How To Predict Your Race Time
SIMPLE I use this formula to predict my race time. It's quite accurate. Google "Pete Riegel" for more information. T2=T1*(D2/D1)^1.06 Example 1: If your 5k race time is 20:00. Your 10k race time will be: 20:00 * (10 / 5) ^ 1.06 = 41:42 Example 2: If your 21.1k race time is 1:51:13. Your 10k race time will be: 1:51:13 * (10 / 21.1) ^ 1.06 = 50:24 This formula can apply under most circumstances for the race time prediction between 5km to 42km and if you do not require very accurate timing. However, if you want to be very precise then you might need to read the following sections. ADVANCE Everyone is different The value of 1.06 given for the exponent is quite unachievable for most of the people. It's different for everyone. You will have to experience and adjust the exponent value yourself. For example: mine is somewhere around 1.07~1.08 for most of the time. If you are a sprinter type of runner, then it's maybe somewhere around 1.09~1.10. If you a...
