RunTex runners: Use this handy pace/distance/time tool to calculate your time, distance covered, or pace by entering the other two values. Distance and pace can be converted between various measurements. It's a 3-in-1 training device! For best results use the "miles" for distance. For example, to calculate your 10K pace, type in your time, then type in 6.2, and select miles for distance.

RunTex Race Performance Predictor

Use the Prediction Calculator to estimate your performance at any distance. Start by choosing your best race time for a mile or 5K: select the distance of a previous race using the pull-down menu labeled "Distance Run". Then enter the time for that race in the input boxes on the right. Select a different target distance using the pull-down menu labeled "New Distance". Fill in only the 3 areas bordered in blue (Actual Time fields). Then press "Calculate".
