Complete 16-week marathon training plan integrated with pace, calorie, and TSS calculators. Personalized training for every fitness level.

Training for a marathon? This 16-week plan integrates our running calculators to give you personalized paces, calorie estimates, and training load guidance for every workout.

Before You Start

Prerequisites

  • Can currently run 25-30+ km per week comfortably
  • Have completed at least one half marathon (recommended)

Step 1: Enter a recent race (10K or half marathon) into our Running Interval Pace Calculator to get:

  • Easy (E) pace for most runs
  • Marathon (M) pace for race-specific training
  • Threshold (T) pace for tempo work
  • Interval (I) pace for speed development

Step 2: Find your goal time with our Marathon Pace Calculator

Step 3: Estimate race calorie needs with Marathon Calorie Calculator

Race Day Execution

Pacing Strategy

Use our Pace to Marathon Time Calculator to set splits:

SegmentStrategy
0-10K5-10 sec/km slower than goal
10-21KAt goal pace
21-32KAt goal pace, monitor effort
32-42KHold on or push if strong

Nutrition

Your Marathon Calorie Calculator estimate helps plan:

  • 2,500-3,200 calories burned (depending on weight/pace)
  • Target 60-90g carbs per hour during race
  • Start fueling at 45-60 minutes
  • Practice all nutrition in training

Sample Fueling Plan (4-hour marathon)

  • Pre-race (3hr before): 400-500 cal breakfast
  • Mile 6: First gel (25g carbs)
  • Mile 12: Second gel + electrolytes
  • Mile 17: Third gel
  • Mile 22: Fourth gel (if stomach allows)
