Pace Calculator

Running pace is calculated by dividing your total time by your total distance: Pace = Time ÷ Distance. For example, if you run 6.2 miles (a 10K) in 50 minutes, your pace is 50 ÷ 6.2 = 8.06 minutes per mile, which converts to 8 minutes 4 seconds per mile. The calculator above does this instantly by converting your finish time to total seconds first, then dividing by distance, so you avoid the manual minute-to-decimal conversion errors that trip up hand calculations.

Multiply your goal pace (in seconds per mile or km) by your race distance to get total time in seconds, then convert that back to hours, minutes, and seconds. For example, at a 9:00 per mile pace (540 seconds) over a 26.2-mile marathon, total time = 540 × 26.2 = 14,148 seconds, which equals 3 hours, 55 minutes, and 48 seconds. The Find Time mode above runs this same math for any distance and pace combination, including all standard race distances.

To convert a per-mile pace to a per-kilometer pace, divide the pace (in seconds) by 1.60934, since one mile equals 1.60934 kilometers. For example, an 8:00 per mile pace equals 480 seconds ÷ 1.60934 = 298.3 seconds per km, or about 4:58 per km. Going the other direction, multiply a per-km pace in seconds by 1.60934 to get the per-mile equivalent. This calculator displays both units side by side automatically so you never have to do the conversion by hand.

As a rough general guideline (not a medical standard), beginner runners often average 11:00–14:00 per mile, intermediate recreational runners average 9:00–11:00 per mile, and experienced or competitive runners commonly run 6:30–8:30 per mile depending on distance and training level. Elite marathoners run sub-5:00 per mile pace. Pace naturally slows as distance increases, so a runner's 5K pace is always faster than their marathon pace. Individual fitness, terrain, and weather all affect what counts as a 'good' pace for any given person.

A pace calculator lets you reverse-engineer a race strategy before you ever step on the course. If you know your goal finish time for a 5K, 10K, half marathon, or marathon, you can find the exact per-mile or per-km pace you need to hold and then practice running that pace in training runs. Conversely, if you know the pace you can currently sustain, you can predict a realistic finish time for race day. Many runners also use it mid-training to check whether a recent tempo run or long run pace is on track for their goal race.

Pace measures how much time it takes to cover a fixed distance (e.g., minutes per mile or minutes per kilometer), while speed measures how much distance is covered in a fixed time (e.g., miles per hour or km per hour). Runners almost always talk in pace because it directly matches how races are measured and paced out mile by mile, whereas cyclists and drivers typically use speed. The two are mathematically inverse: speed (mph) = 60 ÷ pace (min/mile).
