Hi Lauren, Craig, Andy,

I had a similar (sort of) issue with my Garmin FR110, but shortening the route from the start.

The time was fine, but it started plotting the route about 0.3 miles into the run. This occurred several times, but intermittently.

I downloaded the latest software last week and that seems to have solved the problem.

Hi Lauren,

I also use a 305 and haven't noticed anything like you say except if i stop the watch then start again it can sometimes add a bit of distance(but no time of course) between the stop and start again.

You can use the auto lap option on the Garmin to split every kilometre or mile or whatever to get your pace that way: under Training, Training Options and Auto Lap. On the Good Run Guide itself you can also see your splits when you upload from the garmin using the Auto Generate option even if you havent set your garmin up to do them.

Hi Lauren,
I have the 305 and have had this issue only once.
I dont understand why it happened but at the end of my route I pressed stop and the timer stopped as did all the other readings, but when I uploaded the info onto GRG I noticed it had continued to measure the route right upto my front door.

Check your routes that have been uploaded from your garmin and make sure they end where your run actually ended and not at your front door as happened with me.

If it is doing this then you can delete a section of your route in the 'measure a route' tab on this website.
