Training for a half marathon typically takes between 12 to 16 weeks for most beginners, depending on your current fitness level and running experience.

• A common beginner training plan spans 12 weeks , gradually increasing running distance and intensity. The first 4 weeks focus on building endurance by running shorter distances 2-3 times a week, then progressively increasing the long run distance each week. Weeks 5-8 introduce speed work like tempo runs and intervals, while weeks 9-12 focus on peak distance runs followed by tapering to allow recovery before race day

• Some plans extend to 16 weeks to allow more gradual build-up of stamina and endurance, especially for those with less running experience. This longer plan is divided into phases: preparation, building, peaking, and tapering, to ensure readiness and reduce injury risk

• For more experienced runners or those who can already run 5K comfortably, training can be shorter, around 8 to 12 weeks , focusing on increasing mileage and speed work

• Weekly commitment usually involves running 3 to 4 times per week, with long runs progressively increasing to about 10-21 km, complemented by rest or cross-training days. Total weekly running mileage typically builds from about 10-15 miles up to 25-30 miles at peak training

In summary, most beginners should plan for about 12 to 16 weeks of training with consistent running, gradually increasing distance and intensity, to safely and effectively prepare for a half marathon. More experienced runners may need less time, around 8 to 12 weeks
