Anyone using/playing with .fit files?

[Graham Samuel]

I’ve just come across these files which are generated by sport apps (such as Garmin and Specialized) and also have health applications. The format appears to be open and was I think originated by Garmin. The SDK is available but not too friendly to a Mac/LC person.

My interest is in extracting suitable data for a .gpx file to show routes and other stats related to bike rides. I believe I could code this in LC but I wondered if anyone else had tried it.

TIA
