Common mistakes

  • Running the first 5km in 23 minutes — it feels fine, it isn't
  • Skipping water stations to avoid losing time
  • Ignoring the slight incline on your course — flat pace targets don't account for hills

Key race day tips

  • First 10km target: 53:00 — not 51:00
  • One gel at 40–45 minutes makes the final 5km significantly better
  • km 15–18 is where most people slow — this is your moment to hold pace
