half marathon as goal

A half marathon (21.1 km) is a popular challenge for many runners who want to progress. It is ideal for those who have already mastered shorter distances and want to take on a more challenging but doable course. The training period is usually between 10 and 16 weeks , depending on the starting level.

Important factors for half marathon preparation:

  • Regular training (3-4 runs per week) : Slow increase in the number of kilometers
  • Slow, long runs : To improve endurance
  • Interval training : To increase speed and performance
  • Nutrition & Hydration : A balanced diet with carbohydrates, proteins and fats and adequate fluid intake are crucial
  • Regeneration : Plan enough sleep, stretching exercises and rest days. Pay close attention to your body's signals!

Example: Lisa wants to run her first half marathon. She starts with a 12-week plan and increases her long runs by 1-2 km per week. She also takes 2-3 rest days per week so as not to overstress her body.

Marathon as a goal

A marathon (42.195 km) is an extremely demanding challenge that requires months of targeted preparation. The training effort is considerably higher than for a half marathon, as the body must be prepared not only for long distances, but also for the high level of exertion. The training period is usually between 16 and 24 weeks.

Important factors for marathon preparation:

  • Consistent training (4-5 runs per week) : combination of long runs, intervals and tempo runs
  • Long runs of 30+ km : To get the body used to the continuous strain
  • Mental preparation : A marathon requires not only physical but also mental strength
  • Detailed race strategy : When do I eat and drink? How do I keep my pace constant?
  • Injury prevention : Strengthening the muscles through additional strength training and stretching programs
  • Regeneration : Plan enough sleep, stretching exercises and rest days. Pay close attention to your body's signals!


Example: Max has decided to run his first marathon. His goal: to finish in under four hours. To achieve this, he is planning a structured 20-week training program with specific units.
