Run Pace Calculator vs Beat Length Calculator

Stuck working out how far you'll go, how long it'll take, or what pace you need? Run Pace Calculator answers it in seconds, and lets you build interval workouts and see exactly how long they'll take before you head out. For runners of every level, from a first 5K to a marathon. CALCULATOR - Enter any two of time, distance, pace or speed and get the rest instantly. - Pace and speed side by side: min/km or min/mile, km/h or mph. - Pace table with the time for every kilometer or mile of your run. - My Distances: marathon, half marathon, 10K, 5K, 10 miles and 30K ready to use, plus up to 20 distances of your own. - My Paces: save your race and training paces and pick them with one tap.

HEART-RATE ZONES - Set your own five zones in bpm, each with a matching pace range. - A step on a heart-rate zone uses that zone's pace, so your totals stay realistic.
