It is far more useful to think about the effort behind each run than the actual pace. Don't waste time and energy comparing yourself to other people, or worrying about your exact pace. Our training plans all include different runs, which actually require you to train at different paces. If a run is marked as 'easy' then it should feel just that. Sometimes that may be a bit quicker than others, and that is fine. When it comes to faster runs – 'tempo' or interval sessions – you can use our training pace calculator, but always remember these are guideline paces not prescriptions. They can't take into account all the other factors that may determine how you feel, like how well you have eaten, slept or other stresses in your life.
