Boston Marathon Pace Calculator

Boston Marathon Pace CalculatorDevelop the perfect Boston Marathon race strategy by calculating your exact splits for every mile

The Boston Marathon Pace Calculator will help you establish the perfect target race pace over the fabled Boston Marathon hills. The pace calculator will help ensure that all of your hard training for race day isn’t wasted with a poor race strategy.

The Boston Marathon Pace calculator uses the grade and length of each hill on the course to assign each mile a score for difficulty. The ease or difficulty of each mile is then extrapolated to the target pace per mile to ensure an even effort.

The calculator will help make sure that you don’t go out over your head during the fast early miles and allow you to attack the hills and the last 10k of the course.

Plug your goal race time into the pace calculator and get yourself off on the right foot!
