“There’s no such thing as a good or bad food” | The Nutrition Advice All Runners Need to Hear

If you’re underfuelled, you will underperform.

Most runners are unintentionally holding back their PBs because of "carb fear"-this week, we’re fixing that.

In this episode of The Runna Podcast, sports nutritionist Sian Seccombe explains why underfuelling is one of the most common mistakes runners make. From ‘hitting the wall’ to the serious risks of RED-S, Sian breaks down sports nutrition for runners in a way you can understand and apply.

Whether you're training for a marathon or just started your running journey, this is your ultimate guide to how to fuel for a marathon and beyond.

In this episode, Sian explains:

🍝 Why carbs aren’t the enemy (and why you need more of them)

⏱️ What to eat before a run, during, and after your sessions

⚖️ Why weight loss and marathon training often don’t mix

⚠️ Signs you’re underfuelling (even if you think you’re not)

🧠 What RED-S is-and why it’s frequently missed

Remember, the goal isn’t to eat less 👉 it’s to fuel enough to perform at your best.
