Question 1

How do I calculate my marathon pace?

Accepted Answer

Enter your target finish time (e.g., 3 hours 30 minutes) and the distance (26.2 miles or 42.195 km). The calculator instantly computes your required pace per mile or per kilometer. You can also enter your pace and distance to estimate your finish time.

Question 2

What is a negative split in running?
