Calculate Pace Per Rep or Per Lap

Use this calculator to determine your pace for individual repetitions or laps:

• Divide your total workout time by the number of reps to find your average pace per rep
• Multiply a target pace by the number of reps to plan your total workout time
• Calculate splits for interval training by dividing your target time by the number of intervals

Common scenarios:

• Planning 400m repeats: If you want to run 8x400m in 20 minutes total, each rep should be 2:30
• Calculating mile splits: For a 5-mile run in 40 minutes, each mile should be 8:00
• Interval training: If you have 45 minutes for 6 intervals, each interval should be 7:30
