What is a half marathon?

A half marathon is exactly 21.0975 km โ€“ half the full marathon distance. It is one of the most popular running distances in the world and a perfect stepping stone between 10K and full marathon.

Typical half marathon times

An average recreational runner completes a half marathon in 2:00-2:15 hours. Trained runners finish in 1:30-1:50, while elite runners can run under 1:05 for men and under 1:10 for women. The men's world record is 57:31 by Jacob Kiplimo.

Pacing strategy for half marathon

An even pacing strategy is recommended for the half marathon. Run the first kilometers at your planned pace or slightly slower. Many runners make the mistake of starting too fast. Use the calculator to find your ideal pace and practice maintaining it in training.

Training for a half marathon

A typical half marathon training program lasts 10-14 weeks with 4-5 sessions per week. It should include long runs up to 16-18 km, interval training, tempo runs and easy recovery runs. Remember to taper the last 2 weeks before the race.

Frequently Asked Questions

What is a good half marathon time?

A good half marathon time varies by experience. For recreational runners, under 2 hours is a good goal. Trained runners aim for 1:30-1:50, and elite runners run under 1:10. The most important thing is to set a realistic goal based on your current fitness.

How do I plan my half marathon pace?

Use the calculator to find your pace based on your time goal. A good strategy is to run the first 5 km at your planned pace or 5-10 seconds slower. Maintain a steady pace from km 5-15, and push harder in the last kilometers if you have energy left.

Can I use my 10K time to predict my half marathon time?

Yes, a good rule of thumb is to multiply your 10K time by 2.22-2.25 to estimate your half marathon time. For example: 50 min x 2.22 = approx. 1:51. However, it depends on your endurance and training โ€“ some runners maintain pace better over longer distances.
