(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.
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.

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.
