Frequently Asked Questions
Is 16 weeks enough to train for a marathon?
16 weeks is the most popular and recommended marathon training duration. It provides enough time to safely build endurance while being short enough to maintain motivation. This is perfect for both beginners with some running base (10-15 miles/week) and experienced runners looking to PR.
What should my weekly mileage be in a 16 week marathon plan?
A typical 16 week plan starts at 15-20 miles per week and gradually builds to a peak of 35-50 miles around week 12-13, depending on your experience level. Beginners might peak at 30-40 miles, while advanced runners might reach 50-60 miles. Our AI coach personalizes this based on your current fitness.
When should I start my long runs in a 16 week marathon plan?
Long runs typically start around 8-10 miles in week 1 and gradually build to 18-22 miles by week 12-13. The final long run before the taper is usually 2-3 weeks before race day to allow proper recovery. We increase long run distance by 1-2 miles each week, with periodic cutback weeks.
Can beginners use a 16 week marathon training plan?
Yes! 16 weeks is actually ideal for first-time marathoners who already run 10-15 miles per week consistently. If you're starting from zero, we recommend building a base first with a couch-to-5K program, then transitioning to this plan. Our AI will assess your readiness and adjust accordingly.
What's the difference between a 12-week and 16-week marathon plan?
A 16-week plan allows more gradual mileage increases (safer for injury prevention), more time to build endurance, and better mental preparation. A 12-week plan is more intensive and better suited for experienced runners with an existing base. For most people, especially first-timers, 16 weeks is the better choice.
Do I need a rest day in a 16 week marathon training plan?
Yes! Rest days are crucial for recovery and adaptation. Most 16-week plans include 1-2 rest days per week, especially after long runs or hard workouts. Our AI coach strategically places rest days based on your training load, work schedule, and recovery needs.
