What is a marathon?

A marathon is 42.195 km โ€“ a distance originating from the Greek legend of the messenger Pheidippides. The marathon is the ultimate endurance test for runners and is the closing discipline at the Olympic Games.

Typical marathon times

An average recreational runner completes a marathon in 4:00-4:30 hours. Trained runners finish in 3:00-3:45, while elite runners can run under 2:10 for men and under 2:20 for women. The men's world record is 2:00:35 by Kelvin Kiptum.

Pacing strategy for marathon

Marathon requires a conservative pacing strategy. Start at your planned pace or 5-10 seconds slower for the first 10 km. Maintain a steady pace from km 10-30, and try to hold your tempo in the final 12 km. Many runners experience "the wall" around km 30-35.

Nutrition during marathon

During a marathon, it is important to consume carbohydrates along the way. Most runners use energy gels or sports drinks every 30-45 minutes. Practice your nutrition strategy in training so you know what your stomach can handle under load.

Frequently Asked Questions

Most marathon training programs last 16-20 weeks with 4-5 sessions per week. It is recommended that you can already run at least 30 km per week before starting a marathon program. Experienced runners can manage in 12-16 weeks.

What is "the wall" in a marathon?

"The wall" is a phenomenon typically occurring around km 30-35, where the body's glycogen stores (carbohydrate reserves) are depleted. The runner experiences sudden severe fatigue, heavy legs and declining pace. You can reduce the risk by running at an appropriate pace, consuming carbohydrates during the race and having a solid training base.

Should I run the full marathon distance in training?

No, most marathon training programs have the longest run at 30-35 km, typically 3 weeks before the marathon. Running the full distance in training increases injury risk and requires long recovery. Your body can handle the 42 km on race day if you have trained well up to 32-35 km.
