Can't upload large tcx file from activity

Former Member over 9 years ago

Did a 24h TT on the bike, recorded on an Edge 705 so it created a TCX file with power and cadence data, and it is large (38,765,958 bytes).

Garmin Express fails to sync a file that big.

Trying to upload it manually via the connect.garmin.com website and it fails with "An error occurred with your upload. Please try again." I've tried this again and again with no luck, even from a very good network connection at work.

What can I do to get it in to GC?

I tried looking for something to convert the .tcx file to .fit (as that would be much smaller) but can't find anything that works (and preserves power and cadence data).

www.tcxconverter.com was the closest I found, but converting it to .fit (4MB) and uploading that file to GC and it just says "Undefined" and a red X.

(The .fit file that the tcxconverter tool produces seems to be ok, I ran it through fit2tcx and the resulting .tcx file looks good. It's just Garmin Connect that doesn't like it.)

I don't want to split it up into smaller chunks as there's no way (I don't think) to combine activities in GC, and I want it as one activity.

Can anyone suggest anything?

OK, I'll take that as a no then.

My secondary plan is to try and write something that can output a suitable .FIT file from the .TCX file (I've already written my own code to pull apart .FIT files from swimming and produce some stats I was after) so I'm familiar with the intricacies of the .FIT file format.

This will be the bare minimum tool for the job, hardly applicable to anything else or useful as a general tool.
