Tri Obsession: Data and the Droid

It is an understatement to say that triathletes are data obsessed. For the most part we are right up there with the best of them, baseball fans, gamblers, general fans of statistics and probabilities. Triathlon for the most part generates relatively simple data points. However the volume of training and racing creates infinite environments and sets of circumstances for this data. Couple that with the ongoing to desire to improve against the always moving against us clock (both in races and as we age) there is a strong need to see lots of data and how it is progressing.



The data mainly exists in swimming as time and location (so you can calculate speed). Heart rate monitors don't work well in the water. There is no decent way to measure power. In cycling we have time, location, cadence, power and heart rate. Cycling has the holy grail of data. Running is the same as cycling sans power. Though I am hearing that accelerometers which currently determine cadence on the run will soon give power readings.





Interestingly nothing great exists for capturing all this data in a single device. Swimming just needs a stop watch assuming you know the distance you are swimming, very easy in a pool, relatively easy on a marked open water course. There are some devices that count laps and such but not a big deal. Biking has some slick power meters and cadence computers, those coupled with a good heart rate monitor provide data but it's not all easily accessible. Running is a little better since you don't need to pair a heart rate monitor.





The best product out there (which I don't own and can only report on based on my shopping research) is the Garmin Forerunner XT310. This is similar to the Garmin Forerunner 305 except it is compatibly with power meters with the ANT+ technology. However 3 major complaints on this deal. Like the 305 it is like wearing a small brick on your arm. 2 the GPS doesn't function in the water to deliver anything meaningful. Lastly it sets you back 350 bucks and you don't have the power meter (a grand) or a cadence sensor (1oo bucks for the bike and the run) and that is the price without a heart rate sensor.





Now you can go way down the spectrum to the Garmin Foreruner 50. If you buy it at Costco you get a run speed/cadence sensor, a heart rate monitor for $79.99. For $40 more bucks you can pick up the bike speed/cadence sensor. So you have a good portion of data sans power and gps for $120. This is a pretty good deal and it comes with the upload antenna for you PC too. In fact when you compare what you get here for what you don't on the higher end stuff you'll understand why I am still using it. I have Timex Ironman with a heart rate monitor, GPS, and data upload for the computer. No cadence capability (let alone power) on the run or bike and I have to wear a big GPS monitor on my arm and carry the data recorder in my pocket (though I believe Timex finally put the recorder in the watch, not so with the GPS). My wife bought me this for my birthday several years ago for several hundred dollars and it still costs this much with the GPS on your arm and data recorder in the watch. Again not much for the money. So best value in my mind the Forerunner 50 especially since it is the size of a normal watch.

This brings me to my Droid phone made by Verizon/Motorola and the elephant in the room Google. The phone as is has a compass, accelerometer, GPS and level built in. If it could read a HRM and bike Power Meter it would be 99% of the way there and those two things are probably programmable since it has bluetooth and wifi. It's not waterproof and not a watch but my point is that a phone is probably already closer to the holy grail of triathlon data collection (it probably needs to store 24 hours of data too) than what the big companies in the biz, Garmin, Timex and Polar (not to mention Suunto and some others) already put out. Google also has the mapping capabilities on its website with Google Earth to allow you to visually "see" your data. Heck people are giving away an app to calc your exercise using the GPS and accelerometer already. So why doesn't somebody step up and deliver the product that triathlete's and endurance enthusiasts would gladly pay a reasonable price for? I have no idea. But I'd love to see Google shake up this market (admittedly much smaller) like it is doing in the mobile phone market along with Apple and the iPhone. Competition is good for these types of markets.





Happy Training
