I did a workout on Sunday it was a 5 hour bike and then i did a manual change to run off the bike. During the session all appeared correctly and data recorded well. When I ended the session I reset as usual. When i sync'd my 910xt all workouts for last few days went across fine but the sunday workout will not sync on express. I checked my laptop and the file appears in the fittype4 folder in express. I manually uploaded to Strava and it all appears as a bike with a run workout on the end with 0 min 0metres etc. It will not manually upload to Garmin though.
Any thoughts on why this happened and how to upload. Also why is the whole workout appearing as a bike when I changed the watch to run for 6km at the end?
