Today’s run (street): 2.5 miles
There was an article in Tuesday’s New York Times about the accuracy (or should I say, inaccuracy?) of GPS watches. The writer made the same point that I’ve been making for years, that GPS technology does not provide exact measurement. The same can be said for smartphone GPS apps that show lots of metrics and graphics, but also under-count distance. The thing is, if your distance is off, so is everything else, including pace.
I’m a bit of a belt and suspenders guy when it comes to tracking my runs. I use a Garmin FR210 GPS watch to capture my run metrics and route. But later, I usually measure where I had run using Gmaps to get the most accurate distance. This way I can calculate my true pace. Why use the Garmin if I know it’s inaccurate? Good question. But just try taking my Garmin away from me…
This morning I got back outside for my early run and was rewarded with dry roads and mild temperatures. There was wind coming from the north that, when traveling head-on, made things chilly. Most of my route went either south or east so it wasn’t a problem. I managed an average pace, though my PE (perceived effort) was higher than that result. Then again, when you get your performance information from a GPS watch, you never know what to believe!
