Training tips

  • 1.Progress your long run to maximum 32-35k (never 42k in training)
  • 2.Train your fueling strategy - CRITICAL for marathons
  • 3.Test complete setup (shoes, clothes, gels) on long runs
  • 4.Listen to your body - an extra rest day beats injury

Frequently Asked Questions

How long does it take to run a marathon as a beginner?

A beginner marathoner typically finishes in 4h to 5h30. Average pace is 5:45 to 7:45 min/km depending on fitness. What matters is finishing and enjoying the experience. A medal waits at the finish!

Do I really need to run 40+ km during training before the marathon?

No! You never need to run the full 42k. Your longest run should be 32-35k maximum. This is enough to adapt your body to the distance. Building mental confidence matters more than physical distance.

How do I manage nutrition over 42k?

This is THE key to marathons! Consume 30-60g carbs per hour (gels, drinks, energy bars). Start fueling after 45 min. Hydrate regularly but not excessively (500ml/hour). Test your system absolutely on long runs - never test on race day!
