Like most situations in life I thought that I had all bases covered in backing the data up to Garmin Connect and RWGPS. However, it turned out that yes it was being backed up but I couldn't access it due to the "private" setting on Garmin which it shouldn't have been?
The same hurdle was with RWGPS but a couple of clicks and it was resolved and the data could be downloaded. Sadly Garmin Connect wasn't as forthcoming!
RWGPS was only a recent backup process and that recovered about 30k miles, which is about right. However, some of the data was coming back into Strava as corrupted data and I ended up with about six pages of KOMs.
Which to be fair I was happy with, but it certainly pissed a lot of people off as the emails came flooding in about my rides being flagged as incorrect data.
But it was Garmin Connect that had the lions share, but again not all of it.
And even backing it up to Strava, Garmin Connect and RWGPS, I still write it in a diary after every single ride and have done for 30 odd years.
So if you'll excuse me I have some box unticking to continue with.......
