Running Logs: How to Use One to Improve Your Speed, Stamina, and Training

Running logs might remind you of your high school cross-country glory days when you’d whip out your binder and write down your mile splits after a long, hot run in the summer sun. This habit of recording daily mileage is a special moment for some runners. 

For others, this process doesn’t exist. Some just run without taking a minute to take stock in their achievements, assess pain points, and map out a plan for improvement. Running logs are an essential part of any training plan. Those who aren’t actively logging their miles throughout training are doing a disservice to themselves.

Why You Need a Running Log

Running logs provide value in many different ways. Depending on your training and style, you might use a running log in a way that’s different from another runner. However, most would agree that the three most compelling reasons to record mileage in a running log include: tracking your progress, making adjustments to training, and holding yourself accountable.

1. Tracking your progress.

If you didn’t write down yesterday’s mileage, how do you know what you have to beat today? Saving your mile splits in your watch can be cumbersome to retrieve. Running logs lay all your stats out for you in a weekly, monthly, and yearly view. They can show your improvements over time. As you log workouts, your achievements will become more tangible.

2. Making adjustments to training.

Running logs provide a historical catalogue of your past runs. If you fill them out correctly, you should be able to know what workout you did, how long it took, and how you were feeling on a Tuesday six months ago. This enables you to do a comparative analysis to see how weather, terrain, and different types of runs impact your speed, recovery, and overall health. 

No training plan is ever set in stone. With a running log, you can easily make adjustments to your training when necessary and still hit your allotted mileage for the week. This will keep you on track and moving forward despite any setbacks in your way.

3. Holding yourself accountable.

Lastly, running logs help keep yourself accountable. There’s something magical about looking down at your log after a productive week or month of running and seeing every box filled. By keeping a running log, you’ll want to record your day’s work. After seeing how each run builds upon the previous one, you’ll be more incentivized to get after your next workout. Your log will be waiting for you when you get back. You know what you have to do. 

Types of Running Logs

The way runners log their workouts and record their mileage has—like most things—evolved over the years. The only wrong way to log your miles is by simply neglecting the process altogether. Test out different running logs to see which works best for you. Some of the most common ones used are paper logs, digital logs, and mobile apps. 

1. Old-Fashioned Pen and Paper

If you haven’t been religiously keeping one all these years, the phrase “running log” might evoke images of an old binder with papers chaotically exploding from it. Keeping track of your miles in a notebook or on a printed out log is an effective, simple way to get the job done. You can put loose papers in a binder, and start a new sheet at the beginning of each month.

2. Digital Running Logs

If you want to elevate your running log and bring it into the 21st century, consider a digital running log. This can be as simple as a Microsoft Excel spreadsheet, Google doc, or even an online software that allows you to input your mileage, splits, and times. For example, you could use a Garmin Connect and sync the data to your account. After it’s transferred over digitally, you can evaluate and make tweaks to your training program if needed.

3. Mobile Apps

Mobile apps are a quick and easy way to log your miles in just a few taps on your iPhone or Android. Since you likely have your smartphone with you, this makes your running log accessible at any point in time. In addition, there’s plenty of apps that sync to your wearables and even ones that will track your workouts for you as you run. Don’t stop there, though. Download The Run Experience app as a perfect complement to your running log. You’ll find training advice, videos, community, and tips from our dedicated coaches.

5 Key Metrics to Track in Your Running Log

So now that you’re ready to start using a running log, what exactly should you keep track of? Think of your running log as a journal or tracker that captures as much data as possible from your run. This could include your total mileage, run time, mile splits, run type, and run notes.

1. Total Mileage

Recording your total mileage is one of the main aspects of keeping a running log. This helps ensure you reach your weekly mileage and stay on track for your training plan. It also is useful to compare your total mileage on a daily, weekly, or monthly basis to the same period a year prior. This will show how much you’ve progressed or regressed since that time.

2. Total Run Time

You’ll likely remember your PR’s off of the top of your head, but what about everything else? Running logs help bring to light the seconds you’ve shaved off your time for specific training runs. Tracking your total run time helps you understand if you’re getting faster or slower, while providing deeper analysis for other variables that may be impacting your performance.

3. Mile Splits

You can only manage your average pace per mile during a race if you understand your individual mile page. If you’re using a paper running log, record your mile splits on the back of your monthly sheet. This can be a helpful reference tool if you’re doing interval training or another high-intensity workout that requires specific mile or quarter-mile splits.

4. Run Type

Depending on your training program, you could have a variety of different run types that impact your mileage and run time. That’s why it’s important to record what type of training run you’re doing for each entry. Are you running at race pace or doing a recovery run? Is it a timed mile, warm up, or interval training? All of these will impact how you view that specific record months from now.

5. Run Notes

There are so many different variables that can impact your run. What was the weather like? Was the trail flooded? Were you up all night tossing and turning? Have you been wrestling with tendonitis for the last few days? Whatever it is, write it down. Your running log will be more comprehensive and helpful if you include additional details.

Maintaining Your Running Log

In order for your running log to be useful, you must commit to filling it out every day. Running logs with spotty, dirty data won’t help you track performance. Instead, they’ll leave you confused, lost, and even a bit discouraged.

Here are a few tips to making it easier to fill out your running log:

  • Take your log with you to every run. Leave it in your car. It’ll be there waiting.
  • Fill out your running log every day. Use rest days to evaluate your performance.
  • Make it a ritual to fill it out. It should become a part of your daily running routine.
  • Always be 100% truthful. Record your good and bad runs.
  • Take some time at the end of the month to review your performance data.

Once you form the habit of filling out your running log, it should feel weird if you’re ever finishing a run without doing it.

Tracking for Success

Running logs enable runners to track their progress, make adjustments to training, and hold themselves accountable. It can be a useful tool in guiding runners to become the best version of themselves and maximize every run.

No matter how you do it, take some time at the end of every run to record your miles in order to evaluate your performance over time. By doing so, you’ll be continuously challenging yourself to get better, while focusing on your improvements every step of the way.
