I am using your recommended website to convert files from PWX to TCX but I am losing a lot of data. I switched from the Garmin 500 to the timex cycle trainer 2.0 because of the better sensor and price ( The Timex is selling for $130 with HR). The Garmin 500 was too inaccurate for MTB. When I convert the file from PWX to TCX I am losing the altitude barometric data and the laps analysis. Any help on this? Do I need to try a different website? Do I need to modify the TCX file to garmin 500 so your website can read all the data?
