This tool converts treadmill speed settings to running pace, helping you match your outdoor training paces on indoor equipment.
Pace Per Mile: The time it takes to run one mile at your current treadmill speed.
Pace Per Kilometer: The time it takes to run one kilometer at your current speed.
5K and 10K Time: Estimated finish times if you maintain this pace for the entire race distance.
Treadmill running can feel slightly easier than outdoor running at the same pace because:
To simulate outdoor conditions, many coaches recommend setting the treadmill incline to 1-2% for most runs.
This depends on your fitness level and training goal. For easy runs, most runners use 5.0-6.5 mph. For tempo runs, 6.5-8.0 mph is common. For intervals, 8.0-10.0+ mph. Start conservatively and adjust based on your perceived effort.
A 10-minute mile is 6.0 mph on the treadmill. It may feel slightly easier than running 10-minute miles outdoors due to the moving belt and lack of wind resistance. Setting a 1% incline helps simulate outdoor running conditions more accurately.
Calculate your outdoor pace in minutes per mile, then use this formula: Speed (mph) = 60 ÷ pace (minutes per mile). For example, if you run 9-minute miles outdoors, that's 60 ÷ 9 = 6.67 mph on the treadmill.
Most beginners start between 4.0-5.5 mph (12:00-15:00 per mile pace). Focus on maintaining a conversational pace where you can speak in complete sentences. Build speed gradually over weeks and months.
Use whatever unit your treadmill displays. In the United States, treadmills typically show mph. In most other countries, treadmills display km/h. This calculator converts between both for your convenience.
These estimates assume you can maintain the exact same pace for the entire race distance. In reality, factors like fatigue, terrain, weather, nutrition, and pacing strategy affect actual race performance. Use these as general guidelines rather than precise predictions.
