Question 1

What is the difference between Pace and Speed?

Accepted Answer

Speed usually refers to how many kilometers you run per hour (km/h), often used on treadmills. Pace refers to how many minutes it takes to run 1 kilometer (or 1 mile). Road runners almost always use pace to track their intensity.

Question 2

What is a typical pace for beginners?

Accepted Answer

• 7:00 - 8:00 min/km: A very easy jog, suitable for absolute beginners.
• 6:00 - 6:30 min/km: Average recreational runner's daily aerobic pace (Zone 2).
• 5:00 - 5:30 min/km: A solid advanced runner.
• Under 4:00 min/km: Elite and highly competitive amateur territory.

Question 3

Is the race time predictor accurate?

Accepted Answer

The prediction is based on a pure mathematical projection of your input pace. In real racing, maintaining a 5K sprint pace for a full 42km marathon is nearly impossible due to glycogen depletion and cardiovascular limits.

Question 4

What is the exact marathon distance?

Accepted Answer

A official Full Marathon (42.195 km / 26.219 miles). A Half Marathon is exactly half: 21.0975 km. Our calculator includes these precise fractions to ensure your time predictions are as accurate as possible.
