What kind of pace is 13.5 km/h?

Whether 13.5 km/h is fast or easy depends entirely on how far you run it. The table treats it as your race pace for each distance and shows the fitness (VDOT) that implies, the marathon that fitness supports, and the easy pace such a runner would use in training.

Holding the same pace for longer is what makes longer races hard — most runners run a marathon 30–60 seconds per km slower than their 5K pace.

On the treadmill

Set the belt to 13.5 km/h (8.4 mph). Most treadmills adjust in 0.1 steps, so you may need to round. For outdoor-equivalent effort at this speed, many runners add a 1 % incline — see the treadmill pace calculator for the effect of any incline.

FAQ

13.5 km/h: questions

13.5 km/h equals 4:27 per km and 7:09 per mile — a speed of 13.50 km/h or 8.39 mph.

At 13.5 km/h you would finish 5K in 22:13, 10K in 44:27, a half marathon in 1:33:46 and a marathon in 3:07:32.

It depends on the distance. As a 5K race pace, 13.5 km/h corresponds to a VDOT of about 44.0; as a marathon race pace it corresponds to about 51.0. For comparison, many regular recreational runners race 5K somewhere around VDOT 30–45.

Set the treadmill to 13.5 km/h or 8.4 mph. Adding a 1 % incline roughly matches the effort of running the same pace outdoors at moderate to fast speeds.
