Strava- How do I add distance?

If you have a foot pod (and it's calibrated), Garmin will figure out the distance/pace on the dreadmill and it will be reflected in Strava correctly (here's mine from this afternoon - http://app.strava.com/activities/35473515).Not sure about the bike trainer - that one might have to be entered manually. 

I was trying to do that as well. I don't think you can. You might want to email their customer support. Sometimes my watch dies and I cannot add the rest of my run or sometimes I try to edit a run and add distance and I can't. It's also annoying when you run a certified race distance and your watch only shows 12.7 miles for a 13.1 half marathon so strava doesn't count that as a half marathon distance...

You used to be able to. I do not see the option any more.

There is no trainer option if you upload manually...

Here's what I do - I admit, it's completely kludgy, but it works.

1. Upload the Garmin file from your trainer ride/treadmill run. It will get you the time and the heart rate, but there is no way to add distance

2. Manually add another workout with the same start time, add the distance but no time.

This way, your totals (if you care about it for club standings, like I do) will have the total time spent and the total distance covered. The # of workouts will be too high, but I don't care as much about that as I do the time or the duration.

BTW, I use a footpod when I run on the treadmill. Not that expensive, and totally captures distance. Also useful for running outside, as it keeps track of your cadence while running (doesn't hurt to have more data).

The spin bikes at my gym have ANT+ sensors, but it's hit or miss. Typically, I only get them to sync to my Garmin when I'm the first one in the room.
