How do I convert mph to min/mile on a treadmill?

Divide 60 by the speed in mph. For example, 6 mph gives 60 ÷ 6 = 10:00 min/mile. This tool does that calculation automatically and also shows the equivalent pace in min/km.

What treadmill speed equals a 5-minute kilometer?

A 5:00 min/km pace equals 12 km/h (60 ÷ 5 = 12). On a treadmill calibrated in mph that is approximately 7.46 mph.

What is a good treadmill speed for beginners?

Most beginners run comfortably between 5–7 mph (8–11 km/h), which corresponds to a pace of roughly 8:34–12:00 min/mile or 5:27–7:30 min/km. A conversational effort is more important than hitting a specific number.

Is treadmill pace the same as outdoor pace?

Treadmill pace is generally slightly easier than outdoor pace at the same speed because there is no wind resistance and the belt assists foot turnover. Many runners set treadmill incline to 1% to better approximate outdoor effort.

How accurate are the race finish time estimates?

The finish times assume you maintain the entered speed or pace for the entire race distance without slowing down. Real race performance depends on terrain, weather, and fatigue, so treat these figures as training benchmarks rather than guaranteed results.
