Running Time Calculator: Calculates your estimated time for a chosen distance from a known time and distance.Enter your known time in HH:mm:ss and your distance in either km or miles and get your estimated time for a chosen distance.The formula was originally devised by Pete Riegel, a research engineer and marathoner, and published in Runner's World many moons ago by Owen Anderson in 1997. It has stood the test of time since then and has been widely used.The formula is T2 = T1 x (D2/D1)1.06 where T1 is the given time, D1 is the given distance, D2 is the distance to predict a time for, and T2 is the calculated time for D2.
