If you love working out, running, swimming, doing Tabata or another kind of exercise, you’ll likely need a pace clock to optimize your performance. A pace clock is similar to a stop watch or a timer, but typically has multiple kinds of settings such as countdown mode, countup mode, interval timer mode and more.

When getting a pace clock, the first thing to consider is how and where you’re going to use it. Is it something that is going to remain stationary in the gym or do you need it to be portable and go with you wherever you work out? This will help you determine what size and style of pace clock you need. If the clock is going to be stationary, you’ll need to make sure you can see it clearly from wherever you are working out. If the numbers are too small or not bright enough, for example, you won’t be able to time your workout properly.

Be sure to check the different modes on the pace clock to ensure you have the one you need. For example, if you’re primarily going to be doing interval training and the pace clock doesn’t have an interval mode, it will not be very useful.

If you’re going to be using the pace clock for swimming or another activity where it may get wet, ensure that it is waterproof. In swimming in particular, pace clocks are placed at either ends of the pool and may get splashed frequently with pool water. It’s possible for pace clocks to get wet at the gym as well, such as if a water bottle falls on or near them.

Buying Advice

  • Some pace clocks come with their own remote control, which makes it easy to change settings. Instead of fiddling with the buttons on the clock, you can use the intuitive remote to get the clock set up as you want it. Remotes also make it convenient so you don’t need to be in the same location as the clock when you’re changing it.
  • If you have a portable pace clock, do you know where you will put it during each workout? Some portable pace clocks come with a magnetic spine, which is particularly handy at the gym or in other places where there is a lot of metal. You can simply stick the clock to a machine you’re working out on so you can see it clearly. When you’re done with your workout, you can easily remove it thanks to the magnet.
  • Wearable pace clocks are a good idea for those that also want to track biometrics at the same time. Some wearable pace clocks are similar to smartwatches and have the capacity to keep track of your heart rate in addition to your pace.
  • If you’re concerned about not being able to see the numbers on the clock clearly enough, opt for one that has adjustable brightness levels. This way, you can find a brightness setting that makes it easy for you to glance at the clock and see the time right away without having to squint or slow your pace.
  • Opt for a pace clock that has a protective case, especially if you’ll be moving the clock around and transporting it to different places, such as the gym. This way, if you drop the clock or it falls over, it will not break.
