I just did a 10 Km run and I wanted to share my Apple Watch work out review with you guys.

The gadgets I used:

- Apple Watch Sport 42mm space gray with Work Out App and iPhone 6
- TomTom Runner Cardio GPS (my first choice for running work outs so far…)
- Garmin Vivo Fit fitness tracker with heart rate monitor chest strap
- Apple iPod nano 6th generation with Nike+ running app

I started with a light warm up run since the optic heart rate sensors of the TomTom Runner and the Apple Watch only work accurate after a couple of minutes.

So here are the results of the different gadgets after the main run:

The measured distance of the Vivofit is way off because you cannot start or stop a certain activity which is why the fitness tracker was unable to tell the difference between warm up, run and all-day activity.
The distance of the iPod nano measured with stride length like the Vivofit is pretty close but still has around 1 Km difference which in my opinion is too much.

The results of the Apple Watch and the TomTom Runner Cardio where pretty similar and very accurate: distance and pace are on the spot (no wonder since this is GPS based).
However there is a really big difference in burnt calories which I still try to figure out and cannot explain so far.

The most surprising fact to me is that all three heart rate monitors where measuring the same heart rate. I did not expect Apple Watch to be so accurate.
It has to be mentioned that the wrist-worn devices need a short time until they get the bpm right.

The Apple Watch battery went from 97% to 66% during the run and the iPhone from 74% to 62%.
TomTom Runner Cardio lost about 1/4 battery and the iPod nano almost none.

The only downside I experienced with Apple Watch during my workout was when it started to rain a little. With a wet watch display and wet fingers you cannot control the watch. You first have to wipe the display pretty dry. But to me that was only a minor flaw.

Verdict: Apple Watch is a pretty precise work out and run tracker when used with an iPhone. I was really surprised...
I can't wait to find out how good the Apple Watch will work when I go on a run without my iPhone...
What also stood out to me is the fact that the Apple Watch is damn comfortable! You don't even feel it's there during the run, it's so light and the band is so soft on the skin! In comparison my TomTom feels like a brick on the wrist...

GREAT WORKOUT COMPANION :)

Nice! Looking forward to ditching my Fitbit Flex. Which of the screenshots is the TomTom and which is the Garmin, btw? Just curious.
 
The pic with the little runner in the header is the my sports-app from the TomTom Runner Cardio.

The AW reports active calories burned (net calories) in the workout app. The tom tom might like most devices/apps report gross/total calories. Go into the Activities app on phone and it shows resting and active calories. Compare that total number with the tomtom to see.
 
From my experience and reading other posts on here it definitely seems the AW is conservative with calories. Even if I look at total calories it's normally about 1/2 of what my Digifit app (reading from my chest strap HRM) shows.
 
However there is a really big difference in burnt calories which I still try to figure out and cannot explain so far.
As a rule of thumb, figure 100 calories/mile. A fit person who runs efficiently will burn less. My Apple Watch had me at about 80-85 calories/mile on today's 10 mile run. My Garmin always overestimated. Since I try to monitor my calorie burn for weight maintenance, I'd prefer the more conservative approach.
 
My 5km run was not so accurate.

Thanks for sharing. I've owned both watches. I sent Tomtom back after realising how uncomfortable it was to wear and that accuracy was only assured once the watch was done up quite tight.

One thing I do miss about Tomtom however is the online results after a work out. The interactive maps allows users to scroll their mouse over the tracks they made while it displays the altitude, heart rate etc, etc at that point of time. It was brilliant. I'm looking for a similar app for the apple watch which I have now. The activity and fitness apps already on the watch don't offer those finer details. Do you know of anything?

Cheers,
CBL
