  • Interesting - thanks, good to know.

    My mate has being doing 5 and 10k efforts round the Emirates stadium and is getting some pretty fast times which I'm suspicious of. (Yeah, he's quicker than me, and yeah I'm bitter about it).

    I did 12k the other day at a very relaxed pace. I went round the emirates as part of that and on that km segment my pace jumped quite a bit. I definitely wasn't running faster.

    Made me wonder whether there is something going on with the gps round the emirates, or whether as it's a circle, the gps is triangulating and constantly cutting corners and hence giving a quicker time....

    Either way, I've told my mate I'm not accepting his emirates times. (He is also using a phone).

    It's the opposite, it gets terrible GPS lock and thinks you've run further. Instead of running 100m down a road in a straight line it thinks you've jinked 10 or so yards off to the side, then 10 yards off to the other side and all of those inaccuracies build up.

    The GPS lock doesn't affect the time, as that should be static, but if Strava thinks you've gone further than you have in a specific segment of time then it'll think you've gone faster.

    In open country my Garmin Forerunner 935 is very accurate, I can even pick out where I've veered into the road to give people more than 2m distance. Running into work (SE1) it always goes loopy round the back of St Thomas' Hospital and that's before I get to the underpass below Westminster bridge.

    The other think that people are doing on Strava now is a pisstake of the #RossBarkley5k.

    Strava reports/displays moving time for a run, so people are going out and running 5k but doing it as sprints and rests, but the resting time doesn't count. So people are smashing out PB's all over the place (someone did a 12 minute 5k) but the elapsed time is way longer (some over an hour). Also some are doing them down big hills and pausing the activity while they jog back up and recover, then smash it down the hill again.

    Just beware what you see on Strava's "Moving time", always look at "Elapsed time" or the pace graph to see if there are lots of gaps.

  • But Strava shouldn't record this as a pb, although the distance vs moving time looks fast, Strava still uses universal start/stop time for segments and pbs.

    Some nutter in my club did 36 miles in his 10m wide garden. He counted laps but strava says it's about 12 miles less. I don't know what to do with this information, other than conclude my teammate is mental.

    Edit: and of course, the main take away is to take all Strava posts with a pinch of salt. My neighbour for example, seems to ride a very similar pace on the local loops, but was completely surprised to hear that I don't stop on a 40 mile ride, where as they stop quite a lot. It's a minor thing, but it's good to remember that comparing stats only shows so much.

  • I see, get your point about it being the opposite. Thanks, that's useful.
