Strava speeds in the hundreds of KM's..What the?
Postby SquareWheels » Tue Feb 26, 2013 6:16 pm
I would love to be able to go a couple of hundred clicks and hour (but since I am a noob on a flatbar I struggle to get to 30kph )
I ride this bridge which has an underpass for cyclists and pedestrians. The road above is freeway with a 100kph limit, and I am suspecting that some folk are turning strava on in the car

1. They shouldn't let recumbent riders / triathletes use Strava.
2. These new PEDs are really getting out of hand.
3.
4. Strava is for hackers?

I've got myself an iPhone 5 with strava app on it.. Time to leave the Garmin at home! More likely, time for a few cups of HTFU for me.. My effort today was rubbish.SquareWheels wrote:I need to get me one of those phones and get some KOM's to freak out my other flatbar buddiesg-boaf wrote:GPS glitch, probably a phone which had dodgy reception and struggled to catch up - hence the high speeds.

On a Garmin 500. So I can only assume it was dodgy info from the satellite.

I had a ride when my edge 500 decided it was 1999... Not willing to "lose" those km from my stats, I had to upload the file, export it in a text format (gpx I think?), edit it with a search&replace, then upload again and delete the 1999 ridesblack wrote:I had a different kind of bad data the other day. Somehow, mid ride my GPS was convinced it was mid 2026 and recorded a ride lasting for over 13 years! Had to go in and edit the file manually to put the correct date back in.

I forgot about that "sugar".

GPS's are good training/tracking tools but you just have to laugh at their antics sometimes.
Flash's piggy back rides don't look like good business. I wonder if he saw my bike.

GPS glitches. They do wonders for the average speed of the ride, though!

Had that too, rode from the middle of the African Sahara to somewhere in Sydney.. At 30+km/h average speed. Don't use Garmin Connect any more.Venus62 wrote:My husband ended up in Russia one morning. Apparently...

And this one is a nice flat sprint segment, although the headwinds and tailwinds can be a few hundred kmh at times. http://app.strava.com/segments/3089781" onclick="window.open(this.href);return false; (Change to satellite view to see where it is).

g-boaf is on the money but I will expand it.g-boaf wrote:GPS glitch, probably a phone which had dodgy reception and struggled to catch up - hence the high speeds. Or some DigitalEPO.
But principally, if you are riding, at, say, 10kph, and then enter a tunnel and accelerate to, say, 30kph, then your GPS is likely to continue plotting your path as it extimates. It will be using the 10kph for that estimation.
When you exit the tunnel and come back into GPS view then it will see that you have changed location from (estimated) way back in the tunnel to well in front of where it was expecting you to be. Depending on how the software on your GPS handles this, you could get some pretty weird results.
I used to deliberately set this sort of scenario up in a 1.6km tunnel in my home city. Enter slowly, speed up to the legal limit and see what it did when I exited. (Then I got a life. )
I have never seen one go to 704kph. But I suppose that the few-metres innacuracy of the GPS location combined with extremely sort reading and calculating intervals built into the software could give, theoretically, no limit of high speed.
I assume that Strava software analyses the raw recorded GPS datastream and does it's own estimating . In which case Strava's software would be the culprit. I don't use Strava but possibly you can change some settings to somethign more sensible.
btw the concurrent use of multiple GPS satellites reduces those GPS innacuracies, but occasionally when conditions are bad it could be relying on only one or two satellites.

Here is one where you can tke a good shortcut: http://app.strava.com/segments/822245. Check the plot of the KOM ride, it misses a reasonable section of the segment, yet still registers.
and check the slowest time on this one: http://app.strava.com/segments/1762073

This is not a GPS issue but an issue with Oksana and her nudie photos promising to marry you and then draining your bank accountVenus62 wrote:My husband ended up in Russia one morning. Apparently...
