Running Pace Calculator
Calculate pace, finish time, or distance for running and cycling. Includes mile/km splits table, preset race distances, and imperial/metric support.
About Running Pace Calculator
Punch in any two of three variables — pace, distance, or finish time — and the calculator works out the third in seconds. Planning a marathon? Enter your goal time and get the per-mile or per-kilometer pace you need to hold. Training by feel and curious how a recent run translates to a half-marathon finish? It handles that too. Preset race distances cover everything from a 5K to an ultramarathon, and imperial/metric switching means you don't have to do any unit math yourself.
The split table is where it earns its keep. Once the calculator runs, it generates a full mile-by-mile or kilometer-by-kilometer breakdown — useful for writing splits on your hand before a race or checking whether a negative-split strategy is realistic. It works just as well for cycling, so commuters and weekend riders aren't left out.
It lives in Health & Fitness alongside other training tools, and if you want to match your calorie burn to your mileage, TDEE Calculator is worth a look. Works best on a phone the morning of a race, with your target time already in mind.
