Garmin and Polar Data Files
Hey there... I use a Forerunner 301, I don't think I know of software that does what you want. However, I'm not sure exactly what you mean... and I'm curious.
Do you want to train with the polar and the garmin at the same time, and have something that can combine the data collected by both? I'm curious what data they don't have in common.... (yes, I am somewhat of an electronics geek sometimes). I'm guessing the Polar has some bike stuff the Garmin lacks? And the Garmin has the whole "GPS" and usable while running parts?

Yup, that's what I want. The Polar has all the bike info, Power, Cadence, Pedaling L-R, etc. Also, Polar uses a Barometric Altimeter, rather than a GPS Version, seems to be more accurate for elevation.
What I am after is that if I use the Forerunner, I have a way to pull some of the data, say HR Info, into a common Log.
What I'm looking at is to write a VBA program to read in the Garmin HST File, pick a date, then translate the HR and Lap Data into a Polar HR FIle. Big problem is that it looks like Garmin doesn't use a standard sample rate. I'll keep TriFuel posted on the outcome of this coding effort.

That's interesting that the log isn't consistent....
Doesn't the polar have HR? Why do you want the Garmin version?
And yeah, sounds like you'll have to code something. However, if I remember right, the Garmin data is xml. Instead of VBA, would xslt be a way to get just the parts of the data that you want into another file and format?

Greyhound,
Using a 3rd party training software such as Training Peaks, you are able to upload the Polar and Garmin heart-rate files into a common log. I'm not sure if Training Peaks accepts other information such as GPS data sets.
In addition, I do not believe that you would have the capability to combine the Polar and Garmin files into a single workout record. So, the files would show up as two workouts - which may defeat your ultimate purpose.
I've e-mailed Dirk Friel at Training Peaks in the past and he is a great resource. He may be able to point you in the right direction.
Good Luck!

I have not used the garmin301, but the other garmin units that I have used allow you to set the sample rate based on a time interval or a distance interval. The distance interval may account for the irregular sampling interval.

Here's the items I was trying...
1) Use the Polar or the Garmin, and store the HR data in a common database.
Still haven't found a solution to this, I am looking at Training Peaks, and I don't really need to keep the GPS data outside of the Garmin Program.
2) Write a program to convert the Garmin HR data to Polar data.
After looking at multiple Garmin data sets, it still looks like the same rate is variable. That means interpolating HR data, and I don't want to go there.
3) Eventually convert to the Garmin for running, and the Polar for cycling.
The Garmin is pretty cool for running outdoors, and the Polar has all the cool data from the Power Meter for training.
So, what I've decided to do, is keep the Polar, and use it for HR data, and just buy a Garmin 201, which will give me the realtime Pace and Distance, I can store the GPS data within the Garmin program, and use the GPS locations and time to help validate the HR data I'm seeing on the Polar. This is easier ( and cheaper ), than trying to write my own code.
I did some surfing around the GPS sites on the Web, and there were several others who have looked at this, and backed away. Polar doesn't seem to be interested in going to the GPS and HR in the same platform.
Nothing going on today, maybe 3 or 4, after 18 yesterday....

Hey Yall,
I've bought my wife a Forerunner 301, pretty cool, it has the GPS and HRM.
I own a Polar S720, and would like to be able to move data from the Garmin and/or Polar software to a program that will allow me to keep track of all the workouts.
That way, I can buy a Garmin too. I've looked at the files, and I can certianly read the Garmin History file into Excel, and with lots of VBA generate a Polar HRM file.
Anybody done this yet, or know of any other software package that will read both?
Ran 8.5 miles, then rode 13, working on form! :)
