maximum heart rate in beats per minute (BPM) – 220 minus your age is a good rule of thumb. Then try and make sure you don't go above 75 per cent of that maximum while you're training – this will ensure you don't exhaust yourself and dread the next session

as it takes you to run the repetition and walk the last 50 metres of the recovery before starting the next effort. If you're using a heart-rate monitor, don't start the next rep until your heart rate drops to 120 (men) or 130 (women).Check your progress
, consider the pace you ran for your last 10-mile race or half-marathon. This pace is likely to be just below your lactate threshold, or roughly 80 to 85 per cent of your maximum heart rate, says Nick Anderson, the British cross-country coach. An even simpler
