The entrance and explosion of personal GPS units has changed the way we navigate the world. Do you own one? Have you used one. Chances are you’ve at least seen one.

What, then, does this mean for athletes? What does it mean for cyclists?

Here’s what it means: Enhancement. Sport GPS units provide athletes with the opportunity for better benchmarking, tracking and enhancement. Using them adds flexibility and possibility to your cycling workout that you never had before. You can track elevation changes, speed, routes, cadence, heartrate and tons of other variables that can affect your training.

Which one, then, should you use?

This is an important question to answer, as there are many units available. Each unit offers different features making them better for different types of cyclists. I’ll give the most popular units an overview to help you determine which GPS is right for you.

Here’s the rundown:
