GPS Distance

Hi Guys,

Congratulations to every one that run the Bupa 10k.   It was my first ever run and I loved it.

Did any body use a GPS tracker for the run?  I did and it appeared I did a bit longer than 10 k. (11.6k)  what makes up the increase in distance?  was it all the swerving i did lol

My watch clocked it at 6.27 miles (which Google tells me is 10.0905869 kilometers). Not bad...

An extra 1.6km of swerving shrek? A whole mile. Where did you swerve? Back to the car for something?

Thats what I thought. . . . I know it was hot but I dont think i got lost. 

Thinking about it,  I think that it may have got confused under the bridges

Hi I ran the London Bupa 10000 and i have a Motoactv running watch and it clocked 6.22miles so it was virtually spot on.
but i have read in various forums how some GPS devices can have little hiccups sometimes when measuring (including motoactv)

Can your gps device load the information onto a website so you can analyse where your watch actually thinks it ran...? 

GPS is only accurate to a certain distance around you depending on signal strength, it could be a good few metres out which may only seem a little, but multiply this over a whole course distance and theres your extra mileage.
