Training for a half marathon typically takes between 8 to 20 weeks, depending on your current fitness level and running experience.
- If you can already run a 5K, you can prepare for a half marathon in about 8 weeks, but the ideal training plan lasts 3 to 4 months (12 to 16 weeks) to allow for a buffer in case of illness, injury, or life interruptions
- Beginners who cannot yet run 3 miles continuously should first build up to that distance before starting a half marathon plan
- Most beginner plans recommend running 3 to 4 times per week, gradually increasing weekly mileage from around 10-15 miles up to 25-30 miles at peak training
- A common beginner training duration is 12 to 16 weeks, with some plans extending to 20 weeks for a more gradual build-up
- Advanced runners with specific time goals may train more intensely, running 5 to 6 days per week and including speed and tempo workouts
In summary, if you are a beginner, plan for about 12 to 16 weeks of training, starting with shorter runs and gradually increasing distance and intensity. If you are already running regularly, 8 to 10 weeks may suffice. The key is consistent mileage buildup and including a weekly long run that approaches 10-11 miles before race day
