The Power Of Location-Based Data

Anyone who has used Garmin's Forerunner 205 or 305 already understands the power that attaching location data to traditional measurements like distance, speed, time, calories burned, and heart rate can provide. Knowing exactly where you worked hardest, ran fastest (or most slowly), and lets you tailor your workouts to improve for specific distances, conditions, and types of terrain. It gives a complete picture of how you interact with every portion of your run.

Watch Results
Loaded with serious training features, Forerunner 405 continuously monitors your time, distance, pace, calories and heart rate (when paired with heart rate monitor). Each run is stored in memory so you can review and analyze the data to see how you've improved.

The high-sensitivity GPS receiver sustains satellite reception, whether you’re tackling a trail or jogging through the urban canyons of skyscrapers. The Forerunner 405 is water-resistant (IPX7) and can be used outdoors or indoors (with an optional foot pod), making it the ultimate year-round, all-weather training tool.

Forerunner 405 is available with or without a heart rate monitor (see the versions tab) to help you make the most out of your training. Versions with a digital heart rate monitor continuously track heart beats per minute. Train in a certain heart rate zone to improve your fitness level or compare your pace and heart rate to past performance on the same run.

The revolutionary patent-pending touch bezel on the face of the watch makes navigating the options easier than ever. Simply by tapping, holding or running a finger along the bezel, runners can begin a new workout, access their training history or challenge a Virtual Partner. The Forerunner 405 makes training with a Virtual Partner easy and efficient. Runners can adjust the Virtual Partner’s pace without stopping in the middle of a workout, and the Virtual Partner is always on and ready for a challenge.

Run, Sync, Store and Share
One of Garmin's most ambitious decisions has been to approach fitness devices as a total platform with their "ANT + Sport" connectivity system. All of Garmin's new fitness devices, including the Forerunner 405, Edge 605 and 705 bike computers, and Forerunner 50 heart rate monitor watches, will interface wirelessly with any devices that are compatible wiht the "ANT + Sport" protocol, including devices from other manufacturers.

Once you’ve logged the miles, the ANT+Sport wireless technology automatically transfers data to your computer when the Forerunner is in range. No cables, no hookups. The data’s just there, ready for you to analyze, categorize and share through Garmin's online community, Garmin Connect or optional Garmin Training Center software. You can wirelessly send workouts from your computer to Forerunner, too.

Share Wirelessly
With Forerunner 405 you can share your locations, advanced workouts and courses wirelessly with other Forerunner 405 users. Now you can send your favorite workout to your buddy to try, or compete against a friend's recorded course. Sharing data is easy. Just select "transfer" to send your information to nearby units.

Take your training inside with the versatile Forerunner 405. Pair it with an optional foot pod to track your speed, distance and running cadence indoors when a GPS signal is unavailable. This new design clips onto your laces for easy removal and automatically turns on when you start moving. You can also add a speed/cadence bike sensor to track the speed and distance of your cycling workouts.

Be Part of A Community
In 2007, Garmin acquired Motion-based, the largest shared repository of customer-generated gps-based routes, courses and maps. This was a significant move for Garmin to support the gps user community and bring a wealth of route options to gps users. With a simple connection to your computer, you can join a worldwide network of cyclists and outdoor enthusiasts through Garmin Connect our new, one-stop site for data analysis an sharing.

You can also upload to optional Garmin Training Center software for further analysis. Garmin Training Center stores large quanities of workout and ride data. Some of the things you can do are

  • Review your workout data, including pace/speed, distance, time, calories burned; and if available, heart rate, cadence and detailed elevation.
  • View a detailed graph of your workout data, plotted over time or distance.
  • View a map of your workout that shows the exact path you traveled.
  • Categorize your workout history according to type of activity.
  • Review previous workouts, which are saved by day and week.
  • Create customized workouts with specific goals and rest intervals. Then send them to your fitness device.*
  • Schedule workouts for a specific day with calendar.
  • Get custom workout templates designed by the experts at TrainingPeaks.com

By Brian J. Thomas on June 17, 2009

I was originally hesitant to purchase the Garmin Forerunner 405 because of several negative reviews related to the bezel, GPS accuracy and sync issues with a Mac. In the end, my Timex was just not cutting it and I needed an upgrade. After 50 miles, I can say the Forerunner 405 just keeps getting better.

My goals: I'm not a running junkie, but it is my primary method of exercising. I've run 1 marathon and want to run several more in the near future, but I'd like to do much better in my overall times. My specific goal for training is all about improving my average pace over longer distances (I would like to consistently run future marathons under 4 hrs).

My needs: Accurate tracking for distance, total time, current pace, average pace.

My wants: GPS functionality for improved accuracy, logging of actual run, ability to upload data for review and a visual display on the watch that allowed me to track multiple metrics at the same time (time / pace / distance etc).

My concerns: Almost every negative review (1 or 2 star) highlights 3 basic issues:
1) Problems with the bezel
2) Accuracy of GPS
3) Computer Sync (PC or Mac)

Let me address my personal experiences with the above:

1) Bezel: The most common complaint that I noted was people having issues with the bezel during a run. Specifically after they began to perspire, the user was unable to manipulate the bezel. Has this ever happened to me - absolutely - so why is it not an issue... I don't run naked. I simply wipe my finger off on my shirt or shorts and voila, it works!

Update: after two months of using the 405, I have some additional observations. Based on my experiences, I would lower the star rating to 3 stars. The decrease in rating is due to incredibly poor software and support from Garmin. The hardware is still extremely impressive, despite the software failings.

Software and Support:

The Garmin Connect (which allows you to track your training progress) is nothing more than a beta with limited functionality and slow response times. Moreover, it is still very buggy. The software which automatically uploads the computer data to Garmin Connect just suddenly stopped working a month ago.

Hold times to get in touch with Garmin telephone support is 45 minutes. Email support is terrible - it has taken a full MONTH to have two email exchanges with support. All this and the problem has not been fixed.

Moreover, the software is poorly designed. You have to constantly monitor Garmin's website for software updates (there is no "Check for Update" feature). If a problem occurs in the software, there are no features to aid in resolving the problem.


First impressions: the form factor is nice, but you need to be aware that the watch is somewhat "thick". If you are wearing a button down shirt, the 405 will not fit comfortably under a sleeve cuff. However, looking at it from above, it looks like a normal watch. Wearing it while running will probably not draw a second look from other runners. This is also a downside since you want people to notice your shiny new 405.

Setup - this took only a few minutes and was very easy. TThe 405 walks you through a brief tutorial. Overall, setup was very easy.

Navigation - this takes a few minutes to get the hang of.

I previously owned a Forerunner 201 and my husband runs with a 205. What I really like about the 405 is how quickly it finds the satellites and is ready for a run. I also haven't had any issues with reception, which I often had with my 201.

Unfortunately, that's about the only thing that's improved with the 405 in my eyes. Here are my main issues with it:

- There's no way to turn it off. Sure, it goes into a "power save" mode. In this mode, the battery lasts about a week. You're completely draining the battery every week when you could only be using the battery for an hour or so several times a week. Each time a rechargable battery is discharged and recharged, it uses up a cycle of the battery and there are only so many cycles a battery can go through. At this rate, the battery is going to get used up really quickly. This is poor design. (Or perhaps they're hoping to capitalize on the revenue from people having to replace their batteries more often...)

- If you have small wrists, the watchband is too large and can be uncomfortable. I preferred the velcro strap on the 201. The 205/305 models also have the option to purchase a more comfortable strap that fits small wrists better. I contacted Garmin and there is no such option for the 405.

- The touch bezel is overly sensitive. Yes, you can adjust the sensitivity, but then once you do, it's nearly impossible to use it while running because it's not sensitive enough. There's no happy medium. Sorry Garmin, but old-fashioned buttons work better for pushing during activity. I'm constantly accidently getting into "virtual partner" mode while I'm trying to push the lap button.

- The low battery indicator obscures the entire screen.
