Training for a marathon from scratch typically takes about 5-6 months with consistent preparation.

Estimated Duration: 150 days

To train for a marathon as a beginner, start with a structured plan that gradually increases mileage. Begin with shorter runs (3-5 miles) 3-4 times a week, incorporating rest days and cross-training. Over 5-6 months, build endurance by increasing long runs weekly (peaking at 18-20 miles). Include speed work, strength training, and proper nutrition. Consistency, recovery, and injury prevention are key. Most beginners complete their first marathon after 20-24 weeks of dedicated training, depending on fitness level and commitment.
