This 12-week training plan will get you to the start line strong and ready. The mileage is totally doable because no week goes over 25 miles. There is speedwork to break up the monotony of easy miles but nothing that will stress your body out too much.

Finally, your longest long run is 11 miles. First-timers might be wondering: will I be able to complete the last two miles? The answer is YES, don't stress—those last two miles will come from the work you put into all the training days.

The JOGGO Running App is personalized training and nutrition to help you reach your goals:

Glossary Of Terms

  • Easy runs: This is the pace where you can still speak in full sentences.
  • Strides: Brief spurts of quicker running where you pay attention to your form and leg turnover. Think of your hips like an engine with your feet propelling you forward. A great way to work on stride form is to watch how the elites run and try to mimic what they're doing.
  • Cross-training: Other cardio activities besides running. Great options are swimming, biking, hiking, elliptical, and low-impact aerobics. Stay away from high-impact activities during half marathon training.
  • Intervals: Speedwork meant to improve your anaerobic capacity. To find the paces you are supposed to hit, plug your last race time into an online pace calculator.
  • Taper: The two-week period before the race with lower mileage and intensity that is intended to help your body recover.
