Gear Review: Garmin Forerunner 405CX

Brand: Garmin

Model: Forerunner 405CX

Battery Life: 8 hours

Whether you are training for a race or just like to run for fun, it’s nice to be able to track how far you’re running. Garmin’s 405cx is a good and relatively price effective way to keep track of your mileage, but it also tracks elevation, average and current running pace, maps your route using GPS, and, if you have the monitor or cadence sensor, your heart rate and cadence.

In the month that I’ve been running with the 405CX it has worked well to help me track my progress and see how my training is paying off. A nice added feature of owning a Garmin watch is Garmin Connect, a web-based program that stores all of your runs and can be very helpful. You can see the GPS routes of each of your runs, mile splits, and calories burned, along with graphs of your pace, elevation, heart rate, and cadence.

The 405CX has three screens that you can customize with up to three data fields each, and a touch bezel wrapping the screen that lets you control everything by using a single tap to select or sliding your finger on it to scroll. There are also two side buttons. One for starting and stopping a run and a second for lapping or resetting after a run. The physical buttons are a nice because any sweat or moisture on your fingers can make the touch bezel really hard to use.

The watch is comfortable to wear for any amount of time or distance, and comes with an option of two different straps for customizing how the watch feels. I prefer the velcro strap as it’s more precise in how tight it fits on my wrist.

In all I would have to say this product has lived up to what I needed and expected.


  • Customizable data
  • One size fits all
  • GPS tracking
  • Elevation mapping


  • Any moisture on  hands makes it hard to use the touch bezel
  • Finding satellites can take a while
  • The distance isn’t always accurate
  • Running through tunnels loses satellite reception
