I am aware that the upload from Wahoo (and possibly other 3rd party apps) is temporarily broken due to recent Connect updates/changes in progress (per http://support.wahoofitness.com/entries/26789884-Garmin-Upload-not-Working-Feb-2014).
My issue is that all my indoor cycling activities uploaded over the past few weeks have inaccurate distance on Connect. It is short by nearly 25% on all of them. I use Wahoo Fitness App with ANT+ iPhone dongle and a spd+cad sensor. I have had this setup for years, just recently it started displaying the wrong distance. Bike computer and iPhone (Wahoo) display correct distance. Running seems to upload correct distance.
For example; indoor training 15mi shows up in Connect at 12.74mi, a 10mi is 8.19mi, a 20mi shows 16.46mi and so on.
It seems to have just started in the last week or two. Who can help me with this? Thank you.
