Hi Beki,
As you know, I put something on the other thread... but I'll copy that onto here, so it's all in one place.
I bet there's a good solution nowadays, and I await to see if anyone can advise on something really good.
I'm part of a little facebook group. That would be better (IMO) than a googledrive spreadsheet, because it is more social, you can 'chat' and upload photos... and you can upload a spreadsheet too. If you use a smartphone to monitor you runs, like runtastic, you can upload directly to facebook too. But, as I say, there might be better technology out there... I'm a bit behind the times!
Already, I see some interesting replies that look worth looking into. I'll look into those too.
