Bike-commute day 18—gym and home

Chuck emailed me soon after I posted this morning's commute, "Is the new gadgetgizmo broken already?"

I can't answer yes or no. The gizmo works great ...some of the time. When it failed—again—during my afternoon ride, it did so again while there was fairly heavy cloud cover. I also noticed that it dropped into autopause once while I was standing on the pedals, leaning forward. I'll try to reposition the mount, move it more forward, but I can't do anything about the cloud cover. Except ride only on clear, sunny days. See the bike leaning against the wall? Maybe that's my steed on the majority of days in Dayton, waiting for the sun.

The essential question remains: should the 705 be so sensitive, so reliant on a GPS signal at a given moment that it must autopause so readily and frequently?

Bike-commute day 18—to work

Impatience has been my work for the past couple weeks. Only three days where it wasn't raining and I could ride, and I wasted one perfectly good day because I had errands to run in preparation for an Easter-weekend trip.

Today's ride showed some limitations of the Edge 705. At about 14 minutes into the ride, the 'puter began to auto-pause, even though I was riding without a stop. I tried to restart it by pressing the start/stop button, to no avail. Even turned the 'puter off once. Still no help. I suspect that the GPS signals weren't making it through the heavy cloud cover. But that's just a suspicion. I tried to reset the 'puter off the auto-pause, but I couldn't find the control in the software's menu structure.

The path was mostly dry from home through Eastwood Park, but then the way was consistently wet for the remainder of the ride. My slower speed reflects the caution I needed for the wet and for often stopping to attempt another fix for the auto-pause.
