Question 1

What is the difference between pace and speed?

Accepted Answer

Pace is time per distance (min/km), speed is distance per time (km/h). Pace = 60 ÷ speed.

Question 2

What pace do I need for a sub-2-hour half marathon?

Accepted Answer

The half marathon is 21.0975 km, so 120 ÷ 21.0975 = 5.688 min, or about 5:41 per km.

Question 3

Why does my treadmill pace feel easier than outside?

Accepted Answer

There is no air resistance and the belt helps leg turnover, so many runners set a 1% incline to come closer to outdoor effort.
