What pace do you need to run a 5K?
A 5K is 3.1 miles or exactly 5 kilometers — the most popular race distance in the world and the perfect benchmark for runners at every level. Whether you're chasing a sub-20 personal best or running your first 5K under 30 minutes, knowing your required pace before race day makes all the difference.
The table below covers every common 5K finish time from 14:00 to 50:00. Click any row to load it into the calculator. Highlighted rows mark the most sought-after goal times — sub-20, sub-25, sub-30, and sub-40.
