Here's what I did today: 24.1 miles on the bike (an out-and-back starting and ending with a slow section through town; stop at the turnaround for a snack). I did a 5-mile warmup and then a series of "stomp" pickups for 1 minute every 5 minutes, visible as the regular heart rate spikes in the graph:
The heart rate meter seemed to work much better this time (perhaps the conductivity was better because I was sweatier and not bouncing up and down as I do when I run), but I'm not impressed with the plotting software. I can't seem to find a way to adjust the scaling of the speed (right vertical axis). That thin squiggle between 15 and 20 mph isn't very helpful!
The average speed from the Garmin only said about 15 mph, while the bike computer average speed said well over 16 mph. That's a big (9%+) discrepancy! Total distance measured seem to be fairly close, though.
While it's nice to also have a little map plot of the workout, I can also do that with gmaps quite easily - plus switch to satellite view also, so that's no big advantage in the Forerunner. Yeah, the cadence function would be interesting, but I didn't have that today and that's still more $$ for the sensor unit.
Yeah, the product still has some drawbacks. It does lots of things automatically quite well, but I need the ability to customize it a little more if the automatic functions don't work how I want.
Weather was pretty nice for the end of November! Not much wind, sunny, about 50*F. I'm enjoying it while it's here, because it's sure not to last!
