Noticed something odd that just started to happen. I regularly use this feature, so I know that this is new, and likely that someone "fixed" something.
New upload to Connect. Bike ride was 65.59 miles @ 8mph with 1,991 feet of elevation gain. This all displays correct in Connect site.
But then I "Shared" to Facebook, and that post indicates that I just completed a 6,559 mile ride @ 180 mph with 2 feet of elevation gain! That would have been absolutely awesome ... but it's only off by two orders of magnitude.
