Both calculators run independently — change the inputs on either side to compare results.
Running Pace Calculator
Convert any running time and distance into a per-kilometre or per-mile pace, and project your finish time at that pace over standard race distances. The operational tool runners use to set treadmill speeds, design interval workouts, and avoid blowing up by going out too fast on race day.
BMR / TDEE Calculator
Estimate your daily calorie needs using the revised Harris-Benedict equation, then adjust for activity to get your Total Daily Energy Expenditure (TDEE) — the rough number of calories you burn in 24 hours when you eat a maintenance diet. Enter your weight in kilograms, height in centimetres, age, biological sex, and an activity multiplier (sedentary 1.2, lightly active 1.375, moderately active 1.55, very active 1.725, extremely active 1.9). The result is what most nutrition guides call your "maintenance calories" — a starting point for designing a deficit (to lose weight), a surplus (to gain muscle), or a recomposition plan.
