How to Use the Calculator?: 

Just enter your marathon goal time and press calculate. Split times for various shorter distances will be shown. Try out the world record (2:03:23, Wikipedia) or my personal record (3:54:36). See if you can keep up with the pace.

The prediction is based on the formula developed by Pete Riegel and published first in a slightly different form in Runner's World, August 1977. The formula is T2 = T1 x (D2/D1)^1.06. T2 is the predicted time and D2 is the distance for prediction. T1 is a known time for the distance D1. So in this calculator the D1 is the distance of the marathon (41.195 km) and T1 is the time you set to the fields. T2 is calculated for various distances D2. Just try it out and you see what I mean.
