I write turbo training workouts for our cycle club into the 'Workouts' section of my Garmin Connect account. At the moment, the only way I know of sharing them is to send out a copy of the .fit file from the 'workouts' folder on my Garmin 1000, but would LOVE to be able to share them within our Garmin Connect Members group or to my 'connections', in the same way that you can courses. 'Connections' could then send it to their device.
Perhaps if anyone else thinks this would be a valuable addition to Garmin Connect, they might also suggest this to Garmin via the ideas page ;) http://www8.garmin.com/contactUs/ideas/
If anyone knows of a better way of sharing that is currently available, PLEASE let me know :D
Garmin UK support told me that I just had to send out a web link to the workout page in Garmin Connect (to any on my 'connections') but that doesn't work, giving an error saying that 'it looks as though you don't have access privileges to view this file'. Sadly, the UK help desk do seem rather inexperienced when it comes to providing help on such things :( .
