My first runs were recorded via my phone on Runkeeper as I figured out whether I'd stick with running or not. When it was clear that I was going to keep on running and training for longer distances, I asked for a Garmin Forerunner 10 for Christmas. I started off using it just because my phone's battery wouldn't be drained as fast but I loved the data I got from it. I eventually got a Fitbit Flex as well but wearing two watches when I ran got to be tiresome. Enter the Polar M400. I knew I wanted a watch that had both GPS and activity tracking plus was water resistant (my Fitbit Flex died on me when I got caught in a sudden downpour). Plus i wouldn't mind getting extra data (like heart rate tracking) that my Garmin watch wasn't giving me. After doing some research, I decided that the Polar M400 was the best choice for what I needed and wanted so I ordered it from Amazon.
I love my Polar watch! I've been using it for almost 8 months now and it's been encouraging to see my progress. You can read about the heart rate training it offers on a previous post of mine (I used it to train for my fifth half marathon which was an interesting and sometimes frustrating experience).
One of my favorite things about the Polar M400 is that I can sync training targets to it and know what I need to do for my training plan. Besides syncing to my watch, I have it syncing to a Google Calendar so I can see at a glance when I have workouts scheduled without opening up the app. However, I do have to look at the app or my watch for the specific mileage I need to run which would be nice to have on my calendar.
I really like having the activity tracking on my watch since it motivates me to be moving more throughout the day (especially with the inactivity alert when I haven't been active for the last 55 minutes). Since I'm currently marathon training, I have my activity goal set to Level 3 which I hit easily on my running days and have to work on being a little bit more active on my non-running days.
There have been a couple of syncing issues that have popped up since I got my Polar watch, but those were easily fixed when they released firmware fixes. I also had to reset my heart rate monitor (I have the Polar H7 that came with my watch) because it was being detecting by my watch which caused some frustration as I tried to figure out what was wrong and how to fix it.
Overall, I'm really enjoying the Polar M400 and will probably stick with Polar products going forward. I'm been interested in their updated version of the M400, the M430, since it has wrist heart rate monitoring that is suppose to be as accurate as the heart rate strap and a more advanced sleep tracking system. But since I've had my M400 for less than a year and I don't have an extra $200 laying around, I'll be sticking with my watch for now.
What do you use to track your runs?
