Pace Predictor

Ever wonder how long it should really take you to run a half-marathon, or marathon, or even a 1 mile?  OR maybe you'd like to see how you'd compare to Usain Bolt's 9.69 100 meter!! The best predictor of race times is based on the logarithmic decay of pace theory.  The elegance of this method allows accurate extrapolation from a single time/distance data pair.  As a testament, my personal bests are all within 5 seconds of this predictor, all the way from the quarter mile up to the half-marathon!

Here's what you do: Enter an existing race result, then click the compute button to display your known race pace.  Use the drop-down menu's to pick the proper units.  Then enter a new distance and let the computer estimate your target time!  

Have Fun, and provide feedback please!!

Enter an existing, & recent  race result:
Enter the time you ran

Click the button, and your pace/mile will be displayed

:

pace, Min:sec/mile

Now lets try to predict an equivalent time for some other distance
First, I'll need to find out some information specific to you. This customization is based on experience data I've kept over the years. To expand my database, feedback is welcome.

Enter Your age (You may lie if you feel older) : Running Miles per Week:
Rate yourself from Sprinter (=1) to Pure Distance (=5)
Enter New Distance to Predict Race Time: =

Click the button, and your predicted pace/mile will be displayed

: pace, min:sec/mile
