What this guide is for

Use this guide to remove guesswork in race week: keep routines stable, top up carbs at the right time, and arrive calm and fuelled.

Key takeaways

  • Keep foods familiar — race week isn’t the time for experiments.
  • Carb top-up in the final 24–36 hours (lower fibre + lower fat).
  • Plan breakfast timing (2–3 hours pre-start).
  • Half marathon fueling needs a simple plan; 10K usually doesn’t (if you ate).

·         Hydration is steady, no chugging.

5–7 days out

  • Maintain regular meals, focusing on carbs during key sessions
  • Avoid diet changes
  • Practise planned gels/drinks one last time
  • Prioritise sleep and hydration

24–36 hours out (carb top-up)

Aim: 8–10 g/kg carbs/day (lower fibre + lower fat)
Best choices: rice, pasta, potatoes, bread, bagels, cereals, fruit

  • Add salt to meals (helps hydration)
  • Keep foods familiar

Night before

  • Prepare kit + gels
  • Plan breakfast + timing
  • Set a simple hydration plan

Race morning (2–3 hours before)

Aim: 1–3 g/kg carbs (low fibre, low fat)
Examples: toast + honey | oats + banana | cereal + milk | toast + jam

  • Drink steadily (no chugging)

During the race (choose your event)

10K

  • Usually no fueling needed if you ate breakfast
  • Optional: gel 10–15 min before if practised

Half marathon

  • Target 30–60 g carbs/hour
  • Simple plan: gel 10 min pre-start + 1 gel every 30–35 min
  • Water with gels; sports drink if available

After

  • Carbs + protein within 60 mins
  • Fluids + electrolytes as needed
