Right on the money.
Is Strava putting other MTB Riders and the general public at risk?

This looks like a small but hard ride

The right one looks like the Big C. Better get a Check Up.
Self abuser.

that's the difference between a dedicated gps device and one that isn't. gps signal drift - some mtb segments that are near roads, paths etc have a spill over of gps drift that registers these guys as koms or top 10s. not much you can do except create segments that are as close to single track as possible ie good separation from road/path.

I've seen lots of dubious results from iPhones.
Impossible speeds and exaggerated elevation data are very common.
It's worth comparing garmin and iPhone data when 2 guys go for a ride.
The differences are quite striking.

Yep, short segments are pointless, I've found iPhones data can make my segments longer than the garmin as well, particularly on straightish segments. Segments with lots of turns in either the end of the segment or start will simply give KOMs to the people who ride the segment the most and at a fast speed each time, because sooner or later a drift will cause a major part of the segment to be ignored.
The segment drift algorithms used by strava seem to be designed for road segments to be the most accurate, but the downside is they screw up lots and lots of offroad segments . Offroad really needs a different set of parameters .

My personal favourite Strava KOM is a 1.5km hill climb at Smith's Gully which I completed in 3 seconds at an average speed of 1,797.2km/h and a vertical climbing rate of 115,440m per hour. I think that one is safe for a while.

I've seen plenty of dodgy results from Garmins around the Canberra mtb trails - Strava just ain't that accurate so you cant be too precious about it...

Accuracy of Garmin/Strava ETC.
Plot a Garmin course onto a real map of a MTB XC Course and see how many corners you have cut off.
You don't remember cutting all those corners. The 10.8km course is now 8.3kms.
The more corners you turn in a small area (sound like MTB XC) the more room for error.
They are great as a guide only.
You are probably riding much faster than you think.
If you rode the 8.3km course in say 30mins and it was actually 10.8kms. Do the Math.
Enjoy the training.

This Strava thread has shed some light to an awkward situation with my dog – which has seemed very much stressed for a while now.
When I first discovered Strava about a year ago, the first thing I did was to walk around my backyard testing the functionality and GPS tracking abilities. What I did not realise at the time was that I was inadvertently creating a new segment.
Ever since then, I have heard “Strava run!” repeated in the middle of the night. For a long time now I thought it was my crazy neighbour babbling – but now I realise people are obviously jumping my fence and going for KOM in my backyard. No wonder the dog seems on edge all the time.

I've had a few attempts at that one and bugger me how good of a shape were you in??My personal favourite Strava KOM is a 1.5km hill climb at Smith's Gully which I completed in 3 seconds at an average speed of 1,797.2km/h and a vertical climbing rate of 115,440m per hour.

so you could go to this site http://www.digitalepo.com/upload a tcx file tweak it and pick up a few KOMs, what does it mean SFA.

Perhaps this explains those riders at the Youis who seem to be able to ride Cressy faster than Luke Skywalker on his space-bike.
The person who created this little turd deserves a teabagging from Chewbacca. It's almost as bad as "buying your degree online". If anyone else thinks that some self-righteous wanker thinking that sabotaging Strava is going to make the world a safer place, please send an an email to: comments@digitalepo.com telling him/her/them to go piss in someone else's sandpit.
Brings us right back to the original point of this post I guess.
