Your guide to buying a running watch

Story highlights
  • Running watches with varying functionality are available for every budget
  • We break down watches by brand for basic, intermediate and advanced options

(CNN) If you've been on the fence about buying a running watch, we're here to tell you that it's totally worth it. When you're wearing one, it's almost as if you have your own personal coach. With each run, you'll get updates on how fast you ran each mile, how many calories you burned, where you sped up or slowed down, and more.

Even though the value of a running watch is pretty self-explanatory, there are a number of factors to consider before you pull the trigger and buy one. As Runner's World points out, "there's no 'Golden Rule' for what classifies a watch as basic or advanced, but generally you can expect simpler watches to have fewer added features, greater ease of use, and a much lower dollar sign attached."

To help, we've compiled a list of running watch brands, from the most basic models to the most advanced. That way, you can compare different options and find the one that suits your needs and budget.

Garmin

BASIC: The Garmin Forerunner 25 ($99.99; garmin.com) As a point of clarification, the term "basic" as it's used here doesn't have anything to do with quality — especially when it comes to the Forerunner 25. When we say basic, we're talking about the number of features. When there are fewer functions, the price is typically lower. This particular model tracks distance, pace, steps, heart rate and calories. It connects instantly with Garmin Connect Mobile so that you can share your progress via social media.

INTERMEDIATE: The Garmin Forerunner 735XT ($349.99; garmin.com) If you're looking to track more than just running, this could be the watch for you, designed for running, swimming and cycling. The 735XT has multisport features and wrist-based heart rate measurements, and it also tells you ground contact time balance, stride length, vertical ratio and more. It syncs your progress using Garmin Connect for live tracking and smart notifications.

ADVANCED: The Garmin Forerunner 935 ($499.99; garmin.com) While $500 for a fitness watch might seem like a high price to pay, it's worth the investment for many athletes. The Forerunner 935 has a sophisticated design and weighs just 49 grams, so it fits comfortably on your wrist. And since it's designed for both runners and triathletes, you'd have a lot of trouble outgrowing this device. With so many functions, including a barometer, an altimeter and an electronic compass, you can set off on real adventure and get an accurate idea of hills climbed, steps and much more.

TomTom

In 2011, TomTom partnered with Nike to create a fitness watch. Since then, it's expanded its line to include the Runner, Spark, Touch and Adventurer.

BASIC: TomTom Runner GPS Watch ($129.99; amazon.com) This TomTom GPS watch has an extra-large screen and one-button control for efficient use while training. It measures time, distance, pace and calories burned and gives you live stats as you run. There isn't a built-in heart rate monitor, but you can pair it with an external one to monitor workout intensity,

INTERMEDIATE: TomTom Spark 3 GPS Fitness ($189.99; amazon.com) TomTom calls this watch "music and cardio on your wrist." That's because this tracker plays over 500 songs. When measuring progress, there's a built-in heart rate monitor, GPS tracking and a route exploration feature for checking out new running paths.

ADVANCED: The TomTom Adventurer GPS Multisport Watch ($349.99; tomtom.com) This advanced multisport watch not only looks super cool, with an easy-to-read display, it also has a ton of functions. These include GPS, compass, altimeter, heart rate monitor, integrated music player and more. In addition, it has multiple advanced training modes, such as interval training workouts, and the ability to track hiking, biking, swimming, skiing and more.
