Practical Example of Half Marathon Pace Calculation
Let’s understand how the calculator works with a real example.
Input Values:
- Distance: 21.097 km
- Finish Time: 2 hours 0 minutes 0 seconds
- Pace Adjustment: 0 sec/km
Step-by-Step Output:
1. Total Time
2 hours = 120 minutes
2. Pace per Kilometer
