Mistakes to avoid in your Marathon

5 February 2026

A marathon can be consider to be the ultimate test of preparation, patience, and mental grit. Months of training lead to one day. While things won’t always go perfectly, avoiding common mistakes can help you run your best race and more importantly… enjoy it!

HERE ARE SOME OF THE BIGGEST MARATHON PITFALLS AND HOW TO STEER CLEAR OF THEM:

  1. Starting Too Fast
    The adrenaline at the start line is real, and it’s easy to get swept up by the crowd. But going out too fast in the first 5–10 km will almost always lead to hitting the wall later. Start at (or just slower than) your planned goal pace and save your energy for the second half.
  2. Ignoring Fuel and Hydration
    If you wait until you’re thirsty, tired, or hungry to eat or drink, it’s too late! Start fuelling early (around 30–40 minutes in) and take small, regular sips of water or electrolyte drink throughout the race.
  3. Trying Something New on Race Day
    That “magic” gel from the expo? Those brand-new shoes? Leave them for another time. Race day is for gear and fuel you’ve tested during training. Avoid the temptation and stick to what you know!
  4. Overtraining or Undertraining
    Cramming too much mileage at the last minute can lead to injury. On the flip side, not doing enough long runs can leave you unprepared for the distance. A balanced plan with progressive mileage is key. Be honest with yourself where you are sitting on this see-saw during your training.
  5. Neglecting the Taper
    Some runners panic during the taper, feeling like they’re losing fitness. But the taper (reducing mileage and intensity for the 2–3 weeks before the race) is what allows your body to absorb all the hard training and arrive to the start line fresh.
  6. Forgetting the Mental Game
    Marathons aren’t just physical, they are mental. Having mantras, remembering your why, breaking the race into smaller sections, and focusing on the present moment can help when things get tough.

Mistakes in a marathon can be costly, but many are avoidable with preparation and self-control. Respect the distance, trust your training, and remember: the smartest race is usually the fastest one in the end.
