Exporting .tcx but no speed data

After eyeballing the xml, the <AltitudeMeters> node is not there either

I also have this problem, have some clues.

Hey,

I've recently had the exact same problem. Last few rides. The last data file for me which had speed data was last tuesday (3-11-15) and a ride the next thursday (3-13-15) did not have speed. I tested the hypothesis that speed needed to be a data field. That was wrong.

I hope this gets fixed, I don't want to have to re-write my stand alone application to inject the speed nodes using the differences in time and distance.

I've attached my last file for which speed was present, and the first file for which it wasn't

Opened ticket with Garmin Support

I opened a ticket with Garmin support. I also poked around this forum and found I wasn't the
only one to hit this problem:

https://forums.garmin.com/showthread.php?220362-Export-to-TCX-Where-s-the-Elevation-Data

The last post in this thread stated that "Garmin was aware of the problem and is working on it" or
something to that effect.

I'm considering downloading a TCX Converter app which is supposed to translate from .fit to .tcx.
if Garmin doesn't fix this problem soon:

I'm a little reluctant to do it though since it might be malware. You never know.

I tried working with Garmin Support to try to resolve this issue.
They wouldn't take my case because my files were created with an
older version of the firmware on my Edge 510.

They tried to get me to install Garmin Express on my Windows XP
box which, according to their system requirements is not one
of the supported OS'es. This move would have, at the least
wasted my time, and at most, crippled my registry with conflicts,
and/or useless entries.


The lack of <AltitudeMeters> nodes in Garmin Connect .tcx exports must be due to
changes in the websites backend processing. Working with
a .fit file that Garmin Connect failed to produce a .tcx
file with altitude with, I was able to produce a .tcx with altitude
using a third party product called TCX Converter:
http://www.tcxconverter.com/TCX_Converter/TCX_Converter_ENG.html

Similarly,
Strava took that same .fit file and was able to report on altitude
which matched the altitude displayed on the 510 for the ride.

The lack of <Speed> nodes in in Garmin Connect .tcx exports is more troubling. TCX Converter
did not recover speed information from rides I took after March 8 2015. Cadence information
is present in these rides, and I use a combination Speed/Cadence sensor so it doesn't make
sense that cadence is present and speed isn't . Prior to March
8th, I hadn't used the Edge 510 for 3 months. When I turned it on on March 8th it took
a while to come up. Looking at the files on the device with Windows Explorer, many
of the files and folders have a Date Modified timestamp equivalent to the time
when I turned it on. Did Garmin try to beam down a code update from a satellite or is
there a date based logic bomb in the firmware? I don't know!



Since I'm not optimistic about Garmin resolving this issue in a timely way,
I'm going to calculate speed in my application.

I'll keep using the 510 until something else breaks which renders it useless.
The only reason I got it in the first place was because it records elevation
that Strava recognizes, which is always greater then the elevation that
Strava calculates for rides recorded with Iphone apps. If it does break,
I'll move back to Cyclemeter.

After data has been pulled from .tcx files into SQL Server here's a solution for calculating speed from distance. The 510 samples every second, the query derives additional meters traveled for each trackpoint node.

========================================================================================================
CREATE PROCEDURE [dbo].[UpdateCalculatedSpeed]
@RID int
AS

CREATE TABLE #TPRaw
(RID int,
DistanceMeters decimal(23,8),
Extensions_Id int)


INSERT INTO #TPRaw
(RID, DistanceMeters, Extensions_Id)
(SELECT
T.RID,T.DistanceMeters,
E.Extensions_Id
FROM
Trackpoint AS T
INNER JOIN
Extensions AS E ON
T.RID = E.RID AND
T.Trackpoint_Id = E.Trackpoint_Id
INNER JOIN
TPX AS TX ON
E.RID = TX.RID AND
E.Extensions_Id = TX.Extensions_Id
WHERE
TX.RID = @RID)


UPDATE TPX
SET CalculatedSpeed = D.MetersPerSecond
FROM
TPX
INNER JOIN
(SELECT
TP2.RID,
TP1.Extensions_Id AS ExId1, TP2.Extensions_Id AS ExId2,
TP2.DistanceMeters AS TP2Meters, TP1.DistanceMeters AS TP1Meters,
CASE
WHEN TP2.Extensions_Id = 0 THEN TP2.DistanceMeters
ELSE (TP2.DistanceMeters - TP1.DistanceMeters)
END AS MetersPerSecond
FROM
#TPRaw AS TP1
RIGHT JOIN
#TPRaw AS TP2 ON
TP2.Extensions_Id = TP1.Extensions_Id + 1) AS D ON
TPX.Extensions_Id = D.ExId2 AND
TPX.RID = D.RID

DROP TABLE #TPRaw

If you don't mind a workaround:

You can download the 'old' Training Center software from Garmin here: http://www8.garmin.com/support/collection.jsp?product=999-99999-04

Import the FIT file and export it again as TCX. It will contain both speed and altitude plus a number of extra data.

Thanks Duposoft.

Someone else has pointed out an online solution that does the same thing:

which worked for me, if I ever want to go back to a recorded speed solution.
