longest VLM measurement

right ..just to clarify I'm not stating that the course is wrong because of my garmin....etc etc etc..

just being curious.whose garmin measured the most..........i spent my time running the outside of the course, giving a high 5 to all the kids......and my garmin measured 26.61 miles........so do i get the RW prize for running the longest marathon on sunday image


  • 26.46 - but would have lost signal in Westferry and the tunnel on Lower thames street, so your still in pole position...image
  • No you don't!! Mine showed 26.66,for some reason mine was out of sync with the mile markers fron very early on. Didn't make any difference to me cos I was 20 minutes too slow for a PB anyway!

    My Garmin showed 26.46 miles and I lost signal in the tunnel.... so you're still first image
  • I think I covered about 30 miles on Sunday thanks to TFL being a bit poo.
    And that includes squeezing through the Greenwich foot tunnel with thousands of my sweatiness friends who don't know what a queue is.
    I really fear for the Olympics if this was a test weekend. I'd give them a D-

    I think I must have run the furthest.  As it took me a jolly long time. image
  • Mine was showing .05 of a mile over by about mile 10, .10 by mile 12 and .30 by 18.  Think it finished at about 26.6 something but will check when I get home.  It was really doing my head in!   

    EDIT:  Just remembered I didn't turn it off when I finished and it was still going 20 mins later so it'll have some daft distance on it, had to text my sister to confirm my time ...

  • 26.43 for me Felt longer image. Garmin all over the place in the tunnels. My garmin was out of sync with the mile markers from the first mile. Towards the end of the race when my garmin indicated another mile i still had 2 minutes to run to reach the course mile marker.
  • Mine finished at 26.73......I did try and follow the blue line but it was impossible!

  • Just to add another sample point, mine came to 26.57.

    Laps were turning over about 30m before the mile markers from near the start, but the plot looks good all the way through to South Quay and even follows the road through Westferry tunnel. Then, all over the shop through Canary Wharf before getting back on the roads at Billingsgate Market and through to the end.

    Two years ago at London mine recorded 27.16, I felt like running a bit further to claim an ultra!

  • Just to prove it mine came in at 26.88

    http://connect.garmin.com/activity/170872368 ( sorry my pc is ancient and wont let me do the link any other way

    but still enjoyed the whole day, even tho i seemed to have run further than 26.2miles according to my garmin, well it felt like it anyway lol

    @Liverbird - When I was going through the finish point I overhead two policemen saying "if this is anything to go by for the Olympics - we're f***ked". On some parts it was the "trial" for the security measures etc.

    For me the mile markers were ok but they started to get more "out" around Mile 11/12

  • gutted that i haven't won this competition........i never win anything image

    26.49. I might go back to racing with a watch!
  • 26.92 - I can offer no explanation as to why it is so much higher, but I did stop for some time in the tunnel on the Embankment for a rather futile attempt to stretch out my calves.

    26.43m for me.  My shortest ever VLM!!!
  • So relieved it was not just me! My garmin has 26.45.

  • 26.66 for me, another nearly but not quite! image
  • 26.56 for me image

    The bit in the City is usually a mare for Garmins, though; the Bupa 10,000 goes through there and I'm sure last year I got that course as the best part of 11k when my Garmin went bonkers because of all the high buildings. I got a whole bunch of lap paces in the region of 3.30-3.45/km when the truth was over 4.00.
  • 26.77 miles for me, this was my second London Marathon & both times each mile was about 1.01 on the garmin, so by mile 10 it read 10.1 miles.

    Then you enter the tunnels and around Canery Whalf the distance was about half a mile out.

    For this reason I picked up a tip from a club mate to turn off the autolap and hit the lap button as I passed each mile marker & could see my time for each mile, didn't make me any faster though image

    Apparently I had quite a short race looking at some of these distances. Must have taken a short cut. Didn't help with the time though.

    26.5m Mostly fine till Isle of Dogs. Had me visting all sorts of buildings going through Canary Wharf but looks good all the way to the finish except going up the slip road at Embankment.

    If reality matched intention I'd know I was dreaming
  • Ah Jordie yes i remember someone else posting that tip for the liverpool marathon as they have to run through the mersey tunnel ( if nothing will knock a garmin out its travelling under a tunnel underwater haha )

    however as i'm not very techy i would be scared that I would get it wrong or worse still forget to hit the button lol

    well makes me look good doesnt it saying I ran a little bit longer than the marathon distance hahaha
  • Mine was 26.36. I only noticed it lose signal once, going under the first tunnel.

    It would be interesting to find out which Garmins got closest to the real distance if everyone travelled along the blue line, as the 410 is supposed to have a different GPS chip than some of the others such as the 210.

  • Mine was 26.48miles... lost coverage twice on the route
  • Mine was 26.99 miles and i tried to follow the racing line for most of the run.

    I blame the rhinos and the wombles (running around them).

    Paul's was 26.89 but got no chip time.

    Mine was only about 20 - not sure exactly - because VLM killed my Garmin!!

    26.52 for me.  No consistency in miles - some of the early ones are short, some are long, so can't blame Canary Wharf for my distance being wrong image
  • When I did it (2010) I got 26.12. I was about 1/2 a mile over until mile 23/24 ish, then somehow the garmin got in sync with the mile markers when I went through one of the tunnels. Could have something to do with accidentally having auto pause on (not to be recommended - my finish time turned out to be 11 mins slower than my watch time!)
  • I got 26.71 on my 405. About 0.01 out on the first mile but it went totally bonkers around Canary Wharf! I think I will turn the Autolap off next time.
