5K and 10K Race Pacing
Calculate target pace and splits for your next 5K or 10K.
| 5K | 25:00 |
| 10K | 50:00 |
| Half Marathon | 1:45:29 |
| Marathon | 3:30:59 |
Enter time as MM:SS (e.g. 50:00) or HH:MM:SS for longer efforts. Works for running, walking, cycling, swimming, or rowing — just match the distance unit.
5K / 10K tips
A sub-25-minute 5K needs 5:00/km. A sub-50 10K needs the same pace held twice as long.
Negative splits (second half faster) usually beat going out too hard. Aim to hit goal pace, not exceed it, in the first km.
Use "Find time" with your training pace to set a realistic race goal before signing up.
