There are two basic ways to keep track of your running—by time or by distance. with so many tech tools designed to track your mileage with considerable accuracy it makes this debate even hotter amongst the running community. Truthfully, there are advantages and disadvantages to each method and the one that you choose should depend on your specified needs and preferences.
Running by time often works better if you are on a tight schedule; while running by distance can push you to stay motivated. If your running a consistent pace, your mileage and speed will likely be the same no matter which method you choose. A good idea is to run by time for each individual run, but be sure to track your overall mileage for the week to be sure that you are running enough miles or not running too many miles.
Running for Time
One reason to run for time is that it is easy to fit a run into your daily routine. When you only have a certain amount of time available, a timed run ensures that you can get in a workout without having to worry about hitting a certain distance.
Running for Distance
If your training for a longer event, running by distance can be an important factor. Covering a certain set number of miles each run can be motivating at times and it encourages you to keep a continuous pace so that you can achieve your day's goal.
As mentioned at the beginning of this article, it is a good idea is to run by time for each individual run, but be sure to track your overall mileage for the week. Personally I like to run 60-75 minutes 6 days a week and then have a specific mileage goal for my long run. But, when things are not feeling easy, it is nice to switch gears and make your long run 2 hours - no set mileage. Time on your feet is what matters, not pace, and not mileage - especially as a beginner.
