Advanced running metrics files

[rado93]

hello, i have 2 different devices, 1. watches with basic GPS and HR data and 2. foot running sensor
What do i want?
I want to merge data from those 2 devices so i can upload them as one file to runalyze with extended running meetrics.
What data do i want to merge ?
foot strike pattern ( forefoot, midfoot and heel strike) , landing impact, ground contact time, cadence, step length, eversion excursion, swing angle from my second device
What do i need?
My sensor is using not normalised but it own file format. I am able to create program for translating those data but I need file (or data) from stryd or similar device which produces those values for landing impact etc in normalized data format like tcx or json or alternatively I would like to ask developers of runalyze for xsml schema source for tcx which is able to use those additional running metrics or normalised names for those values inside json file so i can use it as template for conversion of datatype.
Please anybody who does have files with advanced running metrics please comment this topic with attached file or URL link.
I have huawei devices and i will fork existing Hitrava converter for those extra data metrics. Thanks for your help.

The only option is to create fit files with these data (https://developer.garmin.com/fit/overview/) (Fit developer fields)
TCX has by default no options to write running dynamics data. Everyone could extend the tcx easily, but we would need to support this in addition and the Sport standard file type these days is the fit file format.

See attached a fit file of an activity with stryd data. You can upload the fit file at https://runalyze.com/tool/fit-viewer to see a converted version of the content.
We have not yet written a tool ourselves that writes FIT files. It is planned in the future, but is not a priority. Therefore we can not support here.

FitFileRepairTool https://www.fitfilerepairtool.info/ is the tool for that job. But merging two files developers fields, is a time consuming process,

To optimize the merge process you have to have Time synchronized to the second in the two devices or have a common field like HR or Power.

@pepelisbon We do support the merge of an additional fit/activity within Runalyze. Time should be synchronized, but we offer several functions here. But @rado93 would need to have a fit file with this additional developer field.

Thanks for the file and other informations. I will look into it.
