ecoach overreading distance from GPS
 
Hi,

I am having a problem with eCoach. I record a track, and the .gpx file that is generated is then imported into SportTracks (free sports software with mapping, etc., ).

But, the distance recorded always seems to be too high. A 1km walk becomes 1.5km, every day. I can correct this manually but it's irritating. When I see the map, the drawing of the route is very jumpy, and I am thinking that all the little jumps left and right slightly are adding to the distance considerably.

Has any else experienced this problem? I will try and reduce the GPS update time tomorrow to 20 seconds (it was at 5 seconds). Hopefully it will pick up the run/walk in more straight lines then. I would like to know if anyone else has noticed this, or what settings and software they are using for eCoach.

I use eCoach several times each week for tracking my running. I have the GPS update frequency set to 30sec intervals, and the accuracy seems pretty good. I've mapped the same routes (up to 7.5miles in length) using Google maps and they match eCoach's distance data to one decimal place.

I'll have to check mine because i opened that .gpx file after the running and it shows that i've been crossing larger road last 2k:s in every damn 100 meters. That could cause overreading distance.

I'm going to upload screenshot later and calculate distance from google maps.

Okay. Checked distance from maps and distance is absolutely correct, but map looks like i'm drunk. Anyway, works :D

I'm using Ecoach when running, and it seems to be calculating corrct.

Before N900 I used Nokia SportsTracker, and I still import the running data to Sportstracker. I get the data, but not the map.

Any solutions ?

Hi, You open the dashboard and under your latest workouts you click on Import workout and then you can go to the path on your phone, where the ecoach saves the gpx files.
