Overview
The marathon is a long-distance foot race with an official distance of 42.195 kilometers (26 miles 385 yards). It is one of the most challenging endurance events in athletics and a cornerstone of distance running competitions worldwide.
Marathon running has evolved from its ancient Greek origins to become one of the most popular recreational and competitive sports globally, with millions of participants completing marathons each year in cities around the world.
History and Origins
The marathon commemorates the legendary run of the Greek soldier Pheidippides from the battlefield of Marathon to Athens in 490 BC to announce the Greek victory over the Persians.
Ancient Origins
According to legend, Pheidippides ran approximately 25 miles from Marathon to Athens to deliver news of the military victory. Upon reaching Athens, he is said to have exclaimed "We have won!" before collapsing and dying from exhaustion.
Modern Olympic Revival
The modern marathon was introduced at the first modern Olympic Games in Athens in 1896:
- The race followed the route from Marathon to Athens
- Greek runner Spyridon Louis won the inaugural Olympic marathon
- The distance was approximately 40 kilometers
- Early marathons varied in distance between 40-42.75 km
Standardization of Distance
The current marathon distance was established during the 1908 London Olympics:
- The race started at Windsor Castle
- Runners finished at the Olympic Stadium in London
- The exact distance measured 26 miles and 385 yards
- This distance became the official standard in 1921

Training and Preparation
Marathon training requires systematic preparation over several months to build the necessary endurance, strength, and mental resilience.
Training Components
Successful marathon training incorporates multiple elements:
- Base Building
- Gradual increase in weekly mileage to establish aerobic fitness foundation through easy-paced runs.
- Long Runs
-
Weekly runs that progressively increase in distance to build endurance.
- Steady Long Runs
- Maintained at conversational pace for time on feet
- Progressive Long Runs
- Start easy and finish at marathon pace or faster
- Speed Work
-
Intervals and tempo runs to improve lactate threshold and running economy.
- Tempo Runs
- Sustained efforts at comfortably hard pace
- Interval Training
- Short, intense efforts with recovery periods
- Recovery
- Easy runs and rest days that allow adaptation while preventing overtraining.
- Cross Training
- Supplementary activities like cycling, swimming, or strength training to maintain fitness while reducing running impact.
Training Schedule
Most marathon training programs follow a 16-20 week progression:
- Base building phase (4-8 weeks)
- Build-up phase (6-8 weeks)
- Introduction of tempo runs
- Gradual long run progression
- Speed work integration
- Peak training phase (2-3 weeks)
- Taper phase (2-3 weeks)
Physiology and Performance
Marathon running demands exceptional cardiovascular endurance and metabolic efficiency from the human body.
Energy Systems
Marathon performance relies primarily on aerobic metabolism:
- Approximately 98% aerobic energy contribution
- Efficient fat oxidation becomes crucial
- Glycogen depletion typically occurs around mile 20
- Strategic carbohydrate fueling helps maintain pace
Key Physiological Factors
Several physiological parameters determine marathon performance:
| Parameter | Elite Men | Elite Women | Recreational Runners |
|---|---|---|---|
| VO2 Max (ml/kg/min) | 70-85 | 65-75 | 35-55 |
| Lactate Threshold | 85-90% VO2 Max | 82-87% VO2 Max | 65-80% VO2 Max |
| Running Economy | 180-200 ml O2/kg/km | 185-210 ml O2/kg/km | 200-250 ml O2/kg/km |
| Body Fat % | 5-10% | 10-15% | Variable |
Nutrition and Fueling
Proper nutrition strategy is essential for marathon success, both in training and on race day.
Pre-Race Nutrition
Carbohydrate loading helps maximize glycogen stores:
- Begin 3-4 days before the race
- Increase carbohydrate intake to 8-10g per kg body weight
- Reduce training volume during this period
- Focus on familiar, easily digestible foods
Race Day Fueling
Strategic fueling during the race helps maintain energy levels:
- Begin fueling after 60-90 minutes of running
- Consume 30-60g carbohydrates per hour
- Use practiced fueling strategies from training
- Maintain hydration without overdrinking
- Drink to thirst
- Include electrolytes in longer events
- Practice drinking while running
Health Benefits and Risks
Marathon running provides significant health benefits while also presenting certain risks that require careful management.
Health Benefits
Regular marathon training offers numerous physiological and psychological benefits:
- Improved cardiovascular health and reduced heart disease risk
- Enhanced insulin sensitivity and glucose metabolism
- Stronger bones and reduced osteoporosis risk
- Better mental health and stress management
- Increased longevity and quality of life
Injury Prevention
Common strategies to minimize injury risk include:
- Gradual training progression
- Proper footwear selection and replacement
- Strength training and cross-training
- Adequate recovery and sleep
- Attention to early warning signs of overuse
Cultural Impact
The marathon has transcended its athletic origins to become a powerful cultural phenomenon representing human endurance, determination, and achievement.
Modern city marathons serve as major community events, raising millions for charitable causes while bringing together runners of all abilities in celebration of personal accomplishment and collective participation in this ultimate test of human endurance.
