bulk-export run data from Garmin Connect
#!/usr/bin/env ruby
## disconnect
# ./disconnect.rb -u yourusername
# This is a command-line utility for the bulk-downloading of run data from
# the web application, which has lackluster export
# capabilities.
# Using this code is a matter of your own relationship with Garmin Connect
# and their TOS. I can't imagine this being very destructive to their service,
# and it's just filling in a hole in their existing service.
# It's built against Garmin Connect as of July 22, 2011. It's a scraper:
# thus if Garmin changes, this **will break**.
# This script requires all of the utilities on the line below: install them
# with rubygems

Yes! Works perfectly, thanks a lot for the quick reply!

I note the TCX file downloaded does not contain the name or description associated with and activity on the garmin connect website, even though the file format supports that. :-( Can this script be extend to down loads as well?

Yes, thanks a lot for sharing. I also experienced the 400 => Net::HTTPBadRequest problem. Instead of limiting ACTIVITIES_SEARCH to 100, I limited it to 1 and changed the activities function to look like the following:
def activities(agent)
$activityIdx = 0
$numActivities = 624
while $activityIdx <= $numActivities do
puts("Downloading activity = #$activityIdx")
as = ACTIVITIES_SEARCH % $activityIdx
print "\tas: ", as, "\n"
j = agent.get(as)
search = JSON.parse(j.content)
runs = search['results']['activities'].map {|r|
# Get each activity id to insert into the download URL
}.map {|id|
# Download an activity.
download_run(agent, id)
$activityIdx += 1

In my case I wanted all of my history, 624.

Thanks a lot for sharing @tmcw!

Garmin Connect UI has changed and this script no longer works for me.

If you're interested in a Python solution, I have one that does pretty much the same thing (in fact, this script was inspiration for it) and also contains a fix for the new Garmin Connect UI (basically just needs a redirect after login):
