This Runner's World Challenge half-marathon training plan for rookies gradually builds mileage, blending long runs with faster-paced workouts to boost endurance and develop speed.
Key
Rest/XT: Ideally, do no exercise. Nonimpact cross-training like stretching, yoga, or swimming is fine. (Run down? Check out 10 Signs You Need a Rest Day)
EZ Run: Run at a conversational pace or cross-train. When on a bike or rowing or elliptical machine, maintain a sustained aerobic effort.
LSD: Long, slow distance run that builds endurance. Run at a conversational pace. LSDs are rehearsals for race day—use them to determine your gear choices and fueling strategies before and during the run. (Search: Race day nutrition tips)
Tempo: These runs teach your body how to hold a faster pace over time. Do them at a comfortably hard pace, where you can talk in phrases. (Video: Tempo pyramids on the treadmill)
10-K Race: This "tune-up" race is optional. If you choose to do it, use it as a race rehearsal for your half-marathon—practice what you'll wear, eat, and drink, as well as your pacing strategy.
