What pace is a 40:00 10K?

A 40:00 10K is 4:00/km (6:26/mi), 15.0 km/h.

What pace is a 1:00 10K?

A 1:00 10K is 6:00/km (9:39/mi), 10.0 km/h.

How do I pick a 10K goal time?

Start from a recent race: the equivalent times under the calculator estimate your 10K from it with the Riegel formula. Then use the ladder to see what a minute faster or slower means per km.

These are estimates from the Riegel formula, T2 = T1 × (D2 ÷ D1)^1.06. They assume you’ve trained for the other distance, so treat them as a guide, not a promise.
