GPX to TCS: speed lost

[sebspi]

Hello,

I'm trying to build a TCX file (for Garmin Connect upload and to be able to use the Virtual Partner...) with speed information. Refering to the v2 TCX spec I was expecting something like this:


<Trackpoint>
<Time>2012-08-01T16:15:07.000Z</Time>
<Position>
<LatitudeDegrees>45.3647109400481</LatitudeDegrees>
<LongitudeDegrees>5.9478251449763775</LongitudeDegrees>
</Position>
<AltitudeMeters>329.0</AltitudeMeters>
<DistanceMeters>46.060001373291016</DistanceMeters>
<HeartRateBpm>
<Value>118</Value>
</HeartRateBpm>
<Extensions>
<TPX xmlns="http://www.garmin.com/xmlschemas/ActivityExtension/v2">
<Speed>2.4830000400543213</Speed>
</TPX>
</Extensions>
</Trackpoint>

(speed is in meter/second!)

Unfortunately the tcx file produce does not contain any speed data; whereas saving as GPX I get some speed tags:


<extensions>
<nmea:speed>7.6</nmea:speed>
</extensions>


Is this a bug or a functionality of the TCX format that is not supported? Are there any plans to support this?

Thks,
Best regards,
