Aerobic endurance: Caffeine improves time-to-exhaustion at submaximal efforts by 20–50% in well-controlled studies
- Time trial performance: 3–7% improvement in running time trials of 5–30 minutes duration
- Perceived exertion reduction: The same pace feels easier with caffeine — a significant benefit in racing
- Optimal dose: 3–6mg per kg of body weight, 45–60 minutes before exercise. For a 70kg runner, this is 210–420mg
- Habitual use reduces effects: Caffeine tolerance develops rapidly. Consider cycling off for 3–5 days before important races to restore responsiveness
Practical note: Not all caffeine sources behave the same. Anhydrous caffeine (in most supplements) hits fast and hard. Caffeine from coffee is slightly slower-onset and paired with other compounds that modulate its effects. Slow-release caffeine formulations extend the performance window.
Beta-Alanine
Beta-alanine is a precursor to carnosine, a dipeptide that buffers hydrogen ions in muscle tissue during high-intensity exercise. As acid accumulates during intense effort, carnosine neutralises it, delaying the burning sensation and fatigue associated with the lactate threshold.
- Most effective for: High-intensity efforts lasting 1–4 minutes (400m–1,500m running, threshold intervals)
- Less relevant for: Easy to moderate aerobic running where acid buffering isn't a limiting factor
- Loading requirement: Beta-alanine must be supplemented for 4+ weeks (3.2–6.4g daily) to significantly increase muscle carnosine. Pre-workout doses alone are insufficient
- Tingling (paresthesia): Most users experience skin tingling at doses above 800mg. This is harmless but can be distracting. Split doses reduce this
Beetroot / Nitrate
Dietary nitrate from beetroot (or beetroot juice concentrate) is converted to nitric oxide in the body, which dilates blood vessels and reduces the oxygen cost of exercise.
- Mechanism: Improved oxygen efficiency means a given effort requires less oxygen — effectively raising the ceiling on aerobic performance
- Effective dose: 400–600mg of inorganic nitrate, equivalent to ~500ml of beetroot juice or 70ml of concentrated shots (like James White Beet It)
- Timing: 2–3 hours before exercise for peak plasma nitrate levels
- Most effective for: Recreational runners (moderately trained). Elite runners show smaller responses, possibly due to already optimised nitrate metabolism
- Evidence: Consistent 1–3% performance improvements in time trials, particularly at moderate intensities
Sodium Bicarbonate (Bicarb)
Sodium bicarbonate (baking soda) is one of the oldest performance supplements used by athletes. It acts as a blood pH buffer, delaying acidosis during high-intensity exercise.
- Dose: 0.3g/kg body weight, 1–2 hours before exercise (for a 70kg runner: 21g)
- GI warning: Large doses commonly cause significant GI distress — nausea, cramping, and worse. This side effect is common enough that bicarb is a significant gamble in racing. Testing in training is essential
- Most relevant for: Middle-distance runners (800m–5K), track athletes, threshold intervals
- Low-dose protocols: More recent research suggests 0.2g/kg with smaller increments reduces GI risk while maintaining some benefit
Creatine Monohydrate (Long-Term)
Creatine is primarily known as a strength training supplement, but it's increasingly relevant for endurance runners:
- Sprint and interval benefit: Creatine improves repeated sprint capacity and high-intensity interval performance
- Recovery: Some evidence for reduced muscle damage and faster recovery between hard training days
- Brain function: Emerging research suggests creatine supplementation improves cognitive function under fatigue — relevant for very long runs and races
- Dose: 3–5g daily (maintenance phase). No loading phase required
- Weight gain: Creatine causes water retention (1–2kg typically). For road runners concerned about weight, this is worth considering
Electrolytes
Pre-run electrolyte loading is particularly relevant in warm conditions, before long runs, or when running early in the morning (after overnight sodium loss through sweat from sleeping):
- Sodium: The primary electrolyte lost through sweat. Pre-hydration with sodium (500–1,000mg) improves fluid retention
- Potassium, magnesium: Support muscle function and nerve transmission
- Practical approach: An electrolyte tablet or sachet in water 60–90 minutes before a long run

What to Avoid
High-stimulant commercial pre-workouts: Products designed for gym workouts often contain 300–400mg caffeine, high-dose synephrine, and other stimulants that cause jitteriness, elevated heart rate, and GI distress during running. These are not appropriate for endurance running.
Artificial sweeteners in large quantities: Many pre-workouts use sucralose and acesulfame-K heavily. These can cause GI distress during running's repetitive impact. If your stomach is sensitive, look for products sweetened with stevia or nothing at all.
Novel/untested ingredients: In Australian competitive sport, WADA compliance matters. Stick to well-researched ingredients with established safety profiles, and check labels against the WADA prohibited list if you compete.
Anything within 4 hours of bed: Pre-workout caffeine taken late afternoon will destroy sleep quality, which has far greater impact on performance and recovery than any supplement.
The Bottom Line
For most runners, a pre-workout protocol of caffeine (at the right dose and timing), beetroot nitrate for key sessions, and electrolyte loading for long runs in warm conditions provides the most evidence-backed performance enhancement available.
Avoid being seduced by heavily marketed commercial pre-workouts — the ingredients that have real evidence behind them are simple and inexpensive. Focus on the basics, test everything in training before race day, and remember that no supplement compensates for inadequate training, sleep, or nutrition.
Always check supplement ingredients against WADA prohibited list if competing under anti-doping regulations. Consult a sports dietitian for personalised supplementation advice.
