Would anyone be so kind to send me a .gpx file of one of their rides generated by a gamin product (specifically with heart rate)

Reading between the lines I'm guessing you're planning to compare your own HR to that of another rider over a set course to help track progress?

A good guess  but not quite correct I want to read the raw data output as a CSV file to see exactly how it is formatted when it includes heart rate. The reason for asking garmin users is that I know garmin files are 100% compatible with strava. I have a Bluetooth HRM on its way to me ( which isn't directly supported by strava ), I will be using a different android app and I don't know if strava will throw a fit if the file formatting it produces is different to Garmin. With a genuine Garmin formatted file as a comparison I can see the differences and correct before uploading. My current HRM and watch keeps giving me what I believe to be false peaks so I can't trust it, unless of course I really can get my 41 year old heart to regularly hit 210 as a max  |

Hi Andy
Out of interest, what model Garmin are you using, does the Garmin HR strap not work with it?
The HR spikes occur with all HR monitors. I have trained with Heart rate for 23 years, using different Polar models and Garmin, now using a Garmin 800. The Garmin premium HR strap was the worst for spikes and mis-reading, and it was by far the most expensive.
So don't assume the spikes will disappear, the moisture under the strap, positioning and temperature have the greatest effect on reliable readings. Almost all HR monitors will mis-read early in a ride on a cold morning, downhill into the cool air.

I'm not up to speed with all this tech stuff. What language are you using, is it Klingon?  |

Hi Darbs,
Currently I don't use a garmin I have a cheap argos HRM.
Its not the false spikes per say I am concerned with, what I am concerned with is, after a ride I look at the max and average ( the only 2 details I can get from the watch ) , so the max is false due to a spike which then makes the average unreliable.
As I explained in the earlier post I just want a genuine garmin .gpx file so I can look at the exact file format so I can replicate the format if required when I get a gpx file from my 3rd party android app.
Hi davidp,
It's not quite Klingon, I am just not very good at explaining things without writing war and piece.

Hi Andy I have attached a .gpx file for you to have a look at. Let me know if it doesn't open properly (I haven't tried attaching gpx files on the forum before so I don't know what it will turn out like!) Let me know if there is anything else that you need. Cheers Paul Attachments:

Thank you huge amounts Darbs,
That is exactly what I was after, I can now look at the formatting of how the heart rate info is embedded in the file.
So when my new Bluetooth HRM arrives, I can test its compatibility with strava, if strava doesn't like it then I now know the formatting so I can make strava accept it.

Hi All,
Thanks again Darbs for the gpx file, I did in the end give up with the phone app and bluetooth HRM, it didn't update fast enough ( the update was every 20 seconds ).
However, I did bite the bullet and purchase a garmin 500, so now I can actually see when I am getting false spikes and know what my actual max HR is.

Good move, the Garmins are great bits of kit. A bit of advice that may help for the future, I am not sure what HR strap comes with the 500, but they do wear out after a while. If it is the premium soft strap with the clip-on separate transmitter you may find that the readings get a little unpredicatable after about 6 months. If this occurs I found that replacing the soft strap itself (not the clip-on transmitter) didn't realy make any long term difference. I had much better results buying the cheaper strap with the buit in transimtter. It is cheaper than the premium soft strap part and has never missed a beat in the same time period that I got through 2 of the premium soft straps previousy. If you have a look on the net many other people have gone this route as well. This is the strap I use now. www.chainreactioncycles.com/Models.aspx?ModelID=44119 |

Thanks for the advice, the strap you linked to, appears to be the same as the strap bought at the same time as the garmin. www.handtec.co.uk/satnav-gps.html It worked out something like £1 less to buy them as separate items as it did to purchase the bundle. |
