What treadmill speed is a 10 minute mile?

A 10 minute mile is 6.0 mph on a treadmill. Faster speeds produce lower pace times, so 7.5 mph is an 8 minute mile and 5.0 mph is a 12 minute mile.

Does treadmill incline change pace?

The belt speed determines the displayed pace, but incline changes workout effort. Many runners use a small incline for variety, while hill workouts use higher incline settings for strength and effort.
