Frequently Asked Questions

How do you convert treadmill MPH into minutes per mile pace?

Divide 60 by the treadmill speed in MPH: Pace (decimal minutes) = 60 / Speed. For example, 7.5 MPH = 60 / 7.5 = 8.0 minutes per mile (8:00 min/mi). 6.0 MPH = 10:00 min/mi. 10.0 MPH = 6:00 min/mi.

What is the 1% treadmill incline rule?

A classic study by Jones & Doust (1996) showed that setting a treadmill to a 1.0% incline accurately mimics the energetic and aerodynamic cost of outdoor running at speeds of 7.0 MPH (8:34/mi) or faster, compensating for the lack of outdoor wind resistance.

Why does running on a treadmill often feel harder than outdoor running?

Treadmill running lacks cooling natural outdoor airflow, elevating skin and core body temperature rapidly. Additionally, visual monotony without changing scenery increases perceived exertion (RPE).

What speed is a 4-hour marathon on a treadmill?

To run a sub-4:00 marathon (26.2 miles in 3:59:59), you must maintain an average outdoor pace of 9:09 min/mile, which corresponds to a steady treadmill speed of 6.55 MPH (10.54 km/h).
