Step-by-step
- Convert pace to s/km: 300 s/km → 300.0 s/km.
- Convert distance to km: 21.0975 km → 21.098 km.
- Multiply: 300.0 × 21.098 = 6,329 s = 1:45:29.
How to use this calculator
- Enter your goal pace per mile or km.
- Enter the race distance.
- Read the predicted finish time.
About this calculator
Pace × distance = time. The trick is matching units — if your pace is in min/mile and your distance is in km, convert one before multiplying. This calculator does it for you and shows the result formatted as h:mm:ss for races over an hour.
Frequently asked
Compute the finish time at your target average pace, then pace the first half slightly slower. A common negative-split strategy is +5 to +10 sec/km on the first half.
