Thanks for the tips guys. I tried to try them today, rode about a mile, and the battery died! Grrrr. But my bad. I'm old school and don't plug something into a charger until it dies. So I have no Garmin stats for today. Glad I still ride with the backup Cateye!

Chinarider, I did exactly that, hit stop, then hit start when done at the Y, and still got the total time (55 minutes) & statistics instead of what I expected, a ride (25 minutes) with a pause.

Tornado, I did NOT hit the lap button, and also didn't think about hitting it while still moving. I realized I came to a full stop, under the portico, so the Garmin likely lost contact with the motherships before I hit any buttons.
Yes, I do have the auto pause running. I will try the lap thing, I haven't worked with laps at all yet. Honestly, I'd love to have the whole ride as one lap, but one lap without the half hour or so I'm in the gym, not moving wheels, so not moving the odo or cadence.

Thanks all for helping a newb.
