Frequently Asked Questions
How long does it take to train for a marathon?
Most marathon training plans are 16-20 weeks long. However, you should have a base fitness level (running 15-20 miles per week consistently) before starting marathon-specific training. Total preparation including base building can take 6-12 months.
What pace should I run my marathon training runs?
Most marathon training runs should be done at an easy conversational pace (Zone 2), which is typically 1-2 minutes per mile slower than your goal marathon race pace. Only specific workouts (tempo runs, intervals) should be done faster. The 80/20 rule applies: 80% easy, 20% hard.
Should I run a half marathon before a full marathon?
Yes, completing a half marathon before attempting a full marathon is highly recommended. It helps you practice race-day logistics, test your nutrition strategy, and gain confidence. Most coaches recommend having at least one half marathon under your belt before marathon training.
How many days per week should I run when training for a marathon?
Most marathon training plans include 4-5 running days per week. Beginners can succeed with 4 days, while more advanced runners often run 5-6 days. Rest days are crucial for recovery and adaptation. Quality matters more than quantity.
