Again solved the problem. Thank you very much Christian. 
Although I have been able to correct it in the program code, I will notify the author in SourceForge saying the source.
Edit: Really is not completely solved RC read the speed but not the good value. For instance for the attached file, in the first point
<time>2018-08-23T10:59:05Z</time> .... <gpxtpx:speed>25.45</gpxtpx:speed>
RC shows 40.1399350,-6.0327120,Position 1, 92.0 km/h.
BTW you could help me about how it would be included in the format gpx data of the KCal consumed info?
Neither the author nor I have found the gpx or Garmin tokens to do that.
Thanks in advanced for your support.
