In my efforts to prepare for my wife’s 40th birthday wish of us running the DisneyWorld Marathon in January 2012, not only have I been training but looking for tech gadgets to help me do so more effectively and efficiently. The first in this gadget-fitness series was the Sennheiser/Adidas MX 680i Sports earbuds which continue to provide me a worthy musical/sound experience while running/exercising/working out. In this second in my fitness review series, I will be looking at the Timex Ironman Global Trainer w/GPS Technology and heart rate monitor.

My hope is that the Ironman Global Trainer’s integrated GPS capability and wireless heart rate monitor will help me train better and more efficiently by precisely monitoring (and logging) my distance, pace, accent/decent and heart rate while pounding out the miles.

Getting it setup:

Getting the Ironman Global Trainer operational took approximately two hours to fully charge & two minutes to get the various functions working. The watch is durable, lightweight, water resistance to 50 meters and would meet Julie’s gadget squeeze/creek test. If you have done any research on this watch at all, you know it is designed for strenuous multisport athletes and exercise enthusiasts. This Ironman can operate up to  fifteen hours using the integrated GPS and having it linked to the heart rate monitor. The watch can go much longer between charges if the GPS is off and the HRM is not connected.

Pairing the watch to the heart rate monitor was relatively quick and easy as well. Personally, I am not a huge fan of the strap that makes most heart rate monitoring work. I am a minimalistic runner (the less clothes/stuff the better) and the strap pressing tightly around my chest is, at least for me, uncomfortable and constricting. That said, I did test it against the hand grip HRM of our ellipse machine and the Timex Global Trainer matched what the ellipse was telling me almost perfectly.

Look and Feel:

As you can see, the Ironman Global Trainer is not petite by any stretch of the imagination and when you throw in my runners (aka scrawny) wrists, it looks down right huge. While large in size, the watch is relatively lightweight, rugged, and well made. It is about the size of the Garmin 305 but lighter than many of the smaller watches I have owned.

Making it work:

The seven buttons that enable you to operate and control its functions are easy to manipulate and in the classic Ironman configuration.

The buttons on the right side control: (screen) up, enter, and (screen) down/(run/bike/swim) stop/rest.

The buttons on the left side control: (switch) mode, back/power, and Indiglo lighting.

The large center button on the face of the watch controls starting and while timing you if pushed again documents your split times as well. Once you get the hang of how to navigate the various screens and functions, operating the watch is relatively easy.

The large face of the watch enabled Timex to create a large, easy to read display. The display is customizable to display just the data you want/need to see while exercising.

Getting out for a run:

A majority of my runs are down tree lined trails or paths like this or the urban canyons of downtown Seattle. The tree’s canopies, cloud cover and/or tall buildings do not lend itself to great, continuous GPS signal. Even in the best conditions, it took the Ironman Global Trainer quite a long time/distance before locking onto enough satellites to begin tracking my speed and distance. I dislike having to wait before beginning my runs. Waiting 4-5 minutes before my watch is ready to go is unacceptable (at least to me). So, I head off on my run and eventually the GPS kicks in and the watch begins tracking my run.

I have used three other GPS enabled running watches in the past and all have this same limitation that I mentioned above. Even though the tiny GPS antennas manufactures put into small devices have gotten more powerful and sensitive, they still take some amount to time to lock onto the satellites.

Once the Ironman Global Trainer’s GPS becomes operational, it’s quantitative tracking of distance is very good. I compared the distances the watch said I ran to mapmyrun.com to see how accurate the Global Trainer really is. Over a 5 or 6 mile run, the difference between the Ironman GPS Trainer and the website was minimal. Typically the differential was 0.1 or 0.2, easily explained by human error (i.e., inputting the route into Map My Run or noting just where the GPS begins tracking).

The Pace tracking is a bit scattered/variable, bouncing between 7 min-miles and 9 min-miles when my actual speed is more like 8:00 min-miles over the course of a long run. The watch has a ‘smoothing’ function that helps a bit but not a whole lot. Overall, when everything is working correctly my end/average pace seemed reasonable over the whole of my run.

At the beginning of a run, before the watch has locked onto satellites, the watch can (obviously) begin timing you. Once the GPS locks on, the watch begins tracking distance and pace but the disconnect is, that since they did not begin at the same time the watches calculation of average pace is inaccurate. As an example, you begin your run but the GPS tracking starts 4 minutes (0.5 miles) into your run. After a 5 mile, 40 minute run, the watch tells you that you ran 4.5 miles in 40 minutes. Thus, calculating that instead of 8 min-miles, it informs you that you ran just under 9 min-miles….definitely a difference.

Timex’s Ironman Global Trainer w/GPS is more than just a running watch; it can track your hiking, biking and swimming as well. Since I do none of those other activities/sports, I did not test these functions. But whether you are a weekend/part-time or a hardcore professional triathlete, this Ironman would make an ideal digital workout companion.

Hooking the Ironman to your computer:

Connecting the watch to your computer is simple. Plug the USB end into your computer and connect the other end to the back of the watch. Turn the watch on, get it into the ‘PC Sync’ mode, and start the Timex Device Agent 3.0 desktop application and you are ready to download your data or customize the operations of the watch itself.

Timex Device Agent 3.0 is the included software (available via download) that enables you to manage your workout data, tweak your watch to display whatever info you desire, set notifications, etc. Timex was nice enough to create this software for Windows and Mac users alike. The main (two) purposes of the software is data download/export and operational management of the watch.

A great feature of the Timex Ironman Global Trainer’s management software is that it enables you to truly customize/tweak the watch interface, screen layout, data displayed, alerts, etc  quickly, easily, and (best of all) intuitively. In my opinion, the best feature of the watch. Much easier than trying to do the same on the small screen and interface options on the watch itself. Once you adjust things in the application and hit Save, the changes are nearly instantaneously updated to the watch.

Looking at the data:

Timex has partnered with website, TrainingPeaks as the primary interface for viewing/analyzing the workout data from your watch. After the Timex Agent 3.0 downloads your workouts, it then exports them to TrainingPeaks where you can view the data graphically and/or visually in a multitude of ways. While the Agent is very simple to use, the website is a relative complex and powerful tool to analyze your workouts. Hopefully enabling you to better optimize your training. That said, the basic functions of the website are easy to figure out so you can hit the ground running :).

Bottom line:

I have been using this wrist computer on and off for over a couple of months now. Overall, the Timex Ironman Global Trainer with GPS and heart rate monitor works very well (less a few operational limitations due the the miniaturized GPS technology). It’s accuracy, data package, durability, and functionality make an excellent workout companion. At least in terms of training, it is an outstanding wrist computer. As I have mentioned before, I have tried more than a few GPS enable watches over the years and this Ironman betters them in most categories (data types, ease of use, customability, sync software and overall user experience)….and at $360, it should. There are several similar watches for approximately half as much but they are not nearly as smart or tweakable as the Global Trainer. I would profile/characterize the Timex Ironman Global Trainer for someone who is serious and anal retentive about training (aka marathon runner, triathlete, mountain climber, and the like). If hardcore training is your thing, I highly recommend this Ironman trainer.

  2. Nice review. Have you tried any of the apps for smartphones? I have been using quite a few (and need to write up some reviews on them). I would be curious to see how the GPS on a smartphone works versus the Timex. I know phones vary. My Droid X has been the most accurate, while the iPhone the least.

  3. Its not the phone GPS hardware its the app on the phone. The GPS hardware is pretty much the same. So some apps on iPhones will have better accuracy than some apps on a Droid X and vica versa. I know this for a fact as I work for Motorola as an IT Architect but use an iPhone 4 as my personal phone. As do many Motorola employees.

  4. The nice thing about the Android/iOS apps is that you can map the run beforehand and use your phone to help you with directions during the run. While this may not be important when you are running the same route everyday, it helps tremendously when you are running a new route. More so if you are biking a new route.

  5. I just got the Timex Ironman Global Trainer and when I download my workout, I just see the time…I want to see the distance, the pace, the HR, calories burned….Do I need to download one software or 2 softwares…Do i need ti export my workout from Timex to Training Peak…I need HELP! Lol!

  6. I have the watch and like it generally, but the clasp on the watch band is horrific. It digs into wrist skin. I don’t think my wrist should be bloody after a 16 mile run. One would think a watch company like Timex would’ve tested out their watchband.

  7. Absouletly like the watch, so much that I wear it not only during the biking or running. Only problem I could mention is that it take time to lock the GPS signal, 2/3 minutes are needed for that but its OK I guess, until I warm up its locked.

  8. To answer a few questions above, I utilize an app called “runkeeper” on my I-phone. To be honest, the comparison is almost dead on. Like the gentlemen stated above it may be 0.1-0.2 miles off. Over all I have been very satisfied with the watch but I am having a hard time just finding a replacement charging devise. As I get older the screen isn’t easy to read as it once was, but that’s not the watches fault. Enjoy the watch and love your runs. Thank you
