Is 12 kmph a good running speed?

Running at 12 km/h (about 7.5 mph) can be considered a good speed, especially for recreational runners. This speed reflects a moderate to fast pace that's challenging for many, but it's significantly slower than elite marathoners like Eliud Kipchoge, who run over 13 mph during races. The elite pace often exceeds the capabilities of recreational runners, indicating that 12 km/h is a solid and respectable speed for general fitness and longer distances 1 2 3.

Ultimately, whether 12 km/h is "good" depends on individual goals and fitness levels.
