Garmin Forerunner 310XT hacks

I’ve been running with a Garmin Forerunner 310XT for about eight months now. I like it pretty well (running with a HR monitor has totally changed my running for the better, but that’s a subject for another post), but there are a couple really annoying things about it, which I’ve been forced to hack workarounds for.

  • For me, the plastic that houses the transponder on the chest strap caused pretty severe chafing. I think this is something that Garmin is aware of; my wife has a previous version from the same series (the 305, I think), and the strap design does seem improved. But for me, the first month or two was pretty terrible. The chafing was awful, and running four days a week, I never had a chance to heal. I tried all different kinds of lube, tried different ways of positioning the monitor (around the center of my chest vs just under my armpits), played with different levels of tightness. What ultimately ended up working for me was this. I wear it around the narrowest part of my chest, with the strap fairly loose. When I’m running more than five or six miles, I use a bit of runner’s glide. And – this has made the biggest difference for me – I wrapped the big hunk of plastic in a couple layers of athletic tape. It still irritates me a bit, but there’s no more bleeding.

  • The watch has this cool feature where you put a little USB nub in your computer, and it’s supposed to auto-download your latest activity as soon as the watch comes into range. This has worked for me maybe five times, tops. Typically, the software doesn’t recognize the watch at all, and for the first few weeks I owned it, I struggled to find a workflow that’d let me store my workouts on my computer. The only way I could make it work consistently is by re-pairing the watch + computer every time I want to download. Here’s what I do when I get back from a run (I use a Mac for this):
    1. Close the Garmin ANT Agent program in the toolbar
    2. Delete the local Garmin data folder: rm -rf ~/Library/Application Support/Garmin
    3. Start the Garmin ANT Agent application
    4. From the Garmin toolbar menu, choose “Pair with New Devices”. Within a few minutes, it’ll start re-syncing

    Aside from the general fact that this it’s Extremely Stupid, the annoying thing about the process is that it takes progressively longer to complete the more workouts you have on your watch (because you’re deleting your local cache, it’s got to download all of them each time). So, every few weeks, I delete all activities from the watch. But before doing so – because I don’t trust Garmin’s “Garmin Connect” online service – I make sure to copy the .tcx files from my local directory to some safe location. That way, I have offline access to my running history if I want it. cp ~/Library/Application Support/Garmin/Devices/xxxxxxxxxxxx/History/* /some/other/location (where “xxxxxxxxxxxx” is your device ID).

    Hi Boone– I’ve been using this same watch for about 6 months. If you just click “pair new devices” every time you have a new workout (even if it’s already checked) it will download. Sometimes it takes all ute or two for the link to establish, but you don’t have to go through any pairing setup. Works every time like that for me now.
