Questions
What does a marathon pace calculator work out?
It starts from the finish time you want for the marathon and divides it by the fixed 42.195 km distance. That gives one average pace, which is then stated per mile and per kilometre. This page also spreads the same even pace across seven checkpoints and shows both the elapsed clock at each one and the time taken for the stretch since the previous one.
Why does each row show a segment time as well as a clock?
The arrival clock tells you when you should pass a marker, which is what a pace band gives you. The segment time tells you how long the stretch from the last marker should take, which is the number you need when you are checking a watch lap or planning a fuel stop. Most pace tables print only the clock. This one prints both, recalculated from your own target time.
Is this calculator only for the marathon distance?
Yes. There is no distance field and no distance switch, and the page prints no predicted finish times for other races. Shorter races, the treadmill and trail running are only linked to from the bottom of the page. The seven checkpoints are points inside the marathon, not separate races.
