Running Tracks and COROS GPS Watches

0

All GPS watches and trackers often lose signals in forests, among tall buildings, and in narrow canyons. When that happens the accuracy of our training data suffers. But when it comes to a running track, with a typical clear view of the sky, we assume that GPS accuracy must be high. Right? Wrong. The running track is one of the worst places for GPS accuracy. The reason is that your body always blocks the GPS signal being received by your watch at some point during the lap so your location gets fuzzy to the device. COROS GPS watches have a proprietary (and patented)  built-in solution.

While Uphill Athletes don’t spend a lot of time on the track, a lot of folks use it for their Heart Rate Drift Tests. Here are some tips for accurate measurements during track workouts or tests:

  • If you have a Coros use their Track Run mode.
  • Verify that your watch is using a track length of 400 meters, not a quarter-mile (which is slightly longer).
  • Define the lane you’re running in.

If no do not have a COROS watch then track run mode is not available to you. If accuracy is paramount, as in a Heart Rate Drift Test, you can try to rig your watch somewhere with an unobstructed view of the sky, such as under a snug fitting hat.
