How do you open a .fit file? It is used by the garmin 800 but I would like to see it before I upload it but cannot figure out how to open it.

They're microsoft access database files, as far as I can tell, but they're password protected. Your best bet is to upload them somewhere and then download the GPX file if you want to look at it - Garmin has no interest in letting you look at it, and will charge you $500 to get the SDK to open it. There are third party password cracker programs out there too you can look into.

thanks. I am going to try to upload it to my garmin and then download it as a gpx

I think mapmyride allows you to import them.

You might be able to use garmin training center as well (that offline thing they bundle) if you want to create a GPX file.

Once my Garmin corrupted a fit file that was important to me. The unit said zero, and when I uploaded it to GConnect, it said the file had nothing useful inside it. I imported it into Golden Cheetah, then saved it as another kind of file (tcx?), and uploaded that. Worked fine.
EDIT: Golden Cheetah is free.
They're microsoft access database files, as far as I can tell, but they're password protected.
How did you determine this? If it's true, I don't think Access has very strong password protection. What I've read is that a fit file is a series of 'messages' like HL-7, for whatever that's worth.

I can't remember how I determined that... tons of googling when I had a corrupted fit file. Garmin's response was "oh well". Eventually, I found something that opened the file and only 1/3 of the ride was there.
I couldn't say whether access has strong PW protection or not, but I have no idea how to bust it. :) I think one of the downloadable utilities that bust fit files open mentioned access.
you can open the fit file with access, btw, and you'll get the PW prompt.

Interesting. Thanks, TrojanHorse. I wonder if you can read them directly with ADO.NET then?

I'm more of an OS5/DB2 guy, you just wooshed over my head.
I'm curious as heck though - try and lemme know. :)

Hmmmm. I don't have access (haha) to any of my fit files from work. And I don't have MS Access at home. :o
I found this online, in a thread on another forum, about a program that 'repairs' corrupted fit files. A few people were asking to have theirs fixed, and it sounds like they corrupted them in more or less the same way I did.
thanks to all who make use of my little fit file repair tool and special thanks for all positive reactions!
I'll be on vacation the next two weeks and leave the current version 1.2.2 of the tool to be downloaded from
The zip file consists of the repair tool (repairfitfile.mde) and a read me file with some explanations.
The tool requires Microsoft Access XP or newer (2003, 2007, 2010). If you don't have Access installed you can download a (free) runtime version - please note the download link in the readme file.
I hope the tool will help you to rescue your valuable activity data in case of a data corruption. If you have questions and/or comments feel free to contact me. Please be patient as I will have no internet access during my vacation (two weeks without bike and without internet access - a real survival training ...).
It would be really handy if I could get GPX files out of the fit files my Garmin writes, without having to move them through Connect first.
