Frequently Asked Questions
Is 12 weeks enough time to train for a marathon?
Yes, 12 weeks is sufficient for runners with a solid running base (running 15-20 miles per week). However, beginners who have never run before should consider a longer 16-20 week plan to build up safely. Our AI coach will assess your current fitness and recommend the best duration for you.
What is a good base for a 12 week marathon training plan?
Before starting a 12 week marathon training plan, you should be able to comfortably run 15-20 miles per week and complete a long run of 6-8 miles. This base fitness helps prevent injury during the intensive 12-week buildup. If you're not there yet, our system can create a longer plan to help you build this base first.
How many miles per week in a 12 week marathon training plan?
A typical 12 week plan starts at 20-25 miles per week and peaks at 35-45 miles per week around week 9. The exact mileage depends on your experience level and goals. Advanced runners might peak higher, while beginners might peak at 30-35 miles per week.
Can I download a PDF version of the 12 week marathon training plan?
Yes! Our AI Running Coach provides a free downloadable PDF version of your personalized 12 week marathon training plan. After generating your plan, you can export it as a PDF or add it to your calendar. No subscription required.
What pace should I run during a 12 week marathon training plan?
Your training paces depend on your current fitness and goal marathon time. Our AI coach automatically calculates your easy, tempo, and interval paces based on your recent race times and running history. Most runs should be at an easy, conversational pace.
How do I prevent injury during 12 weeks of marathon training?
Key injury prevention strategies include: gradual mileage progression (increase by no more than 10% per week), adequate rest days, proper nutrition and hydration, good running shoes, strength training, and listening to your body. Our plan includes all these elements with built-in rest and recovery weeks.
