Garmin Forerunner 405 review

Garmin Forerunner 405 review

UPDATE: This model has been discontinued. For information on current models, check out our GPS for runners page.

The Garmin Forerunner 405 is a relatively new incarnation of Garmin’s popular GPS training device. Updating the Forerunner 305, the 405 was released for sale just before the 2008 Boston Marathon.

The Forerunner 405 comes in a couple of different configurations, with and without a heart rate monitor (HRM). A bike speed/cadence sensor and foot pod are available as options.

Before we get to what folks are saying, lets look at the major changes between the 405 and its predecessors:

  • For one thing, the style has changed, with a sleeker and more watch-like appearance. It comes in either green (pictured above) or black.
  • A wireless connection, using ANT+Sport technology, sends data to your computer. No more cables!
  • The touch-sensitive bezel minimizes the need for buttons on the unit.
  • The map screen found on previous Forerunners is gone (it was pretty rudimentary anyway, showing only waypoints and tracks). But hey, who are we kidding? The Forerunner 405 is a runner’s training partner, not a navigation device.

  1. I purchased the Garmin Forerunner 405 a year and a half ago. Needless to say it was the worst purchase of my life. I bought my Garmin 405 for $350 with the heart rate monitor, and it recently had some battery issues. I called support services, and they were very rude, and told me that I need to send it in to get fixed for $90! Apparently, after I sent my watch in to get fixed, I would be given another competely different watch that was restored, which only came with a 90 day warranty. Do not buy this watch!

    • The warranty is a year. Nevertheless, Garmin does allow their support folks to extend this. It would take some time, but it might be worth another call. It may or may not work. You could also ask to elevate it to a supervisor.

  2. Normally I don’t learn post on blogs, but I wish to say that this write-up very forced me to try and do it!
    Your writing style has been surprised me. Thank you, very
    nice post.
