Pace calculator
Fill in any two of distance, time and pace. The third works itself out as you type.
Race
What it predicts
Put in a race above, a distance with a time or a pace, and this shows what it is worth at every other distance.
Training paces
Train at your current fitness, not your goal.
Goals matter, but it takes time to grow into goal training paces. Put a race you have run recently in the calculator and train at the paces it gives you. When a new race says you have moved up, move your training up with it.
Put in a recent race above and this shows your easy, marathon, threshold, interval and repetition paces.
