Fuelling With Purpose — 27 May 2025


💡 Fuel For Thought

Why your race nutrition plan should never be decided the week before

When it comes to race prep, most athletes wouldn’t dream of leaving their training to the last minute.

And yet, many wait until race week, or even race day, to start thinking seriously about fuelling.

But here’s the truth: your race nutrition strategy should be prepared just like your legs.

Trying a new gel, upping your carb intake, or suddenly “carb loading” without practice can do more harm than good. Race-day nutrition isn’t just about what you eat that morning, it’s about what your gut, brain, and body are prepared to handle.

  • Your brain needs to trust the plan.
  • Your body needs to tolerate the fuel.
  • Your gut needs training to absorb nutrition efficiently under stress.

And when it comes to ultras, it’s not just the biology, it’s also the logistics.

You need to consider:

  • The course. What’s available at aid stations (and what isn’t).
  • Your crew. What they can carry and when you’ll see them.
  • The conditions. Will it be hot, cold, hilly, humid? That changes everything.

These elements don’t fall into place the night before. The fuel that works on paper only works in practice when you’ve tested it, during long runs, in different conditions, and ideally with your crew.

If you’ve got a big race coming up, the best time to start building your fuelling strategy is now.

Because the best race plans aren’t just about crossing the finish line. They’re about performing at your best, with no gut issues, no surprises, and no guesswork on the day.


🚀 Endurance Highlights

1️⃣ Want to recover faster? Eat sooner

What and when you eat after your training session can significantly impact your recovery and long-term adaptation. This recent systematic review and meta-analysis looked at how the timing of post-exercise nutrition, particularly protein and carbohydrates, affects fatigue, muscle repair, and glycogen replenishment.

Immediate intake (within 30 minutes) after training appears to offer the greatest benefit for muscle recovery and energy restoration, especially after high-intensity or prolonged exercise. While some studies showed that delayed intake (1–2 hours later) can still support recovery, the most consistent improvements were

Whether it’s a shake (see suggestion below), a proper meal, or a combo of both, making sure you refuel promptly can help your body bounce back stronger.


2️⃣ A small tweak to your nighttime routine that might support recovery

Speaking of recovery, pre-sleep protein intake has been linked to improved muscle repair and training adaptations, too.

This study explored whether combining casein protein with probiotics before bed could offer added benefits for performance in soccer players.

Over four weeks, athletes consumed 20g of casein protein about 45 minutes before sleep, with or without a multi-strain probiotic taken at dinner.

All groups trained as usual, but those who consumed both casein and probiotics saw modest but measurable improvements in lower-body strength, power, and anaerobic capacity compared to the placebo group. The combination outperformed both casein and probiotics individually, suggesting a synergistic effect, likely due to enhanced nutrient absorption, improved gut health, and more efficient muscle repair during sleep.

While this study focused on soccer players, the findings are promising for any athlete training hard, especially in sports that require repeated high-intensity efforts or explosive strength.

💡 Fuel For Thought The nutrition story behind Phil Gore's backyard ultra world record I wasn’t planning to be at the Dead Cow Gully Masters Backyard Ultra this year until I received a message late Friday night from Phil Gore and a call from his wife, Gemma, letting me know she’d broken her ankle and asking if I could take her place as crew. Just hours later, I was on a plane to Queensland, about to witness one of the most incredible performances in ultra-endurance history. Phil went on to...

💡 Fuel For Thought Why hunger isn't your best guide during training Outside of training, your hunger cues are usually reliable. If you’re feeling hungry during your regular day-to-day activities, it’s a good sign your body needs food, and responding to that is smart. But once you step into a long run, ride, or race… things change. Exercise suppresses appetite, even when your body is burning through energy rapidly. So if you wait to feel hungry before eating during training, you’re already...

💡 Fuel For Thought Mastering the invisible training One of the most memorable concepts I learned during my university years came from a sports nutrition lecturer who often spoke about the importance of “invisible training.” She used this term to describe everything that supports performance but isn’t captured in your training log: nutrition, hydration, sleep, and mindset. The things that happen off the track, away from the gym, and outside of the long runs. Nutrition, of course, is one of the...
