Overview of the McMillan Running Calculator

Web Based Running Calculator

The McMillan Running Calculator was developed by long-time distance-running coach Greg McMillan.  The calculator estimates what your race performance would be for varying distances, based on your current race time at any distance.  It's a very easy to use tool, that can be found online, which is designed to improve your fitness above your current race times.  The results from the McMillan Running Calculator also come in an easy to read format, which makes them easy to understand.

The first step in using the McMillan Running Calculator is to choose a recent race distance.  There are a lot of different options available, which suits everyone from sprinters to marathon runners.  You can choose a distance a short as 100 meters, all the way up to a full marathon.  After selecting a distance, you enter in your best race time for that distance and click on the Calculate button.  For your race time, it gives you the option of entering in hours, minutes, and seconds.  Based on your distance and time, it calculates your equivalent race times for all of the race distances available.  It also calculates your pace per mile (which is blank for all race distances less than 1 mile), and your pace per kilometer.  This gives you a goal to shoot for, no matter what distance you plan on running.

When using the McMillan Running Calculator, it's very important to use a current race time and distance.  If you ran a 5 minute mile when you were in peak physical shape 10 years ago, using that now will not be beneficial to you.  Your results will be skewed because you're no longer that physically fit.  The results will most likely be unattainable.  Input a time and distance that you've recently achieved.  If you haven't kept track of this information, I recommend doing that first, instead of using the calculator based on estimations.

The Test
Now it's time to put the McMillan Running Calculator to the test.  I usually go running a couple of times per week, so I decided to start tracking my times and distances, to enter into the calculator.  I ran a mile yesterday in 6 minutes and 37 seconds, so I'll be using that in my test.  I entered my results in the calculator and got the results almost instantly.  Wow, that was fast!  Based on the information I entered, my race time for 2 miles would be 14 minutes, 7 seconds, and 2 tenths of a second (14:07.2), with a pace of 7:03.1 per mile.  For 10 miles my time would be one hour, 19 minutes and 47 seconds, with a pace of 7:59 per mile.  For a marathon, my time would be 3 hours, forty three minutes and 28 seconds, with a pace of 8:32 per mile.  These are just some of the results; this would be a very long article if I went through them all!   Below these results, you get your optimal training paces.  The calculator provides your mile pace and kilometer pace for different endurance and speed workouts.  This is great information for anyone looking to improve as a runner.
The results are designed to advance your fitness above your current race times.  Obviously, the goal is to improve your race times and your overall fitness, not to stay where you're currently at.  Also, be sure to use your current race distance and time.  When entering your time, do not enter in what your goal is.  The results are based on what you can currently achieve.
