FW 9.73
After my Garmin crashed in the middle of a ride, data seemed fine, except I got a ridiculously high new FTP notification after I ended the ride. Then I noticed that the Training Effect and Load for my 5hr ride are essentially the same as a 30 minute ride I did a couple days ago, with similar average HR.
I've read another thread from the Edge 830 forums that this is a "known issue". Have you guys seen this? From the same thread, this was related to routing back to start (which was I was also doing). What exactly prevents Garmin from just saving a backup of the calculations as a file?
I would probably be shopping for a new brand if it had lost my data, but this is still a significant annoyance, which'll take a few weeks to get over.
