I use mapmyrun and Garmin 610, there is a huge difference in pace calculation between the two, an 8:40 min/mile pace on mapmyrun is actually a 9 min/mile pace on my Garmin, a 5 mile run with Garmin is a 5.25 mile on mapmyrun hence the difference in pace, If you are planning on participating in races you should use a GPS watch which gives you a better estimate of your actual pace, keep in mind that a GPS watch pace is about 5 seconds faster than your real pace.

Garmin all the way. Much more accurate.

^^this. It's not even close. Garmin is a great company with a great product line, imho. Check out DC Rainmaker's site: http://www.dcrainmaker.com/ for comparisons of the different options out there.

Good luck!

I'm happy with my Garmin. I'm even happier to not have to run with my phone.

I have to admit, though... I have a Forerunner 110, and I don't know if it's just this model or what, but sometimes it just dies when I put it on the charger. I've never not been able to resuscitate it, but it pisses me off.

See if there is a firmware upgrade for it.

I use map my run to figure out a new route to run when looking to change up the routine or running in an area thats new to me. Sometimes the same routes get just plain boring.

I have a Garmin 305 and swear by it. So the map my runs helps me create a map and the Garmin tracks it for me while i run (or ride my bike, I have the cadence monitor on my bike....a lovely add on). Love my Garmin...best investment ever.

I use my Garmin 610 and sometimes also use runkeeper on my phone. The runkeeper goes wonky on me when it swaps between wifi and 3G (eg I ran 4 miles, it told me I ran 14.1-through people's homes, across a highway, into a grocery store). Otherwise, the two are generally pretty close. But, I'm very slow-so I'm not making a whole lot of forward progress between satellite pings. I think that helps on the phone side. I generally go with the Garmin data, but even it comes up with significantly varying distances for the same route (as much as 1/2 mile for 4-5 mile run). But it's all close enough for me. I just like the gadgets.

I have the Garmin 910xt and I load all my runs on Strava and they auto upload to Garmin Connect.

I was looking into strava...I didn't realize about the auto upload to GC. Actually, my primary holding place for workouts is Sport Tracks, which I really like. But, I like to have them online, as well.

edit: one thing that isn't great about Sport Tracks is mapping out routes beforehand (you can't), but I find Garmin Connect to be really handy for that.

I used Map My Run before buying my Garmin- found out Map My Run was pretty inaccurate.

I really really love my Garmin. Can't do it without it. I have the Garmin Forerunner 210 with the heart rate monitor. Awesome and simple to use. Doesn't have all the bells and whistles and crazy analysis capabilities, but it serves my needs. It's also not as big as some of the other models. Love that watch to pieces!

Nope. Kind of a moot point now anyway; I already figured out how to deal with its BS. It's not an uncommon problem, either, just weird... sometimes it's like the charger drains the battery entirely rather than charging it.
