Welcome to our Calculator Page. Don't be surprised if unusual things happen. This should only occur if you forget to enter information, or enter invalid information.

 If the box to the left does not display the time, then your browser does not support the functionality on this page. We apologize for the inconvience. Well, enough of the disclaimers, let's move along.
First, we have our Pace Calculator. Sure, if you run 5 miles in 40 minutes, it's easy to determine you run an average of 8 minutes a mile. But how far is a 15K, and what is your pace if you ran 1 hour, 12 minutes, and 17 seconds? Well, enter 72 minutes, 17 seconds, 15 in the distance and click on Kilometers, then hit Calculate to find out. You find out you ran pretty well, that's a 7:46 pace. Go ahead, try it out.

Ok, now for our Estimator. Let's say I can run a 5K in 23 minutes and 30 seconds. What time should I try for in a 10K? With the Estimator, you see you have a good chance to break 50 minutes!

Don't get overly optimistic with the Estimator. If you are using the Estimator to find out how fast to run a new distance, be conservative. For example, if all you have run are 5K's and you are about to run a 10K, don't put your Best 5K time in. Use an average 5K time to get an average 10K time. Also, this assumes you run all distances the same, most people generally tend towards shorter or longer distances, not both.

Finally, the Rank'er. Hmmm, probably need a better name for this. So, do you run long or short races 'better'? Find out below. Enter a Time and Distance and hit the Rank button. Enter results for other distances. This calculator will put the races in order. With this you can determine which race was your best performance. Just hit the Clear List button to start over.

Hope you enjoyed the calculators. Sorry if anything unusual happened, we hope to get those cleaned up soon. If you have any suggestions, just send us an email. Thanks.

If you hear someone yell "Hey Geek", do you turn around? If so, keep reading. This page is using Javascript to do the calculations. While Javascript has been around for a while, some of the older browsers do not support this. The Estimator and Rank'er use a formula developed by Runner's World. Basically, it assumes a 5% reduction in Pace each time the distance doubles. For the math folks, try T2 = T1 * ((D2/D1)**1.07), where T = time and D = Distance for 1st and 2nd runs.
