   I murdered myself last night on a climb, and it didn't pick it up, thats using a garmin and importing it via the strava website. I was gutted...

   What's the usual accuracy of GPS on a Garmin, or smartphone? (Garmin say within 15 metres http://www8.garmin.com/aboutGPS/).

   And Strava must have some kind of parameter built into the code to define when two tracks within a certain degree of closeness are, or are not, regarded as riding the same segment.

   I guess if for some reason the trace recorded doesn't pass near enough to the 'official' start/end point, the segment won't get credited.

   It's just a toy IMO.

   I had this recently.. I road up coxgrove hill which appears to have 2 segments logged against it.. Mine only registered the 1 being 'coxgrove alternative'

   The most common reason a segment doesn’t match on a ride or run is because of GPS drift that occurred during recording of your activity. When we determine that a segment matches your activity, we look first at the start and endpoints, and make sure your data passes through those zones. Second, we make sure that at least 75% of the data in between matches the segment data. If any of these cases come up false, the segment will not match your activity or appear on your activity.

   To say I rode this would be a massive lie! Still all KOMs count

   So then, has anyone reported people for iffy segments/times?

   I'm no speed demon but this bloke is 6 seconds faster than me over 0.4 mile segment which isnt outside the realms of possibility but does43.8MPH sounds fishy to anyone else?

   How do they define a 'match'? There's the rub.

   I've been using it now. It really is quite addictive. I've got a few KOM's on the MTB, mostly on the downward stuff, I don't really pay much attention to the start/finish points, so some of my times are all over the place.

   My work commute also seem to be used as a training route by some animal roadies too. I'm not slow I don't think, i'd go so far as i'm probably at the fast end of the average scale now due to increasing fitness, yet i'm being chopped to bits by a select few. I did a bit of Googling & found out most of them race Cat 2, so that's probably what's doing it.

   Still, give me something to aim for.

    Look a bit closer at the map with Satellite on for both of you.
    His track has stopped a fair bit sooner.

    As someone said above it's a toy when "racing" against others.

    I'm doing my best to wear the HR for all rides and runs this year and im getting some interesting stats.

    209 is my highest suffer score on the windmill hill brutal 10k run! a fair bit higher than some of my 3 lap mtb races which also hurt

    So has anyone got any EPIC suffer scores to share?

    There was a code floating around for a 3 month premium membership, otherwise yes, I think you do.

    I've got a couple KOM in a few sections i've ridden and a few top 20 of 160ish people who've ridden the same trail so I'm happy

    You're 5th, that didn't last...

    I've not, but I've seen people who have been. One of the trails in the Surrey Hills has a very dubious leader - 30 seconds quicker than 2nd...

    how would they fiddle that - downhillish & off road ?

    surely people don't edit all their waypoints ?

    I'd be amazed if that time was right, considering Roo is pretty much at the top of all the leaderboards, to put 30s into someone on that track isn't really feasable.

    He doesn't look to be a very fast rider either, the ride that segment was from was 17 miles in 2 hours or something. He's got some weird KOMs though it must be said.

    But yes, it seems highly dubious that the gap between 1st and 2nd is the same as between 2nd and 153rd...!

    exactly... that weekly chain gang is getting faster every week

    Hugo Humphries is a decent Junior racer, good target.

    I don't find the "explore" section of Strava very good, it never shows all the routes and its not very easy to find them....

    Agree there. The map window is too small, it only shows routes/segments if they are contained entirely within the (too small) map, and some of the time it only displays a start/end marker but no actual route.
